摘要

摘要: 针对倾转旋翼飞行器悬停和小速度前飞的直升机飞行模式下旋翼下洗流对机翼的气动干扰影响,建立了一个机翼向下载荷的计算模型.该模型中,最关键的是建立旋翼对机翼的气动干扰面积模型.此模型考虑了倾转旋翼飞行器几何尺寸条件、发动机短舱倾转角和飞行状态等参数.最后将此模型集成到XV-15倾转旋翼飞行器飞行动力学模型中,进行配平计算,配平结果表明该倾转旋翼飞行器旋翼对机翼气动干扰产生的向下载荷模型是合理和有效的,适用于倾转旋翼飞行器的飞行动力学研究.

Abstract: A mathematical model for calculating wing download of tiltrotor aircraft in helicopter mode,which covers hover and low-speed forward flight,was given according to the aerodynamic interaction effect of the rotor downwash flow on the wing.The rotor and wing interaction area model considered the tiltrotor aircraft geometry scale,the tilt angle of the nacelle and the flight condition as key elements.Then the model was integrated into the XV-15 tiltrotor aircraft flight dynamic model.The trim results show that the rotor and the wing interaction download model of tiltrotor aircraft is reasonable and effective.The wing download math model is suitable for tiltrotor aircraft flight dynamic mathematical model.
