He sounds like a silly old goat past it to me. He's the guy who said the Me262 was faster because it had swept back wings - but it didn't - they were only slightly angled. in this video he makes several mistakes - eg his definition of critical mach number is wrong. he also said a propellor aircraft can't fly faster than mach 1 - also wrong. It was piston engines that were the issue - they can't produce enough power in a given volume and weight. At best Winkle Brown is a pilot equivalent to my wife, who is a very competent car driver. But she wouldn't know a con rod from a tie rod - she doesn't need to. Winkle Brown no doubt knew as much as anybody about piloting aircraft. But in talking engineering matters, he doesn't have it.

But there are some interesting stories about the first few times the P-38 L appeared in combat. Luftwaffe pilots would go into the typical steep dive to evade a P-38 knowing that it normally could not follow, only to find it right behind them popping off with the .50's and 20mm...

This video is ALSO one mans opinion. And it contains several errors in the theory of aerodynamics and also in their explanation and examples. This is a pilot informing pilots, not an aeronautical engineering course. There is no case of the P-47 angering into the ground due to compressibility. It had no issues diving to, or exceeding 500mph. The P-47 training video strongly cautions against split-S type maneuvers and shows that below about 20,000' they can be fatal. Not due to compressibility, but due to how rapidly the aircraft gains speed in a dive and how much energy it retains and cannot be gotten rid of. At 550mph, a 6-G pull up (about the limit of sustained G for a human seated vertically), results in 3,370 foot radius. That is 0.65 MILES of altitude required to not clip treetops, or black out. The P-47 could split-S at 20,000' and 400mph level speed and exceed 550mph before even reaching the vertical portion of its dive. Easily blowing they this amount of altitude in 24.8 seconds at 550mph. This has nothing to do with mach limits. It is entirely physics based. Because it was so powerful, fast, and dense. Pilots generally loved the P-47, and ALL unanimously praised its dive performance. And often cite that advantage for reeling in a german foe or for evading them easily. Many, many kills are credited for forcing the enemy to crash as the 109 would fail to pull up where the P-47 could, after luring them into a dive. Several famous aces have this exact story in P-47s as well at Spitfires and even mustangs.

He did not do a ground attack evaluation, carrier suitability evaluation, or even a dog fighting evaluation, or otherwise make sweeping generalisations despite it sounding that way when taken out of context. The guy was hands-on evidence-driven to his core, in every case he's talking about something he has personally analysed or experienced and his comments are accurate in the context of that situation or problem.

The P-47 was not known to auger in due to compressibility. That was a P-38 problem. The P-47 severely lacked in range and could not provide cover over the target.

If the Brits would have equipped Spitfires with long range tanks in the wings, aft fuselage, and actual droppable tanks, the Spit would have solved all these problems.

Yeah and it's Toni Hackl shooting it down. Look him up.

Brown mentioned the "laminar flow wing" used on the P51, but as it turned out, its biggest advantage, higher critical mach speed was completely accidental. At the time (late 30's, early 40's), small scale wind tunnel tests with carefully prepared wing sections showed dramatic drag reduction with these airfoils from large runs of laminar air flow. What was not realized at first was that the profile and surface finish required to routinely achieve laminar flow was beyond what could be practically achieved in production aircraft. The hoped-for drag reductions and speed increased were not achieved on production aircraft. FWIW, the "Davis Wing" of the B24 also showed remarkably low drag (from laminar flow) in wind tunnel models but not in production aircraft. The profiles of these "laminar flow" wings, however just happened to accelerate the airflow more slowly along its cord than previous designs. Whereas the thickest part of most wings of the time was about 25% from the front, it was 50 -60% back on the laminar flow designs. The result is that the air on top of the wing did not have to speed up as much and would stay subsonic longer. It is easy to see the differences in profiles in a side-by-side comparison. The interesting properties of the Spitfire wing at critical mach were just dumb luck, as the designers had no knowledge of critical mach at the time.

@@jacktattis The Spitfire used the older NACA 22xx series airfoils but with a thinner T/C (thickness/cord) ratio of 13%. This helped increase critical Mach but dramatically reduced fuel capacity, which kept it in the intercepter role (and prevented the use of wider landing gear). It was a very good interceptor . The P51 was physically larger, stronger and heavier to hold enough internal fuel for long range missions and more ordnance. Although the Spitfire could use external fuel tanks, it is the amount of internal fuel that limits fighting radius. This is because the fighter will will drop its external fuel tanks before entering combat and returning home. The last iteration of the Spitfire, the Griffon-engined Spiteful, had tapered laminar flow wings to farther increase critical mach.

All you say is correct with a few caveats. 'They' did know when Spit was designed that the thinner wing in same NACA series had less profile drag. Hard to be specific about 1934 but NACA (Prandll & TieTietjens published papers about wing section drag in compressible flow in 1934. Von Karman and Milliken were leading lights on compressibility and boundary layer behavior in 1930's fromCal Tech. I can't remember if Spit wing was NACA 2213 or 2413 (or?). Historically, Schmued called for NACA 2616 for the P-509 proposed to BPC, then NAA/NACA 45-100 (with NACA 23016 as back up). All were High Speed/Low Drag category. The 45-100 had Max T/C at 37.5%. The later XP-51F/G/J and P-51H had the NACA 66 series wih Max T/C at 50% (IIRC). The second reason for less Mach Tuck/CM change was that the movement of the Center of Pressure movement was less dramatic at Mcr.

Mr Brown, Sir, I salute you.

The USAAF was able to fix the control lock issue/tail separation with the early P-38 and P-47 fighters and the lateral control issue with the early P-51D. The latter two fighters went on to do sterling service as both escort fighters and fighter bombers.

Even then, there are a lot of things that need to be factored in. First of all, because the fighters cruised so much faster than the bombers and in order to get maximum fuel economy out of them, they had to operate in a sort of 'leapfrog' system of scheduling. An escort force would fly with them across the Channel and perhaps a short distance into Germany - even RAF Spitfires did this - before another escort group would pick them up. They would then escort them either to the target or to the next rendezvous point. Finally, the process would be reversed for the trip home. This would require a huge amount of planning. First of all, the relative economical cruise performance (speed/altitude) of the fighters v bombers had to be considered. Too slow and they'd chew up too much fuel. Leave too late and they might not make up the distance before the Luftwaffe started attacking. Next, the relative cruise performance of each fighter type was considered. Then there was the matter of weather and this played a much bigger role than almost everyone realises. Finally, where were the Luftwaffe fighter bases concentrated? Would they be ready and hiding behind the next cloud or would they be on the ground, refuelling? These are the questions mission planners sweated over. These parameters were different for all types, so a direct comparison is not always possible. For the longest range missions, there seems to be little doubt that the P-51 was the best choice and this overrides an awful lot of other detail. It just had the best range/performance of all. That is reflected in the comments of people like Don Blakeslee and 'Hub' Zemke. It was also easily good enough to take on the Luftwaffe in pretty much any other escort mission too and that is reflected in the comments of Luftwaffe pilots who fought against it. When the Mustang arrived, the others were simply gradually replaced. The P-38 - which was not a good escort fighter in Europe - was used effectively in the PR role. The P-47 gained a second life as a fighter bomber, doing ground attack work, in concert with the British Typhoon. *_"Couldn't this control reversal problem have been solved by the bombers flying at a lower altitude and maybe the escort fighters diving onto attacking fighters at a slower and shallower angle, perhaps using dive brakes if they had them?'_* Mmmm... well, it might but it doesn't make enough tactical sense to me. Never give away altitude. If we're going to stick to the famous 'Dicta Boelcke', it's worth remembering _'1. Try to secure advantages before attacking. If possible, keep the sun behind you.'_ They may not always have been able to make use of the sun but they wouldn't be sacrificing altitude. *_"This wouldn't solve the tactical Mach number either but it might just have given the bombers a better chance if the fighters could stay around longer."_* Well again, that depends on the range performance of the fighters. Each aircraft has its most efficient altitude.

Ah, good ol' embellishments during story time! EB didn't bother to mention the tactical mach number EB talks about is completely and utterly useless in reality as ZERO, well zero piston engine aircraft anyways, me262, me163 might be a different story, aircraft at the time had enough power to come even close to reaching their tactical mach numbers, so the ONLY Mach number which matter, were the critical mach numbers achieved in a DIVE. Yes, in a DIVE. The only two aircraft which could realistically hit their Critical mach numbers were the P47 and the Tempest as they were the ONLY 2 aircraft which could partially maneuver at such speeds without ripping their wings or empenage off and why P47's were routinely shooting down BF109's/190's at M0.78 and above in dives and German pilots were quickly told to NOT dive away from P47's. Spitfire could not maneuver at critical mach(like EB's story time pretends to portray), its empenage went inverted and the test pilots got damned lucky. EB also then tried to insinuate that the Spit could dive to M0.92... Uh... no it could not come even close. Said special test aircraft Spit had ***a completely different gear ratio, engine RPM limiter was removed, and special propeller*** as previous tests had shown the normal propeller stopped the aircraft cold at M ~0.86 even with RPM limiter removed a mere M0.03 higher than its critical Mach number of 0.83 where the test pilot barely survived(several others had already died in ground augured Spits, Eric Winkle Brown oh so ***bravely*** just ***FORGOT*** to mention this little basic fact) . Indeed the Spit Critical Mach number was higher but not due to an airfoil choice, but rather a wing thickness choice all by accident though it did hamper Spits range(win some lose some). Good accident to have so one does not have to speak German! It was indeed barely higher than the M0.82 critical mach of the P47. EB's stated Mach critical for P47 is just flat out wrong as the manuals even state it being higher. EB was mixing up the NUMEROUS problems P38 had with critical mach being reached and the P47 which ... did not. Maybe he was remembering the Typhoon problems in such area? Or, more likely, he is just spinning a tale to make his favorite aircraft look spiffy, not that its image needs much buffing as the Spits accolades are numerous.

Mach speed was a far more critical factor than armament, because in the case of the P38, its poor critical mach caused severe compressibility effects at the speeds it could easily reach in a steep dive - a common scenario when trying to pursue a German fighter. (the Bf 109 and FW190 both had better mach numbers than the P38). In simple terms the P38 could become uncontrollable in a high speed dive, and fly straight into the ground. Eric Brown was asked to investigate why so many P38s were crashing, and when his findings were put before Gen Doolittle the P38 was withdrawn from the bomber escort role in the ETO.

Fantastic explanations by an incredible man. While I would not seek to challenge his views or knowledge for a moment, I recall a discussion in Len Deighton's fictional "Goodbye Mickey Mouse," around the relative cost of a P47 to a P51. The suggestion was that some fighter groups were re-equipped with P51's as replacements for their P47's because the P51 was substantially cheaper to produce, albeit that with the Merlin engine it was an excellent aircraft. I've always felt that Deighton's research was pretty good so would be interested to know if anyone was aware of the relative cost issues from another source. One other point made by Brown is that in his view some P47 and P38 pilots were killed in irrecoverable dives. IMVHO, many line pilots would have inevitably and tragically been less capable in such a situation than a test pilot, particularly if focused on taking the heat from the B17's, or evading the attentions of a FW190...

The design philosophy on wings for traveling at high-subsonic speeds has changed over the years. Earlier designs often reduced the overall rate of acceleration of the air over the upper wing to delay the formation of shock waves to a higher aircraft speed. The "laminar flow" designs were useful for that. Things got ugly once the shock wave formed, though. Control surfaces behind a strong shock wave operated in an area of separated flow and had low effectiveness. Merely operating the control surface was sometimes enough to trip a shock wave. More modern "supercritical" designs are shaped to allow a weak shock wave to form on the upper wing surface and still maintain good performance and control.

Captain Eric Melrose "Winkle" Brown, CBE, DSC, AFC, Hon FRAeS[1] (21 January 1920 - 21 February 2016) was a British Royal Navy officer and test pilot who flew 487 types of aircraft, more than anyone else in history.[2][3][4] Brown holds the world record for the most aircraft carrier deck take-offs and landings performed (2,407 and 2,271 respectively)[2] and achieved several "firsts" in naval aviation, including the first landings on an aircraft carrier of a twin-engined aircraft, an aircraft with a tricycle undercarriage, a jet aircraft, and a rotary-wing aircraft. Brown flew almost every category of Royal Navy and Royal Air Force aircraft: glider, fighter, bomber, airliner, amphibian, flying boat and helicopter. During the Second World War, he flew many types of captured German, Italian, and Japanese aircraft, including new jet and rocket aircraft. He was a pioneer of jet technology into the postwar era.[5]

I respect Eric tremendously, however I am a bit confused by him calling the P47 and P38 useless. Mach limit doesn't determine if a fighter is useless or not. It determines when its time to pull out of a dive. Not all dogfights had people diving at max speeds. The P47 and P38 fly higher and faster than Spitfires and that is far more useful than dive speed. You don't need high mach limit unless you're running away or chasing someone who is running away.
