某多发直升机自转着陆试飞方法

Autorotation Landing Flight Test Method of a Multiple-engine Helicopter

为评估某多发直升机自转着陆能力,掌握自转着陆试飞方法,开展了自转着陆试飞风险分析,建立了一套较完整的自转着陆试飞方法,并完成了自转着陆接地试飞验证。结果表明,所建立的自转着陆试飞风险分析和试飞方法可以用于指导直升机的自转着陆试飞和训练。

In order to evaluate the autorotation landing capability of a multiple-engine helicopter and master the autorotation landing flight test method,the risk analysis of autorotation landing test flight was carried out,a relatively complete method of autorotation landing test flight was established,and the flight verification of autorotation landing on the ground was completed.The verification results showed that the risk analysis and flight test methods established in this paper could be used to guide the helicopter’s autorotation landing flight test and training.
