关于某型飞机正飞螺旋特性的研究已经比较充分,但对其反螺旋的认识还十分缺乏。以该型飞机一起反螺旋飞行事故中记录的主要飞行参数为依据,通过计算反螺旋动态参数,分析了该型飞机的反螺旋特性。研究结果表明,该型飞机的反螺旋属于稳定的陡直振荡反螺旋。所提出的螺旋特性的推算方法为利用飞行参数研究和分析反螺旋特性提供了理论依据,对于准确判断及正确处置螺旋、保证飞行安全具有理论指导意义。
About a certain type of aircraft is flying helical properties of the research has been more adequate, but its understanding of anti-helix is still very scarce. On the basis of the main flight parameters recorded in an anti-spiral flight accident of the aircraft, the anti-helical characteristics of the aircraft were analyzed by calculating the anti-helical dynamic parameters. The results show that the anti-helix of this type of aircraft belongs to a stable, steep, oscillating anti-helix. The proposed method of estimating helical characteristics provides a theoretical basis for the study and analysis of anti-helical characteristics using flight parameters, and is of theoretical significance for accurately judging and correctly disposing helices and ensuring flight safety.
