速率陀螺在运载火箭上的应用及冗余方式

Application of Rate Gyroscope on Launch Vehicle and Its Redundancy Method

针对速率陀螺在运载火箭上的应用以及冗余方式进行了介绍,从速率陀螺的应用原理、冗余方式两方面进行了总结与归纳。针对CZ-2F双冗余速率陀螺方案,给出了姿控网络设计频域曲线及时域仿真结果,仿真结果表明,考虑单个速率陀螺故障下进行姿控系统设计,保证具有足够的稳定裕度,可以实现火箭在故障下的稳定飞行。

The application of rate gyroscope on the launch vehicle and the redundancy method are introduced,and the application principle and redundancy method of rate gyro are summarized.For the LM-2F dual-redundant rate gyroscope scheme,the frequency-domain curve and time-domain simulation results of the attitude control network design are given.The simulation results show that the attitude control system is designed considering the failure of a single rate gyroscope to ensure sufficient stability margin,The stable flight of the rocket under failure can be realized.
