倾斜尾桨直升机侧滑-俯仰耦合研究

Research on Sideslip-Pitch Coupling of Canted Tail-Rotor Helicopter

针对倾斜尾桨直升机的侧滑-俯仰耦合进行了分析研究。首先描述了倾斜尾桨直升机在横侧静稳定性模拟试飞中出现的侧滑-俯仰耦合现象;进而分析了该耦合产生的机理,给出了该耦合的主要影响因素;最后对该耦合的解耦方法和试飞评估方法进行了研究。研究结果可为倾斜尾桨直升机侧滑-俯仰耦合的试飞与评估提供重要参考。

This paper introduced and researched sideslip-pitch coupling of canted tail-rotor helicopter. The phenomenon of sideslip-pitch coupling occurred during lateral-directional static stability simulated flight test was described firstly, Then analyzed the mechanism of this coupling, and gave the main influencing factors of it, At last, the decoupling methods and flight test and evaluation methods of this coupling were studied. The conclusions in this paper provide important reference for flight test and evaluation of sideslip-pitch coupling of canted tail-rotor helicopter.
