The invention provides an unmanned aerial vehicle gravity center and thrust line distance measuring device and method. On the basis of single-point hoisting on the back of an unmanned aerial vehicle,a lifting point is arranged at the intersection of the thrust line and aircraft back of the unmanned aerial vehicle; a measuring cylinder device or a sensor device is installed on a belly thrust cone;the unmanned aerial vehicle does not need to be turned over, the distance between the actual gravity center of the unmanned aerial vehicle and the thrust line is directly read on the measuring cylinder device after single-point hoisting is conducted on the back, or a measured deflection angle is converted into the distance between the actual gravity center and the thrust line through the sensor device. When an unmanned aerial vehicle abdomen vertical hanging method is used to measure the distance between the gravity center and the thrust line of the unmanned aerial vehicle, the unmanned aerial vehicle with the large vehicle body size and weight is difficult to turn over, and as a result, measurement result accuracy is affected due to inconsistency of oil center positions under an invertedhanging state and a launching state, and back reading is inconvenient. With the device and method of the invention adopted, the above problems can be solved.

    本发明提供了一种无人机重心与推力线距离测量装置及方法,通过无人机背部单点起吊,在推力线与机背相交处设置吊点,机腹推力锥上安装测量筒装置或传感器装置,无需翻转无人机,通过背部单点起吊后,直接在测量筒装置上读取无人机实际重心与推力线之间距离,或者通过传感器装置将测量的偏角换算成实际重心与推力线之间的距离。本发明通过上述方法和装置解决了无人机腹部竖直吊挂法测量无人机重心与推力线之间距离时,机体尺寸、重量较大的无人机翻转困难,且倒挂状态与发射状态油心位置不一致影响测量结果准确性,背部读数不方便等问题。
