Abstract

For testing rolling angular rate and axial acceleration of rocket projectile, sensors with high anti-impact capability are needed. MEMS-based inertial sensor is adaptive to the high shock circumstance. This work introduces a measuring system based on MEMS gyros and MEMS accelerometer. By set MEMS inertial sensor in air delivery land mine of rocket, use polyurethane plotting the sensor and circuit wafer, it can test the rolling angular rate and axial acceleration of the mine, and storage the data in the flash memory safely. In the rocket experiment the system had been collected the inertial information of the air delivery land mine. The results show that the MESMS-based system is available in the measurement of rocket and can be used repeatedly.
