低动压着舰状态下飞机的操纵特性研究

Research of Handling Characteristics of Aircraft in Low Dynamic Pressure Situation

低动压着舰状态下飞机的操纵特性下降,导致轨迹角不能跟踪姿态角的变化,从而对着舰安全造成严重影响。首先通过剖析历史上已有的观点,提出研究低动压状态飞机轨迹角响应问题时应全面考虑速度稳定性、轨迹稳定性和机动性。其次对两种动力补偿系统进行了分析,其中速度恒定动力补偿实际上对应速度稳定性和轨迹稳定性,而迎角恒定动力补偿兼具速度稳定性、轨迹稳定性和机动性增强。最后的仿真证实,考虑速度稳定性、轨迹稳定性和机动性的迎角恒定动力补偿是全面的、可行的。

The handling characteristics degradation of aircraft in the low dynamic pressure situation can cause that the flight path angle cannot track the attitude angle, and then the safety of carrier landing is influenced. After enumerating and analyzing some historic explanations, a new and all-sided view concludes： when considering flight path angle response of aircraft in the low dynamic pressure situation, speed stability, flight path stability and maneuverability show all be concerned. And this analysis suggests that the automatic power compensator system （APCS） with constant airspeed actually corresponds with speed stability and flight path stability, and APCS with constant angle of attack is related to all the three factors. Numerical simulation also indicates the view is proper and feasible.
