U.S. Patent Specifications

Abstract

An aircraft comprises a jet propulsion plant having a jet pipe terminating in a jet nozzle for the rearward discharge of a propulsive jet stream; anchorages on the aircraft; a jet deflector comprising a canopy made of flexible metal cloth and flexible cords made of metal strands attached at their ends to the canopy and to the anchorages, and a canopy‐receiving housing on the aircraft. The canopy is foldable and unfoldable so as to be capable of being packed and stowed in the housing and of being opened up to form a chute. An axial cross‐section taken normal to a plane containing the axis of the jet stream is defined by two symmetrical arcuate portions meeting at one end on the plane at an apex and curving away from the plane one on each side thereof to edges at their other ends. Cords are attached to the apex and to the edges of the chute and are such in relation to the position of the anchorages that when the canopy is in the housing they extend from the housing to the anchorages and when the canopy is opened up they position it with the apex pointing towards and aligned with the nozzle on the plane and the concave sides of the arcuate portions facing the jet stream and the edges spaced apart by a distance greater than the transverse dimension of the jet stream measured normal to the plane.
