ABSTRACT:
In a VTOL, aircraft having pairs of angularly movable jet-engine-efflux discharging vectored thrust lift and propulsion nozzles at the under side of the fuselage, a deflector door is provided to divert the hot exhaust gases that rise toward the fuselage when the aircraft is near the ground and thereby prevent such gases from approaching the engine air intakes. The deflector door swings from a retracted position to a position in which it projects downwardly and forwardly below the fuselage and it has edge blowing slots through which bleed air from the engine is blown in a downward and forward direction with a lateral fan-wise spread. This door also serves duty as an airbrake.
