In the first, the background of this dissertation, the he status which helicopter blade dynamic balance experimental platform system design and using are introduced, helicopter blade dynamic balance experimental platform system is not designed in our country, so in this Dissertation, the advanced experience is accepted and some innovative methods also are used in the system design.

此论文通过借鉴国内外对直升机旋翼动平衡试验台系统设计的经验，确定采用当今较新与较成熟的技术构建了集数据采集与控制为一体的试验控制系统来满足整个动平衡试验的要求。另外还对直升机旋翼动平衡试验台系统方案设计中各分系统作了简单介绍，并通过和以往系统比较分析，在借鉴前人经验的基础上进行了创新。此论文主要介绍了直升机旋翼共锥度测量分系统的设计与实现。

The theoretical formulas for both a Hingeless and the Dolphin-2 Helicopter in maneuvering flight are derived in detail. Also analytical methods and calculating programs are developed.

全面推导了无铰旋翼直升机以及海豚型直升机的机动飞行计算公式，并建立了这两种类型直升机的机动飞行运动学和机动飞行动力学的理论分析方法和计算程序软件。

The most precarious of these quake-lakes was the one located in the extremely difficult terrain at Tangjiashan mountain, accessible only by foot or air; an Mi-26T heavy lift helicopter belonging to the China Flying Dragon Special Aviation Company was used to bring heavy earthmoving tractors to the affected location.[127] This operation was coupled with the work done by PLAAF Mi-17 helicopters bringing in PLA engineering corps, explosive specialists and other personnel to join 1,200 soldiers who arrived on site by foot.

在这些地震湖当中，最危险一个坐落在唐家山极其危险的地形当中，只能靠步行或者直升机才能靠近，一架隶属于中国飞龙特别航空公司的Mi-26T 重型起重直升机负责运送重型的挖土机到受影响区域，这次行动在中国解放军工程部队的中国空军Mi-17型直升机、爆破专家以及其他通过步行到达该地区的1200名官兵的协助下顺利完成。

The result is that last month the government, under pressure to show it was doing something to fix the shortage of battlefield lift, announced it was ordering 22 new Chinooks from Boeing, an American company, but not a single new Merlin from AW.

结果在上个月，英国政府迫于压力表示政府正在采取措施弥补武装直升机的短缺，并宣布将订购22架美国波音公司的新型奇弩克直升机，来自阿韦公司的默林直升机则一架也不订。

The results show that the flap hinge spring rate has a great effect on helicopter stability and control, but precone and prelag angle,lag hinge spring rate and blade lag motion can be negligible...

分析结果表明：旋翼的预锥角和预掠角对直升机全机的稳定性和操纵性的影响可以略去不计，而桨叶根部挥舞方向上的弹性约束刚度对直升机全机的操纵稳定性有较大影响，摆振方向上的弹性约束刚度和桨叶的摆振运动对直升机稳定性的影响不大，可以略去不计。

He first worked for Sikorsky Aircraft in the 1940s on helicopter design, later he worked for the American Helicopter Company on the design for a rotor-tip pulsejet powered helicopter for the US military.

他首先在工作了西科斯基飞机直升机设计的20世纪40年代，后来他为美国直升机公司合作为一个转子尖pulsejet为美军直升机供电设计。

McDonnell helicopter programs included the world's first twin-engine helicopter, the first ramjet-powered helicopter to fly, and the first aircraft to successfully transition from rotor-borne vertical flight to wing-borne horizontal flight.
