本文阐述了航天飞机固体火箭助推器推力向量控制伺服作动器的设计。文中除设计原则和工作原理外,还概述了研制和鉴定试验方案中的重要内容。另外,还介绍了在执行试验方案过程中发生的异常现象以及采取的对策。 In this paper, the design of the thrust vector control servo actuator for the space shuttle’s solid rocket booster is described. In addition to the design principles and principles of work, the paper also outlines the important contents of developing and identifying experimental schemes. In addition, the anomalies that occurred during the implementation of the test protocol and the countermeasures taken were introduced.
