HUD (Heads Up Display) from TXX, 1993


The F-22 will be the US Air Force's largest fighter yet, with a 842.4 sq. ft. wing area. All weapons are carried internally for stealth. Also due to the requirements of stealth, there are no vertical surfaces, which show up well on radar, so the fins are canted outward at 28 degrees. For stability, the fins will be very large, but not as large as those on the prototype. The sharp breaks or 'chines' on the sides of the nose are also due to this requirement.

The final version will have a modified tailplane, a lower profile, and wings cut off at the outer trailing edge, to reduce the formation of vortices. It will have a leading edge sweep of 42 degrees, as opposed to 48 degrees in the prototype. It will also have a lower profile and a blunter nose. There will be no air brake on production F-22s.

The unique canopy, with no spars, will be retained, giving the F- 22 unprecedented visibility for a fighter.

The large trailing edge flaps are to be modified in shape, with the inboard and outboard flaperons having constant chord (forward length). Together with the leading edge flaps, these will form a Mission Adaptive Wing (MAW) as seen on the F-16 and Eurofighter 2000. "
