The invention relates to an unmanned aerial vehicle ground launching test system and method. The test system comprises an aircraft model, an attitude measurement sensor, an electromagnet, a balancing weight, a mounting disc, a tower crane and an elastic protection rope. The aircraft model is adsorbed on the mounting disc through an electromagnet, and lifting of the test model is completed through a lifting hook of the tower crane; the tower crane platform is used for remotely controlling the power-on and power-off conditions of the electromagnet, remote autonomous launching of the aircraft model is achieved, and a low-altitude launching test of the aircraft model is carried out. The center-of-gravity position of the model is adjusted by replacing a balancing weight at the tail of the aircraft model so as to change the longitudinal static stability margin, and the longitudinal pitching trim is changed by adjusting the rudder surface deflection angle of an empennage. And reading data of the attitude measurement sensor to obtain the influence of the longitudinal static stability margin and the longitudinal pitching trim on the dive-to-level flight dynamic characteristics after the aircraft model is put at low altitude, and providing a design basis for the dive-to-level control law of the aircraft model.

    本发明涉及一种无人机地面投放试验系统及方法,试验系统包括飞行器模型、姿态测量传感器、电磁铁、配重块、安装盘、吊塔、弹性保护绳。飞行器模型通过电磁铁吸附在安装盘上,并由吊塔的吊钩完成试验模型的升降;利用吊塔平台,通过对电磁铁的通电、断电情况进行遥控,实现飞行器模型远程自主投放,开展飞行器模型的低空投放试验;通过更换飞行器模型尾部的配重块调整模型重心位置进而改变纵向静稳定裕度,通过调整尾翼舵面偏角进而改变纵向俯仰配平。读取姿态测量传感器数据,得到纵向静稳定裕度和纵向俯仰配平对飞行器模型低空投放后俯冲改平飞行动力学特性的影响,为飞行器模型俯冲改平控制律提供设计依据。
