Abstract
A nozzle 16 for a turbojet is provided with a thrust deflector mechanism, downstream of the nozzle in the form of one or more target-type thrust reverser plates 18. The plate or plates 18 are movable from a stowed position into the efflux of gases issuing from the nozzle to deflect the exhaust gases and hence redirect the thrust produced by the nozzle obliquely relative to the central axis of the nozzle 16. The plate or plates 18 are mounted in a bearing for rotation about the longitudinal axis of the jet pipe. When rotated the redirected thrust is effectively rotated relative to the central axis of the nozzle. In one embodiment a pair of plates 18 is used and they can also be employed as a conventional thrust reverser.
