| 摘 要： | 在考虑跑道不平度和摩擦力对飞机滑跑姿态以及气动力的影响下,建立了跑道、飞机本体和起落架的动力学模型,并对飞机在简易跑道上的起飞性能进行了仿真研究。通过对飞机起飞的运动轨迹和姿态的数值模拟,得到了飞机起飞性能参数,以及跑道不平度对起落架及机体的随机振动影响。仿真结果表明,所建立的动力学模型和相应的仿真方法能够满足飞机在不同跑道特性起飞性能研究的需要。

| Abstract: | By analyzing the fluctuation and the friction of the runway impact on the ground running attitude and the aerodynamics,the dynamic model of the airplane is established,and then,the research of the take-off performance of the transport on the air strip is studied in this paper. According to the simulation of the motion trajectory and the attitude of the flight,the parameters of the take-off performance and the influence of fluctuation of the runway on the random oscillation of the landing-gear and fuselage a... |
