He asked for my opinion, I never claimed it was the USAF’s opinion of “super cruise”. The F-22 can, however, cruise at 1.5 mach with the throttle dialed back and up to 1.82+ on full dry thrust.
The Eurofighter fits their definition of supercruise, which was to simply exceed the speed of sound without afterburner… which is something they’ve been doing for quite some time already with the Lightning and now also with the Eurofighter, no surprise. Most modern fighters can do that.
I have the report showing various engine configuration options and the differences in performance already I don’t need to see the consumption data for the engine that fit all the arbitrary expectations made by the consortium.
No I mean aircraft fuel consumption.
Optimal cruise speed at 3 drag indexes, are never more fhan 0.65kg/s at any altitude. Usually about 0.5kg/s
Worst case being sea level, high drag index… of course,
Right and optimal consumption at supersonic cruise conditions could be better if 40% of intake air wasn’t subsonic air that needed to be accelerated again by the core volume as it goes through the nozzle.
Too little bypass and the efficiency of the motor due to temps and other issues goes down as well. There is a better ratio for super cruise.
This is a repeat convo, I’ve delved into it multiple times before. TL;DR the bypass ratio is not optimized for it compared to peers and there isn’t sufficient dry thrust to push it out of the wave drag envelope, so it isn’t possible to pull the throttle back into a cruise setting and save fuel like the F-22 does.
How is the debate happening again… The Typhoon can supercruise. This is a fact… I have no idea why certain people refuse to accept that fact. Heck. according to Priamry sources, the supercruise speed in-game is underperforming by around Mach 0.1-0.15
The “Debate” is happening again because Fireball in all his infinite wisdom has goaded MiG back into it. When will people learn not to start arguments again over stuff that’s already been dis/proved a few times now. It’s over. Honestly.
shouldnt it top out at 1.4 with a light armament? and slow acceleration does make sense, dont they usually just go on a low afterburner mode to push it up to speed?
