I like the Spitfire, it’s my favourite vintage aircraft, but it’s a sad thing that very few seem to highlight the role that Joseph Smith, R.J. Mitchell’s assistant, who took over responsibility for the design after Mitchell’s death, played in the development of the Spitfire. The aircraft designed by Mitchell was brilliant but it was Smith who kept updating the design to meet newer threats and should have, in my opinion, been given more credit than he was.

Interim solutions proved to match and even outperform Messerschmitts and Focke-Wulf fighters. I think Rolls Royce should be mentioned too for the incredible increase of power of the Merlin and the development of the Griffin. Praise for the guys that created the propellor as well? The Spitfire prototype started with a fixed pitch two bladed unit. Went to variable three bladed unit. Then four bladed, five bladed and even a contra rotating 6 bladed unit. Amazing they got it done in such a short time and tooled up to make thousands of units.

Cameron McAllister I'm sorry to say you are quite incorrect. The Hurricane was influential in the defeat of Rommel in North Affrica. The MkIId fitted with the 2X40mm vickers AT gun helped slow the Africa Corps. The Spitfire MkVc (tropical) was more often grounded and was hampered by the huge tropical intake. The Hurricane was replaced by the Typhoon in 1943 which had a much bigger impact over Normandy than Spitfires during operation overlord. The MkXII spitfires only able to do minimal damage to ground forces compared to the Typhoons. over Europe the spitfire became an almost obsolete aircraft as Typhoons, Tempests and Mosquitos knocked out the supply lines for the luftwaffer. The MkIXHFe being used to knock out recon aircraft (until the Mk.XIV) and the Mk.IXLFe engaging the fighters though by late 1944 the tempest was causing havoc to the FW190 squadrons and harrying Me262.

+edmundscycles1 - Both Typhoon and Hurricane (to a lesser degree) were cases of a "failed" fighter turned ground-pounder. Spitfires could do those jobs just as badly, if they really needed to. Tempests were better, but it took lots of time to figure out this new engine/airframe combination. To the point that it became unnecessary before it entered service, and a known stop-gap measure for most of the time it was actually used. At least it actually worked, unlike Saber in Typhoons.

Under primitive airfield conditions, the Hurricane would enjoy a greater serviceability rate as well. Repairs to the Hurricane could often be done without the specialized facilities and training needed to keep a more modern, stress-skin design in the air. War on the frontiers also tends to have fewer cameramen and journalists, as well...

The Rolls Royce built Merlin engine is universally acknowledged as one of the finest piston engines that has ever been manufactured. Remarkably, over 50 years have elapsed since the last Merlin engine rolled off the production line, yet it is still in widespread daily use in warbird aircraft, including the P-51 Mustang. Just as North American Aviation would never have envisioned their Mustangs would still be flying, Rolls Royce probably never considered that their beautiful Merlin power plant would still be in "front line service" in the 21st Century.

I joined the RAF in 1979, after all the training I did on modern aircraft the first thing I ended up working on was a Spitfire from our museum flight, it kindled a fascination for the aircraft that I still have to this day.

If you are interested, I highly recommend Sir Stanley Hooker's book 'Not Much of an Engineer'. He goes into an additional dimension of why the early Spitfires were carbureted: 'Let me now add that the Germans paid a large penalty for their fuel injection. When the fuel is fed before the supercharger, as on the Merlin, it evaporates and cools the air by 25° C. This cooling enhances the performance of the supercharger, and increases the power of the engine, with a corresponding increase in aircraft speed, particularly at high altitude.' (p. 62) The Spitfires could run their superchargers at higher boost, and this put them in a place to take best advantage of the 100 octane gas coming from America. Hooker claims they were able to get 2000 HP out of a Merlin as a result of this. Combined with the weight and cost savings, carburation seems like a perfectly valid design choice under the circumstances.

@EvidensInsania

6 жыл бұрын

The 2000 HP Merlin engines came later but yes, carburetors did allow the British and Americans to always have more horsepower from their engines than German fuel injection. And by 1942 they had pressurised carburetors in Spitfires and Mustangs that completely eliminated the negative G engine cut out. The main reason carburetors have mostly died out in engines these days is because of the requirements to use catalytic converters to reduce the amount of pollution released and catalytic converts require a very precise mix of fuel and air that you can only really achieve with fuel injection.

@andrewwmacfadyen6958

It is often ignored that the BF-109 had a bigger engine not as big as the Griffon but considerably more swept volume than the Merlin. Having worked on car with the early German mechanical gasoline injection Rolls-Royce were very wise to stick with the carburetor produced by SU (nb. not an SU Carburetor) then go to pressure carburetor / single point injection The 30/70 glycol water coolant of the Spitfire of the Merlin II also allowed a specific power increase.

@bobsakamanos4469

18 күн бұрын

It should also be noted that Stanley Hooker designed the 2 stage supercharger with an intercooler, aftercooler and backfire screens which allowed the optimum performance of 2 stages. The Allison, by comparison was never designed properly to take their auxilliary supercharger, relying only on water injection to prevent detonation - it wasn't effective. NAA knew this and railed against such a project by Allison because it wouldn't be easily fit into the Mustang, and they immediately started looking for an alternative engine in 1941 for the Mustang. The Merlin was eventually tested for WEP bursts of 2640 HP, but jet engines were on the way by 1944.

one used to be kept at the airbase at colerne up until last year, it was a pleasure to see it fly, the way it would defy gravity in loops and rolls and the sound of its engine was superb. I saw a p51 owned by the same guy come in to land there too. Privileged to have seen them in real life.

Your videos are always worth watching, both informative and entertaining, but I think you missed one important difference between the Spitfire and the ME 109 : the armour plating on the ME 109 was thicker than the ultra-light aluminium skin of the Spitfire, which made it far less vulnerable to machine gun bullets, whereas one single hit from the 109's cannon would destroy the Spitfire. Spitfire pilots (during the Battle of Britain, when they only had machine guns) would have to get closer to their targets than their enemy had to, in order to guarantee hitting the target and causing notable damage.

Seize is really the wrong word, stall or cut-out would be more appropriate. I understand hesitancy to say stall as we like to save that word for the wings but in this case it would apply

engine floods , float in carb opens up under negative G, float bowl in the carbs fill with fuel , engine floods with fuel and cuts out due to over rich mixture ...Is that right ?

@EeekiE

6 жыл бұрын

Jonathan Vogel the float floats on top of the fuel at the now bottom of the carburettor chamber due to it being under negative G. This opens up the fuel chamber to the fuel pump’s pressure, and when it fills, the full pressure of the pumps is being injected into the engine, resulting in a massively rich mixture and flooding. The fuel pump’s job is only to keep the fuel chamber of the carburettor topped off. The quick fix solution, suggested by a female engineer, was to simple restrict the rate at which the fuel pumps could top off the carburettors fuel chamber to the same flow rate as the engines would require at max power. That means that when the same thing happened, the pumps would only be forcing fuel through the carburettor’s needle at the rate they’d be being pulled in naturally anyway, providing the engine was at full power. You’re only really going to be doing those manoeuvres at full power anyway, so it was good enough. You see a lot of half answers about this from people that clearly don’t know what the problem or solution was and how they worked, but they know it’s ‘something’ to do with flooding/stalling, and the fix was ‘something’ to do with a small hole to restrict the fuel somehow. All you need to know is that how carburettors introduce fuel into the engine, is a separate system entirely to how fuel pumps feed a carburettor’s own separate little ‘tank’ that it works with. Carburettors are constantly sipping from a cup, and the main pumps periodically top up that cup very quickly. When the carburettor is ‘erroneously’ demanding to be filled up, but it’s already full, because it’s way of measuring how full it is is inverted, then it effectively links the two systems together and now the high pressure, high volume ‘topping up’ pumps are working at full duty, straight into the engine. Using the teapot, teacup analogy, the fix was to put a restrictor plate on the end of the teapot, so that it could only pour as fast as a teacup would be drunk from when someone is really gagging for a brew. So it could still flood when inverted/neg-G at part-throttle, but never during full beans.

Very interesting and well done! I've read multiple books on the Spitfire and usually find several mistakes in most videos on the Spitfire. Good to see an accurate one!

Stanley Hookers book "Not much of an engineer" refered to "Mr. Royces" comment when Hooker was set a task of , could he improve "Mr, Royces" design of impellers on the superchargers "honed to a fine pitch/tune" by the great man. Hooker at this time still not fully engaged in the war effort that he so dearly wanted to take part in, thought he'd look at the calculations and graph curves, air speeds and compression within the supercharger unit and rework the figures, which he found could be possible and far more efficient. At this point it must be said that Royce had his canny engineering skills and "feel" for what would and would not be successful in his "aims" and when he achieved this in practice not the "theory" and was achieved, moved onto something else. Hooker on the other hand was of the "new school" where things where worked on paper i.e. theory, then down to the "tool shop" and discussed with the engineer on the practical side , i.e. materials and how it was to be achieved following Hookers design and drawings. At this point the mechanical engineer in the said tool shop pointed out to Hooker that "the old man " Royce wouldn't be happy that Hooker had been "messing" with "his" s/charger design. When Hooker approached Royce with his projected calcs. and drawings on how he could not just improve the performance of the s/charger but by a considerable amount, at which point Royce pointed out that this was just on paper and that real engineers where very aware that theory and practice hardly if ever went hand in hand with each other. Hooker now more than ever wanted to prove that his "paper figures" would work in practice and with very few alterations he managed to improve the performance by such a vast performance that so nearly tallied with his theory figures, on one of those very few occasions that it actually happened. When sharing with Royce that he (hooker) was very pleased that he managed to help the "war effort" in this way, Royce said "not much of an engineer" to take another chaps design and only improve on it, rather than start from scratch as indeed he Royce had done. And of course indeed the great man Royce had that ability to think and do what was needed to overcome or rethink a given situation or problem, then actually have that engineers skill to know what material to use and how to create what he had in his mind, and bring to fruition . Truly a great man and engineer.

Just being pedantic.

Negative G's or flying inverted caused the float to close the fuel inlet stopping fuel flow into the carb.

Hi biz. When the plane was pushed in negative G, it didn't seize the engine but rather starved it of fuel as the carb had a bowl with fuel in it that was forced away from the pick up due to the G maneuver. Flying inverted was only dodgy if it was sustained. As long as the plane was pulling positive G, even inverted, it was fine. reat video series btw.

Had Westland stuck with the original propellers of the prototypes, they may have had more support from the Air Ministry/RAF as a bomber destroyer; however, RR simply didn't have the manpower or capacity to refine and produce both the Merlin and Perigrine engines.

I note several misconceptions developing here. First, the performance of the aircraft is relatively unimportant, its pilot skill as pointed out by Galland, but more importantly being in the right place, and in this respect the RAF had the advantage. The early warning system set up by Dowding and so expertly used by Parks was the key to the RAF success. The RAF could fight on its terms, and not those dictated by Goering. Second , as the efficiency of a engine is defined by the Carnot principle. Carburated engines are more efficient because the fuel entering the engine is so much colder, hence a 27lt merlin produced the same or more power as the 38lt Daimler. UK also had access to 100 octan fuel which also allows significant improvements to be made throughout the war, but its not unlit the war is nearly over that Germany starts to introduce the improved fuels. Third, cannons do little damage to Hurricanes unless it hits the engine, and in Hurricane to 109 encounters the Hurricane is a competitive match. Forth, as Sailor Milan pointed out , a damaged aircraft returning with badly injured crew has an even bigger negative effect on moral, than not returning at all, so kills are not the whole story.

Hurricanes had less performance and therefore were more vulnerable than the Spitfire. Each had the same vital points (engine, oil system, coolant system, pilot) except that the Hurricane's header tank was not protected (causing many Hurri pilots to be burned) and its wing tanks made for a larger target and the doped fabric/wood rear fuselage was flamable. It wasn't normally competitive and had the worst kill ratio of the Battle.

The tool is only as good as the individual using it. Being honest the merlin engine sounds wonderful and the design of the aircraft was excellent but so were so many aeroplanes of that era. It will always be held high esteem due to its use during the Battle of Britain and the turning point of the 2nd WW. Thanks for your video.

"A" wing was all guns only. "B" wing was a mix. "C" wing was 4 cannons. "E" wing could be done in any configuration. Prior to the "B" wing there was a short period with 2 cannons only. Once the wing was beefed up, it could handle both cannons and guns. The wings with a bulge underneath, or a pair of bulges were for cannons. The "A" wing had no bulges. Note, the photo recon spits had a much larger wing in length and width that allowed it a much longer range, speed, and altitude. The PR spit used the empty gun spaces for extra fuel, thus giving it a Berlin range. Unarmed.

There are two major factors that helped the Spirfire (and Hurricane) over the 109 during the battle of Britain: 1) Benign stall characteristics in a tight turn, a Spitfire had benign stall characteristics in a turn. When a pilot got close to a stall situation the stick would start to judder warning of an impending stall. The 109 on the other hand would give no warning and would depart violently. Ironically the 109 with its combat slats could out turn a Spitfire but it required a highly experienced pilot to take advantage of it. For the Spitfire (and Hurricane) a new pilot could perform tight turns without fear of stalling the aircraft. 2) Fuel, arguably the biggest advantage the RAF had, operating out of home bases RAF fighters had more fuel available for combat whilst a 109 was limited to a few minutes.

Even with combat slats the 109 could not out turn a Spitfire, especially at faster speeds where it was literally impossible to turn a Bf 109 but the Spitfire elevators were still very light. The Mk II Spitfire pilot manual actually specifically says it was well within the pilots ability to pull 10G's and to therefore treat the controls with respect. And the bf 109 slats were an absolute disaster anyway. They could often deploy asymmetrically and get stuck ruining the stability of the plane. If the Bf 109 was behind a plane then the slats could also be deployed simply from the slipstream of the leading plane and when the slats were open they caused aileron snatching making aiming impossible. There is a reason why Kurt Tank didn't include those awful slats in his much superior Fw 190.

The RAF switching over to 100 octane fuel between the Battle of France and the start of the Battle of Britain gave the Luftwaffe quite a shock. The Luftwaffe weren't too impressed by the performance of the Hurricanes and Spitfires they captured in the Battle of France and were expecting the same thing in the Battle of Britain but instead the 100 octane fuel allowed the Merlin engines to run at 12 lbs boost instead of 6 and they were all fitted with much more efficient propellers. The fact that most of the RAF in the Battle of Britain were made up of brand new recruits who had only received 10-20 hours of training before being sent into battle consistently outperformed their Luftwaffe opponents, most of whom had gained a lot of experience fighting in Spain, Poland and France, is a real testament to the quality of the Hurricane and Spitfire.

But the Spitfire won on ergonomics (more room for pilots elbows and better laid out cockpit), visibility (better canopy) and survivability (Spitfire had an armoured cockpit). IE: As a pilot it was easier to get the best out of the Spitfire and if you were shot down , the chances were that you would liv to have another go.

Well presented and very informative. Thank you. A footnote about Hurricanes in the Battle Of France: I have "Fighter Pilot" by Paul Richey, which tells the story of No 1 Squadron's campaign while based in France during the battle. The bottom line was that, even when fitted with a fixed-pitch, two-blade wooden propellor, the Hurricane, when flown by seasoned pilots, could hold its own against the Bf-109 and was superior to the Me-110

Brilliant, thank you. Very helpful. M.

What's amazing about the video, which is very accurate and well explained, is the debate which follows. Some really good stuff about engines, the pro's and con's of carburetors versus injection, about weaponry, the muzzle velocity of .303 vs 20mm cannon. What is absolutely astounding is how some people talk about aircraft characteristics based on their experience in flight simulators, which have all the difficulties in the world trying to accurately replicate flight models and engine performance of the real aircraft and where game editors have often taken liberties with the true historical characteristics in order to improve gameplay. I had a good laugh with the "revisionist" post about the Hurricane being superior to the Spitfire, using arguments about the Spitfire that are simply not true. This is a pity as the Hurricane was a good aircraft with many advantages, a stable gun platform, an airframe that could take more punishment than the Spitfire, which was present in far greater numbers than the Spitfire during the Battle of Britain and being the preferred mount of many fighter pilots at that time. I am sure there are many more worthy arguments about the development of the Hurricane, but it became progressively outclassed as a front line fighter, a role for which Hawkers successfully developed new types of aircraft.

Interestingly some of the last operational Bf109 airframe operational were built in Spain and used RR Merlin engines and were what we saw in movie "Battle of Britain".

It's my understanding the RR Merlin could accumulate only 100 hours of flight time during those years before it was required to be replaced with a new engine. Removed engines could only be overhauled once, and were limited to 50 hours of flight time before replacement.

The misconception about cannons during the battle of Britain and also the use of Spits in France might be partly from the TV series Piece of Cake. It's overall quite excellent, and well worth watching for anyone who hasn't, but some historical inaccuracies were unavoidable. The book which was the basis of the TV series used Hurricanes, but at the time it was made (1989) there were not enough airworthy Hurricanes available to allow for filming of the flying scenes, so Spitfires were substituted. Furthermore, the aircraft that were available had mostly been built later in the war, and so had the cannon armament. In some scenes aircraft even have the enlarged tail that was not introduced until very late in the war. These are not cases of filmmakers overlooking historical details, simply a matter of the difficulty of finding enough airworthy aircraft to make filming possible at all.

Very very good stuff. However Re the Hurricane: it was a very usefull fighter and did shoot down a fair share of 109's and most of the bombers in the battle of Britain. It was certainly capable and in fact considered more powerful than the 109 at up to medium altitudes and only lost out at higher altitudes due to the supercharger tuning of both fighters (cant have it both ways with a single stage) .. Hurricane development was essentially stopped because the Spitfire was deemed to have more potential at high altitude where the 109 was lurking and where a fighter needed to be to respond quickly to raids . It also competed with the Spitfire and other bomber aircraft for Merlin engines. The new Hawker Typhoon was well on the way and would need manufacturing space . That new fighter would not use a Merlin engine. Interestingly this is the same rational for Kurt Tanks Fw 190 a previous reject getting a second chance. The Luftwaffe wanted a fighter that would not use the DB 605 engine. It used the BMW radial and it turned out a great fighter as well. Then of course came the great Hawker Tempest as the improved Typhoon was called. But at the time of the Battle of France the Hurricane was a good unit.

The Hurricane was produce for far too long, production ending in 1944, but it was already obsolete as a front line day fighter by the fall of 1940 or earlier.

I have always argued that the Spitfire is the best fighter if the war simply because it remained a very serious opponent from the first day of the war to the last. Many of the other "greats" weren't around from the start, and those that were weren't nearly as competitive by the end of the war. No matter what fighter an opponent was flying, including the Me 262, an engagement with a Spitfire was a deadly serious matter.

Excellent production, Bismarck. Another problem about the early cannon firing Spitfires had to do with the way the cannons were placed. As not to interfere with Mitchell's wing design, the cannons were placed on their side, and the ammunition feed was placed laterally, that feed following a non-linear direction. The guns were not meant to fire this way, but they were tucked in the wing without interfering with the wing design and construction. Designer Joseph Smith deviated from Reginald Mitchell's design by introducing the now famous tear drop bubbles on the wings, allowing for a proper ammunition feed. Then there is the rather bizarre story of Douglas Bader and his criticism of adding cannons. He believed that the .303 machine guns were better as it encouraged the pilot to close in on the enemy. He spent the rest of his combat duty flying a Spitfire Va, a Mk. V with the traditional eight .303 guns. Well after the war, he admitted to being wrong on that point.

Really interesting. Never knew that cannon-mounting Spitfires flew in any shape or form before 1941.

Thanks for an interesting video. One minor observation: I'm pretty sure your graphic of the .303 MG is upside down. I can't speak about the aircraft version of this gun specifically, but I know from personal experience that the standard land-based version couldn't operate for very long in this orientation as it relies upon gravity to remove the spent cartridges downwards once they have been pushed clear of the "T" slot on the face of the bolt. If fired upside down, spent cartridges would quickly accumulate at the (now upward-facing) bottom of the bolt and eventually fowl its operation. Again, I'm assuming what would apply in this case to a land-based .30 cal would also apply to an aero .303 MG.

Big problem with the Mkiib cannon spit was wing warping during high turns. The wing would bend, jamming the feed system of the 20mm cannon. The Mkvb had a new wing ( retrofitted to Mkiib as the wing became available) this cured most of the issues. After October 1941 the 'E' wing (universal) became available. This wing could be clipped, have multiple gun setups such as ; 8 X. 303, 2 X 20mm + 4 X. 303 or 4 X 20mm. The later Mkv could also carry a single 250lb bomb in the center line. The Mk ix became a answer to the Fw 190. with the merlin xx engine and the 'E' wing as standard. Of not is the new wing again fitted to the Mkix and Mkviii after several accidents while dive bombing.

It is important to understand that having the fuel introduced by a carburettor before the supercharger cooled the air by about 25C (due to the evaporation of the fuel) and thus increased the density of the charge entering the cylinders and increasing the power output of the engine compared to a direct injection system where the evaporation occurs too late to increase the charge density and this is the reason Rolls Royce continued with various forms of carburettor (Bendix-Stromberg pressure carb. and then SU injection carb.) for all the Merlin engines.

Carb vs injection. Carb was bad at *sustained* negative G. Spitfire pilots learned to roll inverted to follow a 109 into a dive. RR preferred the carburetted engine as it was able to deliver more power, due to charge cooling at the carb. Alleviated by a fuel restrictor (developed by pioneering female engineer Tilly Shilling, and so called Miss Shilling's Orifice) and fixed by the introduction of, first, pressure carburetion, and then injection into the supercharger inlet, both dispensing with the float chamber. All-20mm cannon armament was the aim for the RAF, but was not reliably usable in the wings of single engined fighters until a new feed mechanism was developed (belt vs drum) RAF cannon-armed fighters were not a factor in the Battle of Britain. The cannon worked well in the nose of the Whirlwind, but the decision to stop Peregrine development meant that this rather impressive single seat twin engined fighter was never developed or employed in large numbers. The US were sent Hhispano cannon in the hope that they could produce them in large numbers. Unfortunately they made changes to the weapon that meant it was never reliable, suffering stoppages unrelated to those found in RAF service, and leading the USAAF to stick with the .5 Browning long after everyone else was fitting cannon as standard. Kudos for referencing Tony Williams, whose works on guns and ammunition (with Emmanuel Gustin) are concise, accurate, well written and a good read.

I mentioned pressure carburetion, which was performed using the Bendix-Stromberg carburettor. First applied to the Merlin 66 which powered the Spitfire Mk.IX. The pressure carburettor is a device that replaces the float chamber, from which fuel is drawn by depression in the throttle venturi, with a pneumatic air metering device that controls the fuel quantity injected. This does away with the float, but is in other respects still looks like a carburettor. It is, in effect, a single-point injector. The Bendix-Stromberg was later replaced by an SU injection carburettor, a further-developed form of mechanical fuel injection that again injected at a single point, into the supercharger inlet. So the Merlin *did* adopt fuel injection, but in single-point rather than multi-point form. This was quite deliberate on the part of Rolls-Royce, who made use of the charge cooling to increase the density of intake charge and develop more power.

This gives excellent clarity, being English I grew up being in awe of this airplane. Luckily I have seen it fly and heard the sweet sound of the marlin engine, unforgettable. However we do wax lyrically about it and gloss over its short comings. During the Battle of Britain the German fighters were at a severe disadvantage, due to fuel and orders to stay with the bombers! I think an engine cutting out due to normally aspirated carburetors, compared to advance fuel injectors is a major disadvantage. Glad the lady that helped solve the issue is recognized here😁 Having see both the Spitfire, Hurricane and 109 next to each other, noted the 109 was a much smaller plane. Wonder if any tall pilots ever flew it, if they did sure it was uncomfortable? Finally the Hurricane was always the bridesmaid to the Spitfire, but was a star in it’s own right and much easier to build.

One thing that wasn't mentioned was that the early Hispano installations used a 60 round drum (pictured in the video). Aside from the jamming, it also required large blisters to fit in the thin Spitfire wing. The later installations used feed trays and 120 round belts. According to the Wikipedia page the Hispano had a firing rate of 700 rpm, so 60 rounds would indeed last 5 seconds. Lots of comments below on the C and E wings - the first 2 cannon + 4 MG installations were actually in the B wing (cannon in the inner machine gun bays with the 60 round drum). The C wing was the definitive 2 cannon + 4 MG wing, it could also be fit with four cannon (almost never done), OR 8 MG (almost never done), OR (theoretically) four cannon AND 4 MG (NEVER done, too heavy) OR two cannon and two .50 MG (only late in the war). Hence "Universal". The E wing was for two cannon + two .50 MG (the cannon mounted outboard of the MG), also late in the war. The Spitfire FR XIV (with the teardrop canopy and side camera ports, as pictured in Quill's book) at the Royal Thai Air Force museum in Bangkok has the E wing. I never thought I'd ever get to see one of these in real life, here you can not only lay your eyes on it, you can fondle it! (Definitely worth the hour long unairconditioned Bangkok city bus ride... they also have a Fairey Firefly, by the way - HUGE - and a Harrier - yes, the Thais operate a carrier, albeit only with helicopters, these days..) The D wing, apparently, was for PR Spitfires (no guns). I see some interesting comments below on Spitfire operations out of Darwin, I've been wanting to find more information about this but haven't found all that much (online). I did hear they initially had a terrible time of it, they brought a veteran squadron from Britain to take on the Zeros and ended up losing something like 18 pilots in a few months. Some of the stuff I found online mentioned the huge distances involved - there was a map of many, many emergency landing strips since there was a real danger of running out of fuel on operations. Caldwell is mentioned prominently in the P-40 article on Wikipedia - did he ever write a book? Didn't know he flew in Australia later on.

iskandartaib 1. The Mk IX had 2x canon and 2 x 50 with the Ewing and it was not a late version 2. The Aussie Government held Churchill to his promise of Spitfires being sent Churchill sent clapped out MkVs Churchill [ the slug] was angry at us because we brought the Australians back from Africa and used very trick in the book to oppose it. Eventually we got VIIIs but the Spitfire was never really suited to the SW Pacific . Too far between Areas of Operation

The RAF reconnaissance Spitfires were really clever. The photos they took were actually in 3D which allows the intelligence staff analysing them so much more information and detail that they wouldn't have with normal photos. They could tell exactly how tall structures and defences were for planning attacks including the dam busters raid. They also allowed them to find the V2 rockets being developed, with normal photos a V2 would just appear as a tiny round circle on the ground but with their 3D photos British intelligence was able to see exactly what they were and even their exact height so air raids could be launched at the V-2 research centre and delay their development.

Evidensinsania: Not only Spitfires; the predominant PR aircraft in the RAF was the Mosquito. The British had pioneered the use of stereo pair photography in WW1, and made extensive use of the technique in WW2. It was therefore well-known to all sides in WW2, yet the Luftaufklärung units did not make any great use of it. Perhaps worse is the fact that the Wehrmacht had no central specialist reconnaissance organisation like the PIU at Medmenham, and that most reconnaissance was tactical in nature. The measurement of ground features using Swiss Wild Heerbrugg stereoautograph machines allowed for the construction of accurate models of ground features to prepare for critical missions (the Dam Busters mission is the one everyone remembers - and those models were made at Medmenham) as well as accurate sizing of items like the V1 and V2 prototypes.

Very nice! Thanks.

By the last 12 months of WW2 in Europe, Spitfire operations were curtailed in great part due to the more capable, versatile and numerous P-38 and P-51 aircraft. The Spitfire had fulfilled its role and the more plentiful and powerful American planes finished off the Germany from the West as the Soviets did from the East.

As a very young kid I experienced the appearance of the Me262. Jg7 under Nowotny It messed up the Allies real badly. The lack of fuel saved the day for us. Nowotny himself had over 100 kills, a lot of them P51 and P47. . Once the Me262 appeared all other fighter planes became obsolete over night. We got lucky with the Me262 and the U-boot Type 21. Not so lucky with the Panther, Tiger, Mg42 and the Sturmgewehr. I forgot the Panzerfaust. A Reichsmark 200 weapon knocking off US$ 75,000 tanks. The U.S. lost 7,000 tanks in WWII mostly in France and mostly Shermans. The Germans called them "bunsenburners" . I do not know British losses, but those were very substantial too.

2:33 Spitfire crashed into the He-111...

After the liberation of France, there were lots of hangers found with unused aircraft, including ones sent by the British. It’s almost as if the French politicians wanted someone to blame for the defeat more than they actually wanted to fight. Sending more fighters, as Churchill wanted to do, would have made no difference to France, and a significant difference in the Battle of Britain.

France had some excellent fighter designs available, only the heads of the military and politicians didn't realize how badly they were needed. They were well able to match the 109 and might have changed history, had they been available in numbers.

Well the sad fact is that they did have plenty of good planes... only the pilots (and their officers) were hot-legging it to Normandy or just giving up. That's why Churchill & co were reluctant to send many of our planes over (incl Spits) and just placated the French generals with some Hurricanes and Lysanders etc.

Possibly, but from what i understand there was a shortage of pilots. This was bad planning of course but it took several years for the allies to get there act together. E.g.Crete, Hong Kong, Singapore, Russia, Pearl Harbour. France was the first major power to face the German forces.

great video!

I found this to be a good cogent well informed presentation. I am new to this channel and hope to find a discussion of the Browning .50 that was deployed in later platforms. I do not know if Spitfire ever used these. The extreme example would be the P-47 with eight of these guns.

David Rapalyea: some MkIX and MkXIV's used 2x.50 brownings + 2x20mm cannon

The 109E having a squared off wing design is a more significant shortcoming than the early spitfires using a non-pressurized fuel solution. Furthermore, the 109E used circular 20mm magazines in the wings forcing the designers to include a bulge in the wings, causing aerodynamic drag. The spitfire used guns in the wings as well, however the magazines could fit into the wings without the inclusion of a bulge. The 109F model, would rectify the major issues with the E model. Model F1 through F3 would utilize an oval wing design, while the model F4 and forward would use the Daimler 601E engine, as opposed to the 601A and 601N used in the 109E and the early 109F models. From the model 109G and forward, the Luftwaffe would use the 605 engine, with several variations depending on intended altitude. Armament would also change depending on intended target, using up to 30mm auto cannons for bomber hunting. However, when the Royal Air Force started using the Rolls Royce Griffon engine. There was no longer a contest.

Talking about top speeds of the Bf 109 G and K is laughable. Sure they managed to push them to decent enough speeds under ideal test flight conditions (still less than Griffon Spits and Mustangs) but it was impossible to actually manoeuvre the bf 109 at those speeds, all the pilots who flew them consider the Bf 109 to have the worst high speed handling of all the main fighters. Adolf Galland actually wanted their production to be completely scrapped in 1943 because of how hopelessly outdated the design had become.

From everything I've heard, the MkXII was an absolute beast at low altitude, but that's because its single-stage Griffon was rated for down low. The XIV, XXI, etc were optimised for high altitude, but that was rapidly becoming no longer the place for piston-engined aircraft.

Hi, Andre. I recently found an old letter I wrote about this topic some years ago so I hope you don't mind the length. I edited it a bit to address some of your points but it's largely intact. It's more of a reminiscence than a lecture so I'll dive right in. The only solid advantage the Spit had over the 109E during the BoB was range. Head to head it, as always, just mattered who took advantage of his relative strengths. The DB 601 was a bit too much engine for an airframe that was essentially the same as the prototypes that flew on 650hp but the wing tips were not a big factor. They were used to make maximum use of the wing slats to keep the low speed handling a bit less terrifying. They also provided a generally good rate of roll but the ailerons would get stiff at high speeds, just like the Spit, because the bigger engines pushed the speed above the original design parameters. The rounded tips on the 109F and later were to reduce the high speed stiffness and to reduce the flight loads on the new wing spar. They really didn't change the handling all that much. The 109 could be treacherous if handled roughly, had some flaws, and demanded a skilled pilot but it wasn't dangerous or inherently difficult to fly. It's biggest flaw was the landing gear which has been described as "even worse than a Spit!" After the landing gear; the wing slats were a mixed blessing. An inexperienced pilot who got into a condition where one or both slats would pop in and out could cause a fatal spin. But, once the plane was in a low speed configuration with both slats firmly out it wasn't any more treacherous than most any other similar fighter. Better training would have helped a lot but I'll get back to that. Having flown RC scale models of several Spits and 109s I can attest that a Spit's inherent wing design is more treacherous than the 109 but the difference in scale means that a model 109 will almost always have a lighter wing loading than a Spit of the same scale which, of course, is the opposite of the "real" aircraft. But, just like the real aircraft, the 109 flies like it's on rails while the Spit will "swap ends" as fast as you can think it and both will bite if you try to drag them through a low speed turn without power. After the Winter of 43-44 it didn't matter much what the Allies were flying. All Allied fighters were scoring better than 1-1 by then. That includes some rather dodgy Soviet fighters and the P-39's they flew after the U.S. gave up on them. By this stage of the war the average Allied pilot was well trained in the use of his fighter and taught tactics that took advantage of it's strengths. If he spotted an enemy in a "superior" aircraft he didn't look to hide; he looked to use his training and equipment to shoot it down. The Germans and other Axis pilots simply couldn't measure up despite flying some fighters that, when they had gas and maybe some nitrous, appeared to be able to out perform their counterparts. And that doesn't include the Me262. The axis powers were defeated in the air by logistics; especially the logistics of training. They depended on a short war and expended their most talented pilots in a battle of attrition instead of preserving them to train the next wave. And that one thing is arguably the single greatest factor in the turn of the air war. The Germans could produce a large number of very capable planes but they squandered the ability to train skilled pilots. The Japanese even managed to produce a surprising number of potentially good planes, to a low standard of quality, but they were so warped that they were sending out skilled pilots as kamikazis because there were no more unskilled pilots left! If you read biographies of the aces from both sides you will see this difference clearly. The Britain and the U.S. used a very fluid system that spread talent within a fighter wing/group that would start with a cadre of experienced leaders that were often on a kind of TDY to serve until the newer element leaders were ready to lead a flight, squadron, etc. They would also rest their pilots, though there's some argument about how restful it was, by assigning them to operational training units. This resulted in the strange phenomenon of frequently reuniting with old comrades in new posts and forging bonds with new comrades. The Axis accounts, on the other hand, are a dirge of loss. Old comrades simply dwindle until they don't return. BTW. The old biographies are great to learn about tactics and personalities but take anything presented as "technical data" with a grain of salt. There are a lot of reasons, most of them honest, why somewhat dubious data ends up in biographies. Cheers!

An almost unknown detail. Originally, the Spitfire's engine was intended to be steam cooled. Steam cooling in theory has several advantages , the principal ones being that boiling the coolant rejects (transfers) much more heat than simply heating it; the second is that you don't need a drag-producing external radiator which, together with its coolant lines, can bring the plane down if a single rifle-caliber bullet strikes part of the setup. Because of this, Reginal Mitchell had the wing designed with a hollow leading edge where the stream would be condensed, which also functioned as the leading edge spar. The steam cooling was one of Rolls-Royce's few failures, so the aircraft was produced with conventional external oil and engine coolant rads. and what would have been the condensers remained empty, with m/gs and cannon barrels going through. However, they were put to use as extra internal fuel tanks for the unarmed photo-reconnaisance versions. Later in the war, using these and also an extra fuel tank behind the pilot, the photorecce. Spit had a range of 1,700 miles, some 200 more than the famously long-legged P-501D Mustang.

I keep trying to add a reply and failing, fourth time lucky. During the early 1930s R J Mitchell designed a fighter around the RR Goshawk engine and it had evaporative (steam) cooling. That machine, the Supermarine 224 had an inverted gull wing and a fixed undercarriage, the cooling surfaces, pretty much radiators, were faired into the fat spats around the undercarriage. It flew but was NOT a success, however Mitchell credited it with providing a number of key lessons which significantly informed his design for a rather better known low wing monoplane fighter. The irony is that the spec he was working on was for a replacement for the Gloster Gauntlet and in the end the Ministry went with the Gladiator - air cooled engines I believe. Who knows what sort of machine the RAF would have fielded in the end if Mitchell hadn't worked on the Type 224. He knew that evaporative cooling worked in principle, but the then working examples were relatively slow biplanes some placing the cooling surface on the top plane. The obvious exception was the S5/S6/S6B series, the S6B anyway, more Mitchell designs, made the corrugated fuselage the cooling surface to maximise the surface area. That's too big a target to use in fighter. I wonder when he ditched steam cooling for the Spit, or was that driven by RR ? He also designed the Walrus, with its air cooled radial - or flying gas ring - nothing if not versatile that man.

Thank you for this video, I like to learn this things :)
