Abstract
Aircraft for short landing and takeoff distance is provided with engines providing jet flow above the wing. Flap structure aft of the engine can be swung up on an axis near the trailing wing edge, to deflect jet flow in down direction.
Claims4
In an airplane, the improvement for obtaining short takeoff and landing distance, comprising the combination of a jet flow emitting engine mounted on the upper side of a wing of the aircraft and in forward position so that the jet as rearwardly directed by the engine passes over and above the wing;
- and
- the wing being constructed to have flap means in the rear of the engine, the flap means being pivotable on an axis adjacent the trailing edge of the wing so that the front portion of the flap means swings up for being positionable in the range of the jet flow of the engine to obtain jet deflection in down direction along the lower side of the swung up flap means.
