民用飞机失速尾旋(螺旋)事故

Stall-Spin Accidents for Civil Aircraft

尾旋是飞机在失速后发生的一种特殊的旋转运动,此飞行状况常常导致飞机的失控坠毁,所以民用飞机在飞行中不允许出现尾旋。但由于种种原因,民用飞机尾旋事故还是时有发生。收集了以往民用飞机发生尾旋事故的实例,详细呈现了飞机尾旋的大致过程,为避免尾旋事故的发生提供参考依据。

Spin is a very complex rotational flight state when aircraft angle of attack is larger than stall incidence.This kind of flight state often causes aircraft loss control and prang,so civil aircraft is not allowed into spin state during the normal flight. Due to lots of reasons,spin accidents for civil aircraft still happen from time to time. This paper collects some cases of spin accidents for civil aircraft in the past,and clearly presents the approximately process of these accidents. This work is quite useful for avoiding the civil aircraft spin accidents.
