摘　　要：质量、质心和转动惯量是再入类飞行器的重要参数,其测量精度对飞行器控制至关重要。详细介绍并对比分析了X-38飞行器质量特性测量方法,测量结果表明:采用三点法c质量和三个方向质心位置,采用单点悬挂法和弹簧工作台可以准确测量三个方向的转动惯量。X-38飞行器的质量特性测量方法对于类似的再入飞行器质量特性测量具有很好的参考意义。The important parameters of aerospace vehicle include mass, centroid and moment of inertia, etc. The measurement precision of these parameters is vital for the vehicle control. This paper detailedly described the mass, centroid and moment of inertia measurement of X-38 vehicle, and analyzed these different measurement methods. The measurement results show that applying three-point method can accurately measure the mass and center of gravity, and single-point suspension and spring table can accurately measure three inertia of the vehicle. Finally, these methods that were applied for the X-38 vehicle have a very good significance to the mass properties measurement of other similar aerospace vehicles.
