Abstract
An overexpanded thrust vector control nozzle has a converging extension section downstream of the jet exhaust stream deflecting section for defining a restriction or orifice. The orifice functions to elevate the exhaust pressure in the deflection section, which permits a reduction in nozzle size for operation at high and low altitudes. The orifice, which isolates the deflection section from outside ambient pressure, receives a deflected exhaust stream after it is turned in the direction opposite to that of the original stream deflection by the wall of the converging section. Control ports, which are adapted to communicate with a source of pressurized control fluid, are provided in the deflection section to position the exhaust stream.
