摘要
研究用扭摆法测量飞行器转动惯量,并对该方法的测量误差进行分析。分析了飞行器IXX与IYY(IZZ)的比值以及测试倾斜角对IYY(IZZ)测量精度的影响,得出当试件的IYY(IZZ)/IXX大于5后,转动惯量的测试误差基本稳定的结论。
A method of testing the aerocraft＇ s moment of inertia is introduced which could avoid destroying it＇s structure in addition to indicates that error for testing moment of inertia is related with the ratio between IYY（IZZ） and IXX and sloping angle. Measurement error for an example is analyzed. The example indicates that measurement error for the aerocraft＇ s moment of inertia is next to changeless when the ratio between Irr（Izz） and Ixx is greater than 5.
