ABSTRACT:           

            Thrust vector control (TVC) methods were developed as an alternative to aerodynamic control surfaces for missiles, which suffered from poor pitch- over characteristics in launching stage. TVC system, can allow the missile to turn quickly and stably in any direction by deflecting the nozzle exhaust gas irrespective of the missile speed. A jet vane is one of such devices, used for thrust vectoring. An effort has been made to evolve a methodology that can be used to develop a jet vane, that is lighter in weight and / or smaller in size for a given control force. Computations have been performed to analyze the jet vane at high temperatures at different angles of attack.

            The aerodynamic performance of a jet vane has also been determined at Mach number 2 in a supersonic wind tunnel at ambient conditions. In another experimental set up the jet vane erosion has been determined by placing a mild steel jet vane in the stream of exhaust gases at different angles of attack.

KERWORDS: Thurst Vector Control (TVC), Nozzle exhaust,  Jet Vane, Angles of Attack.
