介绍一种投放外挂物脱离母机状态的风洞测力试验和飞行轨迹分析融于一体的“捕获轨迹”方法。该方法能较精确地获得外挂物在复杂干扰流场中所受的空气动力和力矩，实时地提供离机后的轨迹和姿态，预测了无人机和母机之间飞行是否相容的问题。全尺寸的飞机投放试验表明，“捕获轨迹”技术是一种精确预测外挂物分离特性的方法，解决了大展弦比无人机安全离机的关键问题。
This paper introduces a method of “Tracing Trajectory” which integrates wind load test and flight path analysis, which put out the plug-in from the base station. The method can obtain the aerodynamic force and torque of the plugged object more accurately in the complicated interference flow field, and provide the trajectory and attitude of the aircraft in real time and predict the compatibility of the UAV and the aircraft. The full-scale aircraft launch test shows that the “capture trajectory” technique is a precise method of predicting the separation characteristics of plug-ins, and solves the key issue of safe escape of large aspect ratio UAVs.
