摘　　要：在单脉冲冲量测量方法的基础上,增加激光脉冲提取和摆杆控制单元,提出了一种基于复摆模型的多脉冲冲量耦合系数测量方法。分析了多脉冲的两种测量模式及实现流程,解决了数据处理面临的新问题,并对该方法进行了检验,结果表明:所设计的激光脉冲提取和摆杆控制单元满足25Hz频率要求,可实现在40ms内提取多脉冲序列的任意一个脉冲;模拟多脉冲序列下测得两种模式15°锥形喷管的冲量耦合系数为371.0～375.3N/MW,具有很好的一致性。该方法可用于吸气式激光推进的多脉冲性能研究,并作为其他多脉冲研究方法的有效补充。A measuring method of multiple-pulse impulse coupling coefficient based on compound pendulum model was presented,in which a laser pulse extracting and a pendulum controlling unit was added to the single-pulse impulse measurement system.Two multiple-pulse measurement patterns and their implementation procedure were analyzed.Then new problems of data processing for the maximal angle were solved.Finally,the multiple-pulse measuring method was tested.Results indicate that the design of the laser pulse extractor...
