摘要
为得到飞机的尾旋特性准确的非线性仿真结果，提出了新的综合数据分析方法，在气动力建模时采用综合因子，合理地将总角速度分解成沿速度矢的分量和沿３ 个体轴的分量，沿速度矢量的旋转角速度用于旋转天平试验数据；旋转角速度的其它分量用于振荡天平试验数据，综合地使用了各类试验数据。给出的不同类型的六自由度仿真结果表明，综合数据分析法的结果和试飞结果相当吻合。
A new integrative data analysis technique is presented and is used in an accurate nonlinear simulation to analysis spin characteristics of an airplane. By integrative factor methodology in aerodynamic coefficient building, it is reasonable to resolve the total rotation vector into a component along the velocity vector and components about three body axes. The component of rotation along the velocity vector is used with the rotary balance test data and other components of the rotation vector are used with the forced oscillation test data. The varied test data is used integrately. The 6 DOF simulation results in the paper show that the results of integrative data analysis technique are consistent with those of the flying tests considerably.
