摘要
为了研究特殊气象状况下737客机起落架起飞性能,以雾、微雨、中雨、冰雪四种相对简化的气象条件为例,建立了以上气象条件下跑道与客机的摩擦系数模型用于仿真测试。由于飞机地面滑跑时,起落架将产生一定的缓冲导致飞机滑跑过程中姿态角的改变,因此设计了飞机起落架系统的受力模型的计算方法,并将建立的起落架系统模型应用到JSBSim飞行动力学系统中。仿真验证表明,摩擦系数模型和计算模型建模合理,摩擦系数计算数据比较吻合实际情况。
In order to study the takeoff performance of Boeing 737 airliners in special meteorological conditions, a frictional coefficient model of runway and airliner was established for simulation test under the meteorological conditions of fog,light rain, moderate rain and snow. Because of the change of the attitude angle caused by the landing of the landing gear, the design method for the force model of the aircraft landing gear system was designed, and the established landing gear system model was applied to the JSBSim flight dynamics system. The simulation results show that the friction coefficient model and the calculation model are reasonable, and the friction coefficient calculation data are in good agreement with the actual situation.
