F-22 Loadout

[Der Zeitgeist]

Is there any reason the F-22 doesn't have the flank/afterburner speed setting? It seems as if the "full" setting actually uses the fuel flow of a running afterburner.

Yes the reason the AB setting is missing is because the F-22 doesn't use AB for cruise, only acceleration/climb/dogfighting. We should probably expand our propulsion model down the road, but have a bunch of other things we want to do first.

Having a fixed and inefficient 'stealth' jet intake and duct has a nasty effect on the F-22's thrust/SFC. Static military thrust at SL is supposedly 25000lb and SFC is probably (no firm stats) 0.76. Adjusting for altitude and Mach speed (yes, we actually do that in the sim, pretty neat huh!) the military thrust is 10083lb and SFC 1.32 at 36k ft. Public sources suggest that the F-22 can only spend limited time at 100% mil/supercruise and guess we discovered there's a reason for that.

Oh and thrust for the F119-PW-100 when installed in the F-22, at full throttle (650kt) at sea level, is 16764lb. SFC is 1.04. We adjust thrust and SFC depending both on altitude and Mach speed, i.e. Thrust / (1 + Constant * Mach) * Density. Pretty complex stuff.

Thanks! [8D]

Thanks for doing this. dIdn't meant to distract you from the important stuff. ;-P
