直升机斜坡着陆试飞研究

Flight test research of helicopter slope landing

对直升机斜坡着陆试飞进行了探索和研究。首先进行了某型直升机斜坡着陆理论建模,分析和计算结果表明,直升机能够满足试飞要求;然后根据所设计的试飞方案进行了试飞验证。试飞结果表明,直升机具备足够的操纵安全余量是斜坡着陆成功的保证;所获取的逆坡着陆、顺坡着陆、左/右横坡着陆不同的驾驶技术和操纵策略,为编写飞行手册提供了可靠的依据。

Flight tests of helicopter slope landing is explored and researched in this article. First,modeling and analysis of helicopter slope landing theories show that the flight test requirements are reasonable,and then the flight test programs for helicopter slope landing is designed. As verified by flight tests,the sufficient operating safety margin is essential to successful helicopter slope landing,and obtain the different driving technique and operation strategy of the up slope landing,the down slope landing,the left / right slope landing,which is used to provide the credible evidence for writing the flight manual.
