旋转弹转速测量系统设计

Aiming at the problem that the traditional micro-electro-mechanical system gyroscope can not meet the test requirement of the range and accuracy at the same time, a new speed measurement method is proposed by adding a platform to isolate the high-speed rotation of the missile. The system measurement principle and construction are introduced, and the hardware and software design of the system is completed. The effectiveness of system is validated by high precision flight simulation turntable experiment. The measurement system can accurately measure the rotating speed of the missile, the error is about 1°/s, which realizes the purpose of measuring the high rotational speed by the high precision and small range gyroscope.
