过失速机动飞行模拟与操纵效能分析

在大迎角非线性气动力模型和推力矢量发动机模型的基础上,结合非线性控制方法和与常规飞行增稳控制模态转换方法,实现飞机常规飞行包线内和过失速区域的全范围飞行模拟,同时提出了过失速机动操纵效能分析方法。通过对推力矢量飞机操纵效能的全面分析,验证了推力矢量控制有效实现和显著提高过失速区的机动能力。飞机全状态范围的过失速机动飞行模拟与操纵效能分析将为现代高机动飞机过失速机动飞行试验提供重要的技术支持和理论依据。

Flight simulation and control effectiveness analysis for aircraft post-stall maneuvers

Based on a high angle of attack and nonlinear aerodynamic model and a thrust-vector engine model,combined a nonlinear dynamics inversion control method with a conventional flight stability augmentation mode-converter method,the flight simulation is established in all ranges of normal flight and post-stall areas.At the same time,the analysis method of aircraft's post-stall maneuverable control effectiveness is presented.It is proved that the control of thrust-vector can noticeably improve the capacity of air...
