ABSTRACT:
An exhaust nozzle (12) for providing both yaw and pitch thrust vectoring includes an upper flap assembly (18) and a lower flap assembly (20). Each flap assembly (18, 20) includes a forward stub flap (51, 53) with lateral hinges (32, 34) and a plurality of individual flap sections (52) extending longitudinally downstream and adjacently engaged for defining the upper and lower gas flow boundaries. The forward end of each flap section (52) is pivoted vertically (54) in the same plane as vertical sidewall hinges (48, 50). Yaw thrust vectoring is achieved by pivoting the sections (52) and sidewalls (22, 24), while pitch thrust vectoring is achieved by moving the flap assemblies (18, 20) about the respective forward hinges (32, 34).
