Web3 aug. 2015 · Thrust produced by a nozzle can be given by F T = m ˙ V e + ( p e − p 0) A e Thrust component in a nozzle can be split into two component that is pressure thrust ( ( … Nominally, the line of action of the thrust vector of a rocket nozzle passes through the vehicle's centre of mass, generating zero net moment about the mass centre. It is possible to generate pitch and yaw moments by deflecting the main rocket thrust vector so that it does not pass through the mass centre. Because the line of action is generally oriented nearly parallel to the roll axis, roll control usually requires the use of two or more separately hinged nozzles or a separate system …
