目的 观察盘旋飞行时由飞机姿态突然改变所诱发的超G错觉,为我军飞行员进行该错觉的训练提供依据。 方法 根据超G错觉理论和地面试验结果设计飞机以一定坡度盘旋过程中突然改变倾斜角度的飞行方案,在歼教7 飞机上,由1 名飞行教员在前舱按此方案带飞11 名受试飞行员,受试飞行员在后舱闭眼体会飞机姿态,在规定的时间点报告感觉到的飞机姿态,对此知觉与飞行参数记录系统记录的飞机实际姿态进行同步比较,判断飞行员是否出现错觉及错觉程度。每名受试飞行员体验1次。 结果 记录有效架次9架次(9人次),8人次出现对飞机坡度改变夸大的错觉,飞机以60°坡度飞行时实际改变坡度9 8°±0 7°,飞行员感觉到的坡度变化平均为20 4°±8 5°。 结论 超重飞行中,飞行员会对飞机姿态的改变产生夸大的错觉,飞行员可通过体验这种错觉以预防由此引发的事故。本飞行方案可以供该错觉的空中模拟体验训练之用。
Aim To observe the super-G illusion induced by the abrupt change of attitude of a helicopter in a hover flight, and provide the basis for our pilots to carry out the illusion training. Methods According to the theory of super G and the ground test results, the flight plan was designed to suddenly change the tilt angle during the helicopter hovering on a certain gradient. On the J-7 plane, a flight instructor took the program in the front cabin to fly 11 participants Pilots and pilot pilots perceive the attitude of the aircraft in the rear compartment with their eyes closed and report the sensed attitude of the aircraft at specified time points. This perception is compared with the actual attitude of the aircraft recorded by the flight parameter recording system to determine whether the pilot is illusion or illusion degree. 1 pilot experience per pilot. The results recorded 9 sorties (9 person-times) of effective sorties and 8 mistakes that exaggerated the change of aircraft grade. The aircraft actually changed the grade of 9 8 ° ± 0 7 ° when flying at 60 °, and the average change of pilot grade was 20 4 ° ± 85 °. Conclusion In overweight flights, pilots can have an exaggerated illusion of changing their attitude, and pilots can experience this illusion to prevent the resulting accident. This flight plan can be used for this illusion of aerial simulation experience training purposes.
