本报告是用于火箭、特别是战术导弹方向控制的推力矢量控制方法的综述。与采用气动控制面的系统不同,推力矢量控制系统不仅在高空而且在低速情况下(比如在起飞后的即刻)都是完全有效的。这些方法基本上可以分为三类,即;1、借助于机械装置使喷管内喷气偏转;2、二次液体或气体注射以及3、可动喷管。目前较感兴趣的是以第三类为基础的一些方法,因为技术的发展已经有可能得到合适的高温和高压持久密封的材料。
This report provides an overview of thrust vector control methods for the direction control of rockets, especially tactical missiles. Unlike systems with pneumatic control surfaces, thrust vector control systems are fully effective not only at high altitude but also at low speeds, such as immediately after take-off. These methods can basically be divided into three categories, namely; 1, by means of mechanical means to deflect the nozzle jet; 2, secondary liquid or gas injection and 3, movable nozzle. Of current interest are some of the approaches based on the third category, as technological advances have made it possible to obtain materials suitable for permanent sealing at high temperatures and pressures.
