为了进一步提高倾转旋翼飞行器的建模精度,考虑旋翼挥舞运动、采用有限状态尾迹模型描述旋翼诱导速度,进而建立旋翼气动力数学模型;考虑旋翼/机翼/干扰,建立相应气动力数学模型;针对倾转旋翼飞行器操纵冗余问题,建立了适用于全模态的操纵策略数学模型。最后以通用倾转旋翼飞行器数学模型和飞行试验数据,对建立的数学模型进行验证。仿真结果表明建立的飞行动力学模型具有良好的精度,适用于飞行动力学其他问题的分析研究。
In order to further improve the modeling accuracy of tiltrotorcraft, the rotor wielding motion is considered and the rotor induced velocity is described by the finite state wake model, then the rotor aerodynamic mathematical model is established. The corresponding aerodynamic mathematical model is established considering the rotor / wing / disturbance. Aiming at the maneuvering redundancy problem of tiltrotor aircraft, a mathematic model of maneuver strategy for full mode is established. Finally, the mathematic model and the flight test data of the universal tiltrotor rotorcraft are used to verify the established mathematical model. The simulation results show that the established flight dynamics model has good accuracy and is suitable for the analysis of other problems of flight dynamics.
