Beyond Visual Range Combat

Study performed by Britain's DERA, or the Defense Evaluation andResearch Agency. The percentage is the theoretical win percentageagainst a Su-35 Super Flanker. The most imperative data is thecomparison between the US current air superiority fighter in the F-15 andthe F-22. There is some debate in the Typhoon (Eurofighter) and Rafalenumbers, due to the fact that the typhoon was chosen over the Rafale bythe British.

HISTORY

Lockheed-Martin YF-22 Northrop-Grumman YF-23

RFP:

Air superiority Increase combat radius

Supersonic cruise Reasonable price

Stealth Takeoff and Landing in 2000 ft

Evolution from YF-22 to F-22Wing

– LE sweep from 48 on the prototype to42 degrees on the F-22

– Wingspan increased from

– TE changes for lower operability

Fuselage

– Canopy moved forward and intakemoved rearward for increased visibility,structural strength and betterperformance

– Removal of airbrake

Tail

– Vertical tail size reduced 20%

• Initial tail volume due to concernsover spin problems

• Spin problems never materializedand the volume was reduced

Thrust Vectoring

X-31 program looked into thrust vectoring that produce high pitch rate.
