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。
In order to obtain accurate non-linear simulation results of the tail rotation characteristics of the aircraft, a new integrated data analysis method is proposed. In the aerodynamic modeling, a comprehensive factor is used to reasonably decompose the total angular velocity into components along the velocity vector and along the three body axes The rotational angular velocity along the speed vector is used to rotate the test data of the balance. The other components of the rotational angular velocity are used to oscillate the test data of the balance, and various types of test data are used synthetically. Different types of six-degree-of-freedom simulation results show that the results of the integrated data analysis are in good agreement with the results of flight test.
