摘要
激光推进冲量耦合系数是激光推进的重要参数,反映激光能量转化为动能的能力。提出了水平双线支撑激光推进试验方法,推导了水平双线支撑激光推进时光船的运动方程和测量方程;通过高速相机测量位移,利用卡尔曼滤波计算速度的方法;解决了激光脉冲瞬间作用时速度随机起伏大和计算困难的问题。为水平激光推进冲量耦合系数的计算,提供了工程测量和计算方法。
Impulse coupling-coefficient is an important index, which represents the capability of laser energy transforming kinetic energy. Based on the measure displacement method of high-speed photograph technology, using Kalman filtering method, velocity calculated method of lightcraft is proposed for horizontal parallel wire supported laser propulsion. From the proposed testing and calculation method, the problem of velocity random fluctuating phenomenon owing to test data fluctuating is resolved. The presented method can be used in engineering measure and design for calculating impulse coupling-coefficient of laser propulsion.
