Title A Servo System Design and Simulation for Missile with Thrust Vector Control in Booster
Abstract
As to cruise missile, the ones with the help of vertical launch system could be launched in every directions, as exceptional advantages for attack and defense. Tomahawk mainly uses a turbofan for propulsion, which could not work when missile velocity is zero. In this situation, rocket booster could help in the earlier stage of missile propulsion. This paper did a research for servo system of rocket booster used in vertical launch way. In that of force lack when missile turns using air rudder, a spoiler device could make its influence, working near to nozzle, on missile for a smooth turn in a certain time. Further, this paper designed a sort of drive mechanism, drawing three dimensional paper, which could turn a spoiler in servo system. And concerning about the requirements of processing technics, the conditions of processing and the real size of standard spare parts, it drew a series of CAD drawings for machining.

1.1 课题研究背景
垂直发射的众多优点使其成为了军事中竞相研究并采用的导弹发射方式之一，其技术关键主要在于导弹能否在垂直发射的情况下实现精确控制和快速转弯。由于在垂直转弯的时候空气舵的操纵力矩不能达到要求，所以需要引入助推器，运用推力矢量技术来满足垂直转弯时需要的力矩。在助推器推力矢量系统中，伺服作动系统作为导弹控制系统的一个环节，负责执行控制系统的命令，来改变推力的大小和方向。本文研究的目的就是对某型巡航导弹助推器的伺服作动系统进行设计仿真和加工试验。
