| 摘 要： | 为了研究燃气舵气动特性的形成机理,采用N-S方程模拟了推力矢量燃气舵表面压力分布,得到了不同舵偏角下燃气舵周围压力的变化曲线,分析了燃气舵表面不同位置压力的大小.结果表明,舵偏角的变化对燃气舵背风面的压力影响不大;随着舵偏角的增大,燃气舵迎风面的压力变化很大;在升力贡献方面,靠近根部区域大于梢部,最大厚度处上游区域大于下游.

| Abstract: | To study the forming mechanism of aerodynamic characteristics of jet vane,N-S equations were used to simulate the pressure distribution on the surface of thrust vector control(TVC) jet vane.The curves of the jet vane pressure surrounding the jet vane were obtained under different rotation angle of the jet vane.The pressure of different place on the jet vane surface was analyzed.The results indicate that the change of rotation angle of the jet vane have little influence on the pressure on the lee surface of ... |
