火箭弹滚转角测量方法研究

为了对火箭弹实施某种控制以达到减小火箭弹射弹散布和增加射程的目的,需要实时测量火箭弹滚转角度.本文比较了二加速度计法、四加速度计法和感应线圈法等三种火箭弹滚转角测量方法,并详细地分析了该方法的测试原理误差.这些方法的共同特点是数据处理过程简单,适合实时测试的要求,测试系统结构简单,容易实现低的成本和高的工作可靠性.

Study on the Measurement of Rocket Rotation Angle

To lower the shell distribution and to extend the range of rocket,a nozzle-like rocket-bounded actuator is deliberately designed to alter the outer trajectory.Real-time measurement of rocket rotation angle is needed to help the actuator act at the precise time.Three test methods,including two-accelerometers method,four-accelerometers method and geomagnetic induction coil method,for measuring rocket rotation angle are put forward in this paper.With its comparatively simple combination,the method tends to meet the requirement of real-time measurement,high reliability,low cost,and high feasibility.
