急盘旋下降问题的研究

Research on the Problem of Sudden Spiral Dive

从盘旋下降的运动关系入手,分析了飞机进入急盘旋下降的根本原因。推导出了进入急盘旋下降的极限坡度变化率的计算公式。此文侧重于进入急盘旋下降原因的介绍与分析。

First, this paper starts with the movement relation of spiral dive, analysing the crucial cause why the plane begin to dive as soon as it enters into the sudden spiral. Second,it deduces changing rate formula of extreme angle of bank when it enters into sudden spiral dive. This paper mainly emphasizes in introducing and analysing to the falling cause of sudden spiral' s entry and plays some certain theoretical guidance role preventing the plane from entering into sudden spiral falling as well as in assuring aerobatics fling safety.
