针对旋转体姿态控制的技术要求,提出了一种新型微机械摆。微机械摆安装在旋转体上,利用旋转体自旋代替传统陀螺由自身结构产生的驱动力,使微机械摆具有陀螺效应,能同时输出偏航、俯仰和自旋角速度,具有3个传统陀螺的功能。飞行试验结果表明,微机械摆用于旋转体控制舱,15 s输出信号测量精度为0.5°。
A new type of micro-machined pendulum is developed for the technical requirements of rotary carrier attitude control.Mounting on rotary carrier,the micro-machined pendulum uses the spinning of rotary carrier instead of traditional gyroscope's driving force that produced by its driving structure to get gyroscopic effect.It can output pitching,yawing and rolling angular rates simultaneously,which is equivalent to three traditional gyroscopes.Flight experiments show that the micro-mechanical pendulum has a quite good effect in attitude control system for rotating carrier and rockets,and the output accuracy in 15 seconds measurement is 0.5°.
