The invention provides an unmanned aerial vehicle gravity center measuring and thrust line matching device and method; the angle of the unmanned aerial vehicle is adjusted through the device, calculation of the gravity center in the Z direction is achieved according to angle changes, and compared with a traditional calculation method, unmanned aerial vehicle position changes are small, operation is easy, and under change errors, measurement of the actual gravity center of the unmanned aerial vehicle is more accurate; and the device and method can be applied to actual gravity center measurementand thrust line matching of a large-size and high-weight unmanned aerial vehicle. By means of the device and method, the defects that in the prior art, under the condition that the unmanned aerial vehicle is launched through rocket boosting, the actual gravity center of the unmanned aerial vehicle is measured inaccurately, the gravity center of the unmanned aerial vehicle in the Z direction is difficult to measure accurately, and an unmanned aerial vehicle gravity center measuring method is not suitable for large-size and high-weight unmanned aerial vehicles are overcome, and meanwhile cost is saved.

    本发明提出了一种无人机重心测量及匹配推力线的装置及其方法,通过装置调整无人机的角度,根据角度变化实现Z方向重心的计算,相比于传统的计算方法,无人机位置变化小,操作简易且变化误差下,无人机的实际重心的测量更加精准,且可适用于大体积高重量的无人机实际重心测量及推力线的匹配中。本发明通过装置及方法,解决了现有技术中在火箭助推发射无人机的情况下,无人机的实际重心测量不准确,难以精确测量无人机Z方向的重心,且无人机重心测量方法对大体积高重量的无人机不适用等缺陷,同时还节约了成本。
