Abstract
A variable geometry nozzle for a gas turbine engine in which a circumferential array of flaps are pivotally connected to the engine by their upstream ends, the flaps comprising interdigitated flexible and rigid flaps. The geometry of the nozzle is varied by drawing together the side edges of adjacent flexible flaps which causes pivoting of both the rigid and flexible flaps and a change in the curvature of the flexible flaps. The rigid flaps seal the spaces between the side edges of adjacent flexible flaps. A modification is shown using auxiliary radially outwardly flared flaps to provide convergent divergent geometry.
