ABSTRACT:
A combination air brake and engine shield for a jet powered aircraft. A hydraulically operated, hinged shield member, shaped so as to conform to the surface of the aircraft fuselage when in its retracted position, may be swung outwardly therefrom so as to be disposed in front of the air intake of the jet engine powering the craft, to thereby divert any foreign objects from being drawn into the intake and damaging the engine. The same arrangement may also serve as an air brake to effect deceleration of the aircraft. Spring loaded louvers are provided in the shield to permit sufficient air to reach the engine such that problems due to cavitation are avoided.
