为实现二维修正弹的高速稳定控制,依据弹道修正原理对某二维修正弹在不同飞行速度下舵翼受到的减旋力矩进行模拟实验研究。装置中采用阻尼电机搅拌油液使油盒受到减旋力矩来模拟修正弹舵翼受到的减旋力矩。对减旋力矩进行FLUENT仿真计算,并且对仿真结果用测力装置进行实际测量,电机和油盒的转速由霍尔测速装置进行测量,实验数据用MATLAB进行分析。实验结果表明,该实验装置能够满足修正弹控制机构研究的要求。

In order to achieve high-speed stability control of two-dimensional correction projectile, the spin-decelerating moment of a two-dimensional correct projectile with rubber and fin under different speed was studied by simulation experiment based on the principle of trajectory correction. The equipment motor damping to stir oil which oil box under spin-decelerating moment simulate spin-decelerating moment of the correction projectile. The spin torque calculated by FLUENT simulation software, the oil box simulation result was measured by strain gauge dynamometer, the of the motor and oil box were measured by hall speed sensor, and the test data was analyzed by MATLAB. The experiment result indicates that the designed equipment could meet the test requirement of correction projectile control.
