根据短距起飞垂直降落(STOVL)飞行器的特点,研究了STOVL飞行器在飞行品质方面的特殊要求。在总结AGARD 577和MIL-F-83300飞行品质规范的基础上,分析了STOVL飞行器在过渡和悬停状态下对俯仰、滚转、偏航的控制效能要求,以及阻尼比和频率要求。计算了某STOVL无人飞行器在过渡状态下的部分性能和飞行品质,分析了其纵横向稳定性,并根据飞行品质要求提出了一些建议。
According to the characteristics of STOVL aircraft, the special requirements of STOVL aircraft in flight quality are studied. Based on the flight quality specifications of AGARD 577 and MIL-F-83300, the control performance requirements of pitch, roll and yaw for STOVL aircraft during transition and hovering are analyzed, as well as the damping ratio and frequency requirements. A part of the performance and flight quality of a STOVL UAV under transient conditions were calculated. The longitudinal and transverse stability of the STOVL UAV was analyzed, and some suggestions were put forward according to the flight quality requirements.
