目的 了解某型高性能战斗机在空战训练课目中推拉效应动作发生的频率和强度。方法 回顾分析某型单座高性能战斗机单机战斗特技和双机空战截击课目飞行参数记录中的加速度数据,统计导致推拉效应的飞行动作的频数及该动作G负荷的变化幅度。结果 这两个飞行课目中,34.1％的起落有推拉效应动作。单机战斗特技比双机空战截击出现推拉效应动作的频率高,G值变化幅度也大。结论 某型高性能战斗机空战训练飞行中存在可以导致推拉效应的飞行动作,这是一种危险因素,应予以预防。
Objective To understand the frequency and intensity of the push-pull effect of a high-performance fighter jet in the air-combat training course. Methods The acceleration data of a single-seat high-performance fighter’s single-combat and two-aircraft air combat intercept were analyzed retrospectively. The frequency of the flight resulting in the push-pull effect and the magnitude of the change in the G load were also analyzed. As a result, 34.1% of the ups and downs in both flight courses were motivated by the push-pull effect. Stand-alone combat stunt than the two air combat interception push and pull effect of the frequency of action is high, G value changes are also large. Conclusion There is a flight action that can lead to the push-pull effect in the air combat training flight of a high-performance fighter. This is a risk factor and should be prevented.
