弹旋频率是影响旋转导弹制导精度的主要因素之一。本文提出了一种弹旋频率测量用大量程MEMS陀螺仪技术方案,开展了大量程MEMS陀螺仪在旋转导弹上的应用研究,解决了大量程MEMS陀螺仪在偏心安装、较大力学环境下提高测量精度等问题,通过了飞行试验验证,实现了旋转导弹弹旋频率的精确测量。 Spinning frequency is one of the main factors affecting the guidance accuracy of rotating missile. In this paper, we propose a large-scale MEMS gyroscope technique for measuring the frequency of projectile rotation. The application of MEMS gyroscopes on a large number of rotors is carried out, which solves the problem that the MEMS gyroscopes with large- Measurement accuracy and other issues, passed the flight test to verify, to achieve a precise measurement of rotating missile rotary frequency.
