螺旋桨

In 1934, Nagler brought out his Heliogyro which had a 90hp Pobjoy radial air-cooled engine, a two-blade rotor and a pusher propeller.

1934年，带出了他的Heliogyro Nagler其中有90hp宝来径向风冷发动机，双转子叶片螺旋桨和推动者。

The airplane propeller follows a specific path , but as it approaches the radio wave is spinning vertically .

飞机螺旋桨如下一个具体的路径，但因为它的办法无线电波是纺纱垂直。

The measurement of screw propeller is an important procedure in its manufacture.

螺旋桨的测量是其制造过程中一个很重要的工序。

Also let us adjust the size or pitch of the screw propeller, then try to get high-speed running.

也让我们调整大小或摊位的螺旋桨，然后尝试获得高速运行。

. The screw propeller is very efficient for push water.

在螺旋桨是非常有效的推水。

I'm not a triple screw propeller.

就是这样。我可不是一架三翼螺旋桨。

. It is easy to adapt to the Stirling engine boat, but the propulsive force is lower than that of the screw propeller.

人们很容易适应斯特林发动机船，但推进力是低于螺旋桨。

Vector control is the foundation of high performance PMSM control system Every vector control is analyzed and compared and several system characteristic are studied with special screw propeller load in this thesis, and then it is put forward that optimal torque control is the best control method of PMSM propulsion system.

本文对现有的几种矢量控制进行了深入的分析和比较，并结合推进系统特殊的螺旋桨负载研究了系统的各种特性，提出把转矩最优控制方案应用到舰船永磁同步电动机推进系统中。

In the past, cycloidal propellers have not been well applied because their construction costs were higher than that of screw propeller, and the progress of investigation on the hydrodynamic characteristics about cycloidal propeller was slow.

在过去的年代里，由于摆线推进器的造价要比一般螺旋桨高得多，一直没能得到很好的应用，有关摆线推进器水动力性能的研究也一直进展缓慢。

And the main content of this paper is as the following:(1) The establishment of matching calculation platform of screw propeller and diesel engine.

柴油机是船舶的主要动力来源，螺旋桨是推进船舶前进的执行机构，二者性能的好坏以及匹配效果如何将直接影响到船舶的营运经济性能和航行安全性能；船舶冷却系统是柴油机高温受热部件正常、高效运行的重要保证，冷却系统的设计与选型适当与否将直接决定主机功率能否充分发挥。

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。
