Fixed Wing Angle Measurement of Two-dimensional Trajectory Correction Fuze

针对固定翼二维弹道修正引信转角控制在炮射环境中翼面角度测量难度大、成本高的问题,提出了固定翼二维弹道修正引信转角控制翼面角度地面测量方法。该方法利用坐标系转换关系计算出地磁矢量在准弹体坐标系弹轴径向平面分量与准弹体坐标轴之间的夹角,结合目标角的分析,计算出外弹道起控后地磁分量和翼面的夹角及其变化规律;然后通过测量双旋转台径向平面上地磁分量的方向、飞行控制模块装定炮位射击参数,存储并读取外弹道航偏角和俯仰角数据,最终在双旋转台实现二维弹道修正引信翼面转角控制角度的测量。仿真和实验结果表明,该方法能够方便、准确地实现固定翼二维弹道修正引信的转角控制在炮射环境中翼面角度的测量。

Aiming at the problem of the difficulty and costly measurement for fixed wing two-dimensional trajectory correction fuze angle control under shooting conditions,a method for angle ground measurement of fixed wing two-dimensional trajectory correction fuze angle control was proposed.The party used the coordinate system conversion relationship to calculate the angle between the radial plane component of geomagnetic vector in the quasi-projectile coordinate system and the quasi-projectile axis,combined the analysis of the target angle to calculate the angle between the geomagnetic component,the wing and its changing law after the external ballistic control.Next,by measuring the direction of the geomagnetic component on the radial plane of the dual rotating table,the flight control module set the shooting parameters of the gun position,stored and read the data of the outer ballistic yaw angle and pitch angle,and finally the wing angle measurement of two-dimensional trajectory correction fuze angle control was realized on the double rotating table.Simulation and experimental results showed that the method could conveniently and accurately realize the angle measurement.
