针对一种自转旋翼/机翼组合构型飞行器的飞行动力学特性进行了研究,通过和样例自转旋翼机的对比,分析了它的配平特性、稳定性及操纵响应方面的一些特点。研究表明通过自转旋翼和机翼的组合运用,本文研究的高速型旋翼机飞行速度显著提高,高速前飞时自转旋翼逐步卸载,其转速逐步下降到了低速前飞时的40%;该高速型旋翼机的浮沉模态在低速阶段不稳定,但周期和倍幅时间比较长,随着前飞速度的增加,各模态均趋于稳定;该高速型旋翼机的纵横向周期变距操纵响应略小于样例自转旋翼机,可以考虑增加襟副翼来改善。
Aiming at the flight dynamics of an autorotating rotor / wing combination aircraft, the characteristics of its balance, stability and handling response are analyzed by comparing with the prototype autorotator. The research shows that the flying speed of the high-speed rotor is remarkably improved by the combination of rotor and wing, and the rotor is gradually unloaded at high-speed forward flight and its speed gradually drops to 40% at low-speed forward flight. The high-speed rotor The mode of floating and sinking of aircraft is unstable at low speed, but the period and multiplication time is relatively long. As the speed of forward flight increases, the modal stability tends to be stable. The longitudinal and transverse periodic pitch response of the high-speed rotorcraft is slightly Less than the sample autorotator, consider adding flaperons to improve.
