| 摘 要： | 根据倾转旋翼飞行器的构型特点,建立了倾转旋翼飞行器旋翼、机翼、短舱、机身、平尾(含升降舵)和垂尾(含方向舵)的气动力模型,研究了倾转旋翼飞行器的操纵策略以满足直升机模式的悬停/小速度飞行、直升机模式向固定翼飞机模式转换的过渡飞行和固定翼飞机模式的高速飞行,并运用最优方法研究倾转旋翼飞行器在不同飞行速度下作稳定对称飞行时的配平方法.最后以XV-15倾转旋翼飞行器为例,进行各种飞行模式的配平.结果表明:本文所述方法能合理地给出倾转旋翼飞行器在整个稳定飞行速度范围内的操纵量和姿态.

| Abstract: | A control strategy and its corresponding trimming algorithm are studied for the tilt-rotor aircraft under various symmetrical steady level flight conditions.The conditions cover the hover and low speed flight in helicopter mode,the transitional flight from helicopter to airplane and the high speed flight in fixed-wing airplane mode.General aerodynamic forces and moments of tilt-rotor,wing,fuselage,nacelle,elevator,horizontal,and vertical stabilizers are modeled.Together with the control strategy,an optimiza... |
