The invention provides an anti-hooking protective cover and locking device of a control moment gyroscope in the technical field of spacecrafts. The anti-hooking protective cover comprises a control moment gyroscope body, a common interface locking gasket and a coaxial thin-wall protective cover. The coaxial thin-wall protective cover is arranged on the control moment gyroscope body, and the plurality of common-interface locking gaskets are respectively arranged in the peripheral direction of the control moment gyroscope body. The aim of preventing the control moment gyroscope on a spacecraft from being hooked is achieved through simple mechanical design, additional interfaces are not needed, the existing design of the moment gyroscope is not changed, and the staggered frequency design can be achieved by adjusting the thickness of the coaxial thin-wall carbon fiber protective cover according to resonance and resonance phenomena of the control moment gyroscope, so that the anti-hooking effect of the control moment gyroscope on the spacecraft is achieved. And the device has the characteristics of simple structure, light weight and high reliability.
本发明提供了航天器技术领域一种控制力矩陀螺的防钩挂防护罩及锁紧装置,包括控制力矩陀螺本体、共接口锁紧垫片以及同轴薄壁防护罩。同轴薄壁防护罩设置在控制力矩陀螺本体上,多个共接口锁紧垫片分别设置在控制力矩陀螺本体四周方向上。本发明通过简单的机械设计即达到了航天器上的控制力矩陀螺防钩挂的目的,且不需要额外的接口,不改变力矩陀螺现有设计,针对控制力矩陀螺的共振与谐振现象,还可通过调整同轴薄壁碳纤维防护罩的厚度来达到错频设计,且本发明具有结构简单,重量轻,可靠性高的特点。
