捕获轨迹法在××无人机投放试验中的应用

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。

THE APPLICATION OF A CAPTURE OBJECT TRAJECTORY'S METHOD IN THE PILOTLESS AIRCRAFT DROPPING TEST

A capture object trajectory's technique is introduced in this paper.It is a fusion of measuring forces and flight trajectory analysis wind tunnel testing technique. This method had been used for predicting pilotless aircraft's separated characteristics. This method can measure the object trajectory and its aerodynamic forces in the complex flow field accurately and predicted the compalibility bctween the pilotless aircraft and the parent airplane. The flight testing results proofed that the tectinique is a method of the accurate predicting object separated characteristics, and solved the safe separated main problem of the high aspect ratio pilotless aircraft.
