ABSTRACT:
A variable geometry ejector nozzle for a gas turbine aero engine, in which a primary nozzle and convergent throat is defined by a pair of mutually confronting flaps 30 which are of corrugated form and have slots in them, and a pair of corrugated fairing flaps 33. The fairing flaps 33 are mounted on pivotal links 31 which also carry a pair of flaps 32 that define part of the downstream boundary of the nozzle flow path. A pair of outer flaps 35 interconnect the upstream ends to the flaps 33 to the downstream ends of the flaps 32. To define an ejector nozzle, the flaps 30 are rotated to define in appropriate area throat and the flaps 32,33 and 35 are swung bodily outward to form an air intake scoop 38. The flaps 30 and 33 can be rotated to a position where they form a thrust reverser to deflect gases flowing through the nozzle out through outlets 29.
