Abstract：Based on three-point weighing method and torsion pendulum method,a mass property measurement system which is adapted to the Unmanned Aerial Vehicle with quality of 200～1 000 kg,the total length less than 4 m,and the wingspan of no more than 2 m is designed. This system is able to measure all the quality characteristic parameters by one time, is easy to make and use. Compared with the traditional vertical installation method, small flip angle measurement is presented, which can not only improve the measurement accuracy, but also ensure the safety of the product measurement. The actual sample measurement results show that measurement time reduced by 60%, the relative errors of the measured mass centroid are all less than 1%, the relative errors of the measured moment of inertia and product of inertia are all less than 4%.
