A method of designing optimum wall contour for an supersonic exhaust nozzle is dealt with in this article. Through the adoption of this method, there will be obtained the optimum wall contour of an exhaust nozzle to yield maximum thrust under given nozzle length, ambient pressure, throat area ...
A method and apparatus are disclosed for spoiling thrust from combustion gases discharged from an aircraft gas turbine engine at ground idle operating condition. The method comprises the step of positioning a secondary exhaust flap of the exhaust nozzle to form a diffuser for the combustion gases at...
Independent actuation means are provided to rotate the extension arms and the shells, thereby enabling adjustment of the thrust-vector angle or the exhaust area of the nozzle.doi:US6938408 B2Lair, Jean-pierreUSUS6938408 * Mar 5, 2003 Sep 6, 2005 Propulsion Vectoring, L.P. Thrust vectoring ...

Turbojet subsonic–sonic nozzles are devices that accelerate the hot gas incoming from the turbine by reducing the output area, generating more thrust. These devices are usually designed to optimally expand the gas at a particular operating point. The optimum expansion occurs when the aeroengine e...
