An engine nozzle arrangement for an aircraft comprising:
- a nozzle for hot exhaust gases,
- a shroud for the stream of hot exhaust gases emerging from the exhaust nozzle,
- the shroud including means providing an intake for a boundary layer of air for cooling the stream of exhaust gases, said shroud comprising two pairs of plates, one pair of said plates located upstream of the other pair of said plates, said one pair of said plates comprising closeable blocking doors for providing reverse thrust when closed and said other pair of said plates angularly moveable with respect to an axis of said nozzle for altering direction of said exhaust gases and providing pitch control of said aircraft.
An engine nozzle arrangement for an aircraft comprising:
- a nozzle for hot exhaust gases,
- a shroud for the hot exhaust nozzle, and
- at least one pair of vectoring plates for controlling the direction of the hot exhaust stream, said shroud comprising two pairs of plates, one pair of said plates located upstream of the other pair of said plates, said one pair of said plates comprising closeable blocking doors for providing reverse thrust when closed and said other pair of said plates angularly moveable with respect to an axis of said nozzle for altering direction of said exhaust gases and providing pitch control of said aircraft.
