直升机

The CH-47 Chinook cargo helicopter of US Boeing is very easy to identify. In other words, it looks quite strange.

美国波音公司的 CH-47"支努干"运输直升机是一种很好辨认的直升机，因为它的外观很奇特。

Above all results are of significance in order to study stability and control on coaxial helicopter in future.

在直升机动力学的研究中，准静态假设是一种有效的研究方法，在直升机的分析

Cryo Copter -$1600 -- This is a support helicopter.

严寒直升机——1600——这是个支援直升机。

Based on the similarity theory, two degrees of freedom flight test platform was designed to simulate the helicopter, then the platform was taken as the research object, and the Lagrange-Euler equation and the equivalent moment method were used to derive the system dynamics model, and the physical parameter was estimated.

基于相似性理论设计了具有两自由度的直升机飞行模拟试验平台，以该试验平台为研究对象，利用拉格朗日一欧拉方程与等效力矩相结合的方法推导出系统的动力学模型，预估了试验平台的物理参数；通过试验获得在固定总距角情况下直升机的升力随转速的变化关系。

Fabre said he was looking to Asia for increased sales in the next 30 years, pointing that China only has around 600 helicopters but could see equal the 6000 or so helicopters operating in the United States in the next three decades. In 2009 60 of engines were to replace old engines, with 40 % new sales, Fabre believes that by 2039, 60 % of sales would be for new engines.

法布尔说，他希望亚洲在未来30年增加销售，指出中国目前只拥有大约600架直升机，但同样可以看到，在未来3年有6000多架直升机在美国工。2009 年，60%发动机销售是替换旧发动机，40％是新机销售，法布尔后认为，到2039年，销售额的60％将是新机销售。

Development of flight control system has already caused much attention of many countries.

无人直升机的飞行控制系统是无人直升机研制中的重要环节。

In addition, the difference between forward flight and hover makes the controller design much more difficult too.

另外，直升机悬停与前飞之间较大的特性差异也是使直升机控制系统更加困难的特点之一。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
