发射宇宙飞船用的多数运载工具需要通过某些导航或控制以便达到所需的飞行轨道。为了得到这种控制,固体火箭运载工具配备有推力方向控制系统。已经应用了机械的和空气动力的技术来修正发动机推力的方向并提供所需的控制力。本文只限于论述这样的推力方向控制系统,即给发动机推力附加一个侧向力,这个侧向力对飞行器的重心产生一力矩以进行控制。本文对各种推力向量控制系统作了简要的评述,而对柔性接头 Most vehicles used to launch a spacecraft require some navigation or control to achieve the desired flight path. In order to obtain such control, the solid rocket vehicle is equipped with a thrust direction control system. Mechanical and aerodynamic techniques have been applied to correct the direction of engine thrust and provide the required control. This article is limited to discussing thrust control systems in which a lateral force is added to the engine thrust that produces a moment in the center of gravity of the aircraft to control. In this paper, a brief review of various thrust vector control systems is given, while for flexible joints
