摘要

摘要: 总结和分析了旋翼、机翼、机身、短舱和尾翼气动力模型和操纵机构特点,其中旋翼气动力模型以准定常叶素理论为基础,机翼和尾翼气动力模型以升力线理论为基础,并分析了旋翼尾流对机翼气动力气动干扰问题;建立了全量非线性倾转旋翼机飞行力学模型;以XV-15为样机,对倾转旋翼机在不同飞行模式和飞行速度下飞行力学特性展开了详细研究,得到的结论有助于深入了解倾转旋翼机飞行力学特性,也可用于倾转旋翼机飞行控制系统设计.

Abstract: A flight dynamics model of the tilt rotor aircraft was established based on the research into the aerodynamic of the rotors,wing,fuselage,nacelle,empennage and control system.Quasi-steady element theory was used to analyze the lift,drag,moment and the flapping motion of the rotors.The lift line theory was used to research the aerodynamics of others,and then an investigation was conducted on the XV-15 tilt rotor aircraft.The results can be helpful to realize the characteristics of tilt rotor aircraft,also be useful to flight control design.
