Abstract
A boundary layer thrust vector control nozzle (10) has a housing (18), the aft end of which has attached a control vane assembly (12). The control vane assembly includes two brackets (78, 80) which receive two vanes (86,88) such that the vanes are in spaced parallel relationship and extend across the exhaust opening. The vanes have equal but opposite angles of attack and are adapted to generate large side forces in a perpendicular plane and small side forces in a plane parallel to the vanes. The nozzle includes four sets of control ports (44, 46) for deflecting an exhaust plume to produce the large and small side forces also to produce significant roll moments.
