螺旋桨

These engines deal with larger comparative airflows and lower jet velocities than the pure jet engine, thus giving a propulsive efficiency (Part 21) which is comparable to that of the turbo-prop and exceeds that of the pure jet engine fig.

因而，其推进效率(第21章)与涡轮螺旋桨的相当，超过了纯喷气发动机的推进效率(图1-lO)。

The form as follows is the sales budget for our main product airscrews, axle helm when the new Company return to normal operations.

As for airships, they are driven by propellers and must maneuver to hold position against the wind.

至于飞艇，它们采用驱动螺旋桨，必须不断调整位置抵抗风力。

A computational method for prediction of pressure fluctuation induced by cavitating propeller on hulls of arbitrary shape is reported.

When approaching the city of Lethbridge from Calgary in a small propeller plane, it is immediately apparent how the great rift of the Oldman River valley, with its environmentally sensitive coulees, cuts the city into two halves.

坐在一架小型螺旋桨飞机里从卡尔加里市向莱斯布里奇市逼近时，老人河峡谷的裂口之大立刻就显现出来了，它以那对环境敏感的斜壁干谷，将该城市切成了两半。

The Villain EX is equipped with a new propeller design.

But no wings, no rotor, no propeller, no jet, no rocket...

但没有翅膀，没有转子，没有螺旋桨，没有喷射，没有火箭。。。

I like jet planes, propeller planes, helicopters, rockets, spacecraft and spaceships… all things that can fly.

我喜欢喷气式飞机、螺旋桨飞机、直升机、火箭、宇宙飞船及航天器，总之，一切能飞的东西。

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。
