The dynamics of opening a missile bay door and dropping a missile into a supersonic airstream must be interesting. I'm guessing there are some trade secrets around that. Interesting facts: The first jet fighter with a known supercruise capability was the YF-17 prototype. Even the A-12 could not super cruise that I know of. Some older aircraft might have been able to supercruise by using afterburner to become supersonic, and then throttling back. Some notable planes that were pretty fast: XFCU-8 Crusader III prototype, the F-106, the YF-23 prototype was reputed to be much faster than the F-22. It's speed is still classified, probably just to protect the reputation of the US Air Force. The F-111 was damn fast, faster than an F-15 at sea level, though in many ways an overly ambitious, problematic aircraft from a previous generation. A dangerous plane. My opinion - the F-35 is garbage but has good avionics and fancy though highly toxic radar absorbing paint. Speed has actually been downrated because they will literally burn their own tails off. I do not believe they are even supersonic at this point. The primary reason for the f-35s performance is a super rated afterburner which has been tacked on to it. Otherwise it has no more real thrust than the F-22 engine. It's just a feature to impress generals at air shows by burning up all it's fuel in a few minutes. But they are right that it's main power is just networking, radar and fancy missiles. The basic airframe is garbage though.

@ImperiumLibertas

I'm sorry but the F-35 is not garbage. If you expect the F-35 to fight like an F-16 then yes it will perform poorly. That is not it's role or the tactics that would be applied when flying the bird. You can't judge a fish by it's ability to climb trees. The F-35 is the most integrated airframe to ever fly. The amount of situational awareness it gives the pilot is unrivaled. This allows the pilot to make the best decision at all times with the best information available. SEED and stealthy A2G will be it's primary tasks. Additionally it can feed data back to the AWACS without using it's radar. A typical F-35 A2A engagement might look something like this - F-35 uses passive search to identify enemy aircraft - F-35 sends bandit location data via datalink to AWACS - AWACS commands F-15EX to fire AIM-260 missle from over 100 miles away - AWACS provides guidance into the AO - AIM-260 recieves updated location via F-35 datalink and it's onboard radar for terminal guidance - Splash bandit By the time the bandit knows it's being targeted it's too late to react. Additionally the F-35 could continue to do a strike or SEED mission without missing a step. Fifth and sixth generation air warfare is going to be wild for anyone unable to keep up. It's a completely different way of thinking about air combat. I didn't even mention loitering munitions for air superiority and area denial or autonomous drone swarms used to overwhelm anti air defenses.

Actually the Concorde engineers did call a function of the Concorde Supercruise. I am talking here of the Ability to stay supersonic without using the afterburneres. This function is also called Ramp smoothing which reduces the air intake speed to a subsonic speed by using small ramps inside the intakes. This only worked above mach 1.3 explaining why it needed afterburners to go supersonic in the first place...

No mention of the first military aircraft capable of supercruise to go into service. The English Electric Lightning which went into service back in 1959

@bengrogan9710

3 жыл бұрын

That's because all the in service variants required afterburner to maintain supersonic speed The initial prototype was shown to cruise at 1.02 in a clean configuration only - The 1st production variant weighed more and has the parasite drag of the weapons which reduced sustained cruise to 0.94 later variants reduced this further with the increased belly tankage reducing the non-after-burning cruise with weapons to 0.91 This is before considering that super-cruise as a concept is to put you above the peak of transonic drag, where as that places you directly AT said peak

Btw. the MiG-29A/MiG-29G can supercruise, too, without afterburner. Mach 1.3 @ 10000m, likely clean. It can enter supercruise without afterburner by climbing above that altitude and then go into a shallow dive. Just fyi.

Great video, you explained a lot. But it also reminded me of what could have been. The YF-12 interceptor would not have been able to "supercruise" because it used an afterburner/ramjet feature at cruise, but its performance would have been phenomenal (superduper cruise?). Based on the SR-71 range of over 2,000 miles at Mach 3.2 , the YF-12 would dwarf any of these modern planes. How long can they supercruise at only Mach 1.5? Add 4 AIM-54 missiles with modern guidance systems, launched at Mach 3 and 80,000 feet and the threat would have been awesome. Increase its stealth and electronics and a modern YF-12 would be very impressive.

Afterburners don't typically 'double the engine thrust'. Engine thrust usually increases about 40 to 50 percent, give or take, for most fighter engines. Super cruise engines will burn less fuel when flying at super sonic speeds than after-burning equivalents. However at sub sonic speeds they tend to burn more fuel than engines that do not super cruise. Ironically they also burn a little more fuel in afterburner as well. While the f-35 doesn't super-cruise its engine is more efficient than the f-22 engine from which it was derived, when flying at sub sonic speeds. As a result the f-35 has much more range than the f-22, for this and other reasons. The f-22 apparently can only super-cruise for a limited period of time, which limits its capability in many situations. It's a nice capability to have, but like anything it has limitations.

Thank you for this informative video! Here is another enlightening comment on the subject: Everest E. Riccioni , Col . USAF 2/10/2005 8:48:59 PM " The F-22 has not yet demonstrated effective supersonic cruise The USAF has never appreciated that speed without persistence is meaningless. Proof� Six USAF aircraft capable of Mach 2.2 never exceeded 1.4 Mach in combat over North Vietnam in 10 years of war, in hundreds of thousands of sorties. The F-15 has never demonstrated its performance guarantee of Mach 2.5 flight in a combat configuration on a realistic combat mission profile. The USAF has the wrong definition of supercruise �(supersonic flight in turbojet thrust, i.e. without using an afterburner. Cruise means covering distance efficiently. Fighters with wings properly sized for subsonic maneuver achieve efficient supersonic flight at altitudes of 60,000 feet requiring partial afterburning thrust. This may be unknown to the testers since the test program limits testing to below 50,000. The proper cruise condition may remain unknown. All supercruisers cruise at very high altitudes using some afterburning (i.e. ramjet) thrust-MiG-31, SR-71, as did the many designs that I have studied, generated, or supervised. (Detailed aerodynamic-thermodynamic analysis is available upon request.) The GAO report that the F-22 has demonstrated supercruise is specious and misleading. The reports have merely stated that the F�22 has demonstrated 1.6 Mach flight speeds in pure turbojet (dry) thrust. No report of distance traveled or persistence at those speeds was made. Supersonic speeds in dry thrust bode well, but this capability is not sufficient to achieve supercruise. Proper data are global radius of action and global persistence plots as functions of speed and altitude, for rational missions. These data must be then compared to those of the F-15 and the ancient F-104-19 to establish progress. For example , the 40 year old F-104A-19 has twice the supersonic radius of the 20 year old F-15C at 1.7 Mach, and out-accelerates it at Mach 2.2.Compare! In comparison lies the proof of progress.

I was under the impression that the EE Lightning could supercruise. In review, this comes down to wether people tightly define as per the US originators definition, or more loosely supersonic without afterburning. This gets into a lot of beer argument at the bar. I shall take a slightly different view. I love the Lightning. But the ability to fly supersonic without lighting up the afterburners was good because that plane drinks fuel at ungodly rates, the pilots need to have a 3rd sense for knowing where the nearest in flight refueling tanker is, and the fuel gauge is monitored more than the early radar :P Super cruise is a very interesting subject.

I have one thing to say just on the end of the video - energy, and talk of merge. And this is only my laymens view, so not based on absolutely solid science or evidence. But high speed / energy at high altitudes, seems to be a misnomer. Aircraft with wing loading, especially high wing loading - have limited lift at high altitude. Its worth nothing that in NATO tests, no 'fighter' did well against lumbering Vulcan bombers in tests at 45,000 feet. The enormous wing of the Vulcan gave it the ability to still manouver. The fighters were unable to 'turn' at these altitudes in the same way. (In beyond visual range with modern missiles the point is moot, Vulcan dies..) Most dogfighting pre/merge/post merge won't be at high altitude, or if it is, it will be very high speed/low G.. - probably with hard drops into lower altitude..

Concorde is also considered a supercruising aircraft. The reality is that most supercruise capable aircraft use the afterburner briefly to go supersonic, then throttle back and accelerate to higher Mach. Supercruise is generally defined as sustaining Mach 1 or greater. Another thing you mentioned is definitions. The US defines supercruise as Mach 1.5 specifically. Probably because achieving Mach 1 speeds without afterburner really isn't that remarkable. After all, the old EE lightning did it.

And it might fit someone's definition, as it was very capable within certain tick boxes. Outside of those boxes, it wasn't capable. Phantom came along and had a much wider capability (and was a tremendous plane in its own right...) But it was built as an interceptor, with rate of climb and high speed being doctrinal. If you examine it critically, the RAF never had enough QRA available against any serious raiders, and lack of range was an issue in this area all the way back to point defense spitfire and hurricane. And after the '57 idiotic defense white paper, which basically ruined manned aircraft development in the UK, Lightning was under developed though its whole program. Even with that, there are some things only Lightning could do in its time, and it took some tremendous planes to eventually come and do what it did, only a lot better. It generally left the US century series in its wake. many things are trade offs, especially in old gen aircraft.

I am however, of the opinion that aircraft like gripen that cruise at Mach 1.2 clean are probably not going to be supercruising in actual combat.

Raptors can supercruise at Mach 1.82, but most pilots haven't seen that on mil power. More like Mach 1.5 operationally. Interesting stuff about the Lightning.

I don't think people really realise that at high altitude, a lot of engines don't work that well, the air is damn thin, and beyond that a lot of wings don't work well. No one will be pulling 9 G turns at 50,000feet. And when people pull sustained ... say 2g, as much as you may turn, you are burning energy and drag to make that turn and your stall speed is likely a lot higher than at lower down altitudes. In the end most actual dogfighting will drop to middle or low altitude where engines and wings .. work. There is an argument to make specific high altitude missile platforms instead of some of this lunacy. Just build a platform that cruises at 70,000, carries shitloads of evil missiles, ECM and its own AWACS ability, and dominate the area. In terms of the UK, instead of burning Eurofighter airframe hours chasing dumb bear bomber intrusion it would be better. Leave the dogfighting and dancing to the fighter boys.

Very interesting video, but regarding Concorde I want to put some additional information, since the supercruise capability at M2 was a crucial design requirement, being essential to fulfill the transatlantic mission. If I understood your supercruise definition correctly, i.e. if supercruise must only be achieved and maintained without the use of re-heats, - then you are right - Concorde could not practically operate in this way. Nevertheless, a differing supercruise definition might allow to cover an enhanced supercruise regime, e.g. respecting the case of Concorde. Concorde used re-heats, but only for about 50 - 70 seconds during take-off and then again for 10 - max. 15 minutes for accelerating from M0.95 through the transonic region, resp. partly for climbing up to M1.7, just enough to build up sufficient pre-compression inside the unique air intake system. At supercruise, the intakes provided 7.3:1 in front of the first compressor stage, thus enabling 82:1 in the Olympus turbojets. During the climb phase above M1.7 - i.e. even after the re-heats were cutoff - Concorde still continued accelerating. Supercruise potential: The engine power even had to be reduced to prevent the airframe from thermal overheating caused by friction. Regarding the thermal barrier (127°C), Concorde usually supercruised at M2.02 (M2.04). By this values the thermal efficiency of the propulsion unit was approx. 43%. Actually, I don’t know any aircraft which was or is capable to supercruise under comparable conditions as Concorde did.

The XB70 can supercruse at 50% engine powet at M2. While concorde is still sligtly better (about 48% or something, dont bother calculating it now). The thermal efficency increase with speed for a 0 bypass engine, so valkyre would proboly have higher efficency at top speed. For 0 bypass engine there is really not much beside speed that effect efficency. The B1A probobally outpreforme concorde as well in that regard, also being a turbonfan probobly do that prior to M2

@@matsv201 Thank you for your reply! Yes, in calculation speed is a driving factor for efficiency. But beside this fact, I think another important circumstance comes by the design attunement between the airframe, air intakes, engines and nozzles. The cruising speed of Concorde was limited due thermal heating (max. allowed 127°C), since an aluminum alloy was widely used for the airframe. The XB-70 was mainly made of stainless-steel material to sustain the high skin temperatures at M3. This measure made the airplane relatively heavy - for this and probably for other reasons it required 6 turbojets. It also had only two main intakes to feed all their engines - which possibly made the airflow relatively complicated to control and not so efficient as it could have been when using a separate intake for each engine. I think one main secret, what made Concorde so efficient (especially at her time and beyond), was its highly advanced and digitally controlled intake system, which also enabled each engine to operate individually at its best operating condition. An interesting fact is, that even for the younger PANAVIA Tornado, the principal technology of the air intake design and digital control system - as used by Concorde - should have been implemented to improve the engine control in different flight operating conditions and thus to enable the Tornado a better and safer supercruise performance. en.wikipedia.org/wiki/Panavia_Tornado It would be interesting to know the impact in efficiency which is derived by the air intakes systems used in other modern supersonic aircrafts.

​@@karlskrivanek5687 "(max. allowed 127°C), since an aluminum alloy was widely used for the airframe." That is not the reason. The reason is that the air heat up when its compressed by the engine. The amount it heat is relative to the absolute temperature at the intake, so if it becomes to hot, the engines will be unable to add more fuel before the turbine blades melt. There for it need a intake temperature limit. "This measure made the airplane relatively heavy" One would believe that, but that is actually not quite true. XB70 have a empty to full factor of 47% while Concorde have one of 42%. While the steel ad a bit of weight, its far less than one might believe. Also the use of canard and a few other features made XB70 a bit more efficient, also alowed it to use more lift during takeoff. " for this and probably for other reasons it required 6 turbojets" Its actually not the case. The jets on XB70 is far smaller than that of Concorde. The total thrust is actually less even if XB70 is heavier. Even the B1A have considerably lower thrust than Concorde despite being quite a bit heavier. "I think one main secret, what made Concorde so efficient (especially at her time and beyond), " I would say rather that there was a dude sitting at a control panel handling the engines, compare to the 737 that was launched at the same time that did it totally automatically. Concorde actually have 5 seats in the cockpit. One capten, one fist officer, one navigator, one engineer and one instructor seat (only used in certification flights). Behind them was the electronics bay, in steed of under the pilot as in most aircraft at the time. This took up the same space as 12 passenger. Not only that. Most of the space below the floor was either taken up by wheels or by fuel. So there was hardy any cargo space. So most of the cargo was stored in a section int he aft of the aircraft, taking the same space as 12 more seats. This is actually a major contributor to why its so thirsty, because fuel is counted peer seat. If it was 5 seats wide, the avionic bay would fit under the cockpit, also the luggage, and there would still be space for fuel, as well as adding. That would pretty much cut fuel use by 60% "It would be interesting to know the impact in efficiency which is derived by the air intakes systems used in other modern supersonic aircrafts." Well a modern supersonic airliner would use medium bypass engines... like the Boom and Spike is planed to do. This totally of set the math. My calculation estimate that the engine of Boom and Spike have a specific fuel consumption of 28g/kN*s while Concorde have 34. Concords official drag ratio is 7.14, while i calculated Boom to 11.7 and Spike to 10.7. I done this by reverse engineering there numbers, so if there numbers are of, so are mine. Combine it and there is a large advantage for the newer planes, while the advantages become smaler when taking into. anyway, Concorde is so fuel laydend, so even a minor improvement in fuel consumption will give a large effect on the over all aircraft size.

Would have loved to see the performance of the YF-23 if it would have gone into production. Thank you for the video.

how sr71 supposed to use afterburner in ramjet mode that already used to cruise for longtime supersonic flight?????please somebody help im cnfused😮

The EEL Lightning was the first jet to supercruise

So do aircraft capable of supercruise need to use the afterburner to go past Mach 1? And when does transonic end, at Mach 1, or later around 1.05?

@matsv201

It really neved does. It also depends on the shape of the aircraft. Byt by say 1.3 the effect start getting neglectable. You can design a aircraft to to have a smalet or wider transonic range. A example of a plane that suposed had a very narrow range was the sonic cruiser, hence going all the way ro 0.95 in cruise. Most supersonic aircraft try to have the wide range so they can go over it with a lowet peak.

The old NK-32, installed on the original Tu-160(years 1987 - 1994) is widely known as the most powerful engine of a combat aircraft in the world. The NK-32 engines, originally installed on the Tu-160, had a mass of 3.7 tons with a length of 7.5 meters and a diameter of 1.8 meters. The power plant is capable of developing thrust up to 14 thousand kilograms-force (137.3 kilonewtons) and 25 thousand kilograms-force in afterburner mode. Tu -160M(year 2018) is ​​a completely different machine. Outwardly everything looks the same, but the engine and flight range, power and everything is different. Tu-160M(maximum take off weight: 275 tonnes) has NK-32-02 engines that includes new blades for the compressor and turbine, as well as more efficient cooling. The aircraft is capable of reaching supersonic speed(2.2 thousand km / h) in afterburner mode and holding it for 45 minutes. The main and back-up electronic systems of the NK-32-02 engine should provide a bomber flight for up to 30 hours. Fuel supply and hydromechanical regulation systems must operate at near-zero and negative overloads up to 2.7 g and at temperatures from -60 to +50 degrees Celsius. The minimum service life of the product should be 12 years, with the possibility of extending the service life to 21 years. Finally, the NK-32-02 engine must be resistant to the effects of the damaging factors of nuclear weapons.

as you say going fast is safer but turning is more difficult it is easy to generate high G and that is what is needed to force the missile to use high G as the intercept point moves around in sky. I think some missiles don't use lead pursuit while they are traveling to the target since the pilot then can make the missile start maneuvering loosing speed, but the missile need to use it when closer or risk missing. So defending pilot need not start manuver immediately and he has his countermeasures onboard chaff/flare and jammer ( which he can flip on and off if the missile has home on jam capability ) and if he can do the doppler notch perfectly it is nice but might die trying. it differs between pilots how many G they can take and for how long should affect what the pilot tries to do. if the two sides merge, and have similar performance, you might have to slow down to corner speed to make the sharpest most efficient turn you can make. This is not a fixed number but depends on how loaded the aircraft is with fuel and weapons. You seen WWII fighters drop their droptanks as the fight starts. Or multirole fighter doing air-to-ground mission should need to jettison all the bombs to be able to win the dogfight. There is also another speed called corner velocity but is unclear to me what it is. It is a higher speed, maybe it is the highest speed at which you still can still generate maximum degrees per second in a turn. The addition of offbore weapons might also affect if the pilot wants to slow down or not. So I want to hear more about tactics and speed. Have anything changed the last 20 years? Are the latest versions of missiles basically the same as the first version or have they gotten a brain upgrade?

question : if the the drag becomes normal after the barrier then why dont planes use the afterburner to get to mach 1.1 and then use dry thrust

@Millennium7HistoryTech

The drag coefficient is lower, but the drag keeps rising, albeit at a lower pace because ... the coefficient is lower. To accelerate from M 0.7 to M 1.2 (0.5M delta V) requires a larger impulse than from M 1 to M 1.5, same delta V but lower impulse.

I disagree that the Concorde was "not technically a supercruise aircraft". It was able to cruise at M2 for multiple hours without afterburner. The fact that it needed a touch of reheat to accelerate through M1 doesn't detract from that in any way. I suspect that plenty of the other aircraft on this list need either afterburner or a "dive-climb" acceleration profile to punch through the transonic in all but the cleanest configurations.

But what is supercruise used for spaciffically

Πότε θα θέλατε να μας πείτε για το ρωσικό δόγμα στην πολεμική αεροπορία??

Concorde required after burners for take off and to break Mach 1. However, it could supercruise at Mach 2, at 60000 feet.

It's a factor. More important than starting speed is starting altitude. Fighters that can climb and build great speed while climbing stand a better chance than not. You'll light everything up, drop stuff you can afford to drop, climb as fast and as energy efficient as possible and try to calculate optimal launch position. If engaging at BVLOS you'll never engage at military thrust, supercruise or not. Unless you want to die that is. Supercruise makes things easier. Patrol range, starting speed etc. But if you have fuel to spare, power and a fast fighter (high T/W, low loading), you'll probably still come out on top, given similar metrics.

Starting altitude is in a way the same as speed. Unfortunately high altitude also makes you an exelent target for radar, ground baset irst systems. So there are advantages and disadvantages with it depending on plane and mission.

Sure. But this is clearly talk about intercept with air to air. And no. Speed is not the same as altitude. In physics yes. In this reality no. Because you cannot compensate in starting speed for what the missile gains in thin air. Your MAR is far larger for someone engaging you at high altitude than low.
