摘要
建立了完整的直升机飞行动力学数值仿真模型。建模时综合考虑了直升机的主要气动力部件的建模以及气动干扰等问题,详细讨论了与主旋翼相关的翼型气动力模型、诱导速度模型和挥舞运动模型的建模方法。基于层次化、模块化的建模原则,整个仿真模型最终在Simulink平台上得到了实现。最后采用算例直升机数据,根据提出的建模方法进行了定直飞行的配平计算和操纵响应分析,仿真结果证明了建模理论和方法的合理性和有效性。
A mathematical model for helicopter flight dynamics simulation was developed. In the process of modeling, the construction of the primary aerodynamic components of helicopter and the aerodynamic interference effects were considered comprehensively. Main rotor is the key part of helicopter modeling, and the associated modeling methods of aerofoil aerodynamic loads, rotor inflow dynamics and blade flap motion were discussed in detail. Based on the principle of hierarchy and modularity, the whole model was established in Simulink. Finally, the trim calculation and response analysis were carried out with the example helicopter＇s data. The simulation results validate the rationality and validity of modeling theories and methods.
