“Sure these have influence. But increased thrust and less drag from other areas have influence too. “

not so true, sometimes the thrust increase dont have influence in the max/top performances of the aircraft, for example the increase of the thrust in the f15a to c didnt increase the max speed

and of course the f22 will have better supersonic performance than the f15, or at least thats what i hope, but dont know if will have other better performances like the climb rate

guess that some guys thinks that with the right inlet you can put anything as engine, thats not true

i think that some of you guys are confusing the things, the engine still produce the energy to impulse the plane at supersonic, but that energy is turned in others, that is energy conservation, also the inlet velocity cant be counted as impulse

the outlet velocity also limits the impulse at high speeds, to have a impulse you must have a difference with the enviorement airspeed, so there is a lot of the performance to outlet to care

high bypass turbofans have bad performance over ABs because at such air temperature and airflow speed the combustion is poor, if you take the same compressor area of a TF and TB you have that most of the air that reach AB in TF have better temperature and pressure than the bypass swiched, but i dont know if you are comparing dry Tjs with Tfs-ABs, of course at low level the Abs for botrh works nicely, of cours eppl can come with the elecronics and all that, but realy that isnt a factor to measure

as is clear, the air inlet speed increase a lot at supersonic also increasing the pressure over the compressor, so we must clarify between thermodynamics limits and structural ones, in which variable inlets helps to reduce the compressor pressure

actually the variable bypass engines were intented to work as high bypass Tf at low speed/heigh and as a complete Tj at high speed/heigh

OMG, when the ppl talks about TVCs on Su-30s then the TVCs arent used in dogfight velocities, but when the ppl is about the F22, then is used at 400 knots, lol, TVCs dont have any effect at such velocities, yes at very low ones are nice , but the USAF really cares a sh*t

the VISTA is a special case, one thing is to have a mechanical forced AoA and othe an aerdynamic AoA

the ppl overrate the things , the aerospacial industry isnt a sci-fi one, and ppl reach conclusions like to say that TVCs will overcome the aerodynamics features of a plane completelly, i wonder to know why lookheed use TVCs and also these huge fins in the f22s :rolleyes:

sens, i like that show -Zim invader-, whats the problem??, but man just try to stop whining like a old guy, and not im still not married, still enjoining the life 😀

SOC, the 16 was choiced because it was better, period, the performances for the USAF flight regime were pretty better to the 16 in which it just had better inst and sustained turn in the speeds in which usaf care, the losers are crying saying “ahh was by the f100”, if nortrop would knew that the engine would be a problem, tyhey wouldnt bother with the f404, thats only to fill something in “f17 glory” books, lol

……the B2, lol, yes the plane was designed to pull 9gs, WTF!!?? :rolleyes:

the TVCs are not used as “turners” in close combat, at highers speeds are only used to correction of crusier regimen

the 16 is limited to 25 AoAs due the bad unstable design above that is dangerous to fly it

anyway, i think that the topic is changing from the original meaning, so believe what you like

man, is 25 AoA, dont remember, but guess that the data comes actually from the northrop pilot reports

lol, and now SOC

ok SOC i really dont care about the a12, etc,also i wont discuss about how was the test -in which for example the 9gs requirements werent there to test planes- and how the 22 was “improved”, just tell me the f23 max AoA wasnt 25º???, im pretty sure about that, thereare also myths about it, supossely the 23 could reach SC M1.8, but are stimations, in the tests the max SC was 1.4, the ppl is somewhat romantic with the 23, but the design was a crap, and thats the reason why wasnt choiced

ahh again with the sources game, go ask that from anyone, i dont have time with such stuff, i only say what i know, not here to discuss “mrX said that”, not “mr Y said that”, what a crap :rolleyes:

anyway if i remember well it just reached a max AoA of 25º -poor AoA-, but it turn in supersonic was better than any 4th gen plane
