直升机旋翼自转着陆的安全性研究

旋翼自转是直升机一种特殊的飞行情况,在此情况下,旋翼失去发动机动力,只能利用其原有的旋转动能和直升机的势能保持稳定旋转。因此发动机停车后如何保证直升机自转着陆的安全性变得尤为重要,本文从理论上分析影响自转着陆安全性的几个因素,并就加强海军航空兵旋翼自转飞行训练的问题提出一些建议。

Helicopter Rotor Autorotation Landing Safety Research

Rotor autorotation landing is the inherent capability of helicopter in especial situation. While engine failured,the rotor would keep on rotating by its kinetic energy and helicopter potential energy with altitude.This paper presents the importance of safe landing in this kind of situation,and gives a theoretic analyses to the factors which may affect the safety in autorotation landing.Some suggestions are provided in the paper for helicopter flight training in Naval Aviation Division.
