螺旋桨

Propeller design is a vital part in ship design.

螺旋桨设计是船舶设计中的一个重要组成部分。

So, an in-depth study in how to make an accurate prediction of the hydrodynamic performance of the propeller is very important.

因此，深入地研究如何准确地预报螺旋桨的水动力性能是非常重要的。

Even a propeller has a diameter much larger than its blade width and thickness, etc....

甚至螺旋桨有一个直径远远大于它的叶片宽度和厚度等。。。

And give an automatic method of estimating propeller shaft frequency in this paper.

给出了一个自动估计螺旋桨轴频方法。

DPS is a rather complicated system,as each Z type propulsor has its own computer chips and remote controller for recieving the signals from PID system during the period of the model experiment.

由于DPS是一个较为复杂的系统，在进行模型试验时，每个Z型螺旋桨都设有计算机芯片以及遥控装置，用以接收PID系统发出的指令，为模型试验的模拟也带来了一定困难。

Calculation results show that through interaction characteristic optimization, the efficiency of the integrated propulsor can be dramatically increased compared with individual propeller under the same thrust load coefficient.

计算结果表明，与单独螺旋桨推进器相比，在同样的推力负荷下，干扰特性优化可使组合推进器敞水效率大幅度地提高。

DPS is a rather complicated system,as each Z-type propulsor has its own computer chips and remote controller for recieving the signals from PID system during the period of the model experiment.This causes certain difficulties for the simulation of the model experiment.

Directly behind is the Prowler, but what are the two propeller ?

直接起因是徘徊者，但有两个螺旋桨

I have been doing quite a bit of research on propellers as that is the next main thing for me to work on.

我已做相当多的研究螺旋桨，这是未来主要的事，我的工作。

This version adds propeller propulsion, apparently using a three-cylinder air-cooled radial engine.

这个版本增加了螺旋桨推进，显然是用3缸风冷式径向引擎。

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。
