ABSTRACT:
An exhaust nozzle for a gas turbine engine comprising a duct 17(c) and a mechanism for varying the geometry and area of the nozzle. The mechanism includes a plurality of movable flaps 38 which in at least one position define a convergent part of the nozzle. Upstream of the flaps 38 there is provided one or more outwardly directed openings 59 in the wall of the duct 17(c) and a pair of mutually confronting doors 61 which rotate about an axis transverse to the length of the duct. The doors 61 are located relative to the duct 17(c), the openings 59 and the flaps 38, so that in a first position, the doors 61 obturate the one or more openings 59 and provide a substantially unrestricted flow path through the nozzle. The doors are movable to a thrust reverse position where they uncover the said openings 59 and cooperate with the flaps 38, when the flaps 38 are in a convergent position, so that the flaps 38, together with the doors 61 provide deflecting surfaces that redirect the flow of gases out through the said openings.
