螺旋桨

His AERIAL LOCOMOTIVE, with a hydrogen-filled compartmented gas "spindle" 800 feet in length and 50 feet in diameter, was to carry between 50 and 100 people at a speed of 60 to 100 mph The great machine was to be remain aloft for 12 hours at a time, propelled by two steam engines driving two "fan wheels or propellers" each of which would be 20 feet in diameter and revolve at 200 rpm He estimated that the machine would weigh a total of some 14,000 pounds and would generate a total buoyant lift of 56,000 pounds, leaving 42,000 pounds for 200 passengers and luggage.

他的空中机车，与氢气填充compartmented气体&主轴&八百英尺在长度和50英尺，直径，是进行50至100人的速度在60至一百英里每小时伟大的机器是要继续高举12在一小时的时间，推进两个蒸汽火车驾驶&两个风扇车轮或螺旋桨&，其中每会20英尺，直径和旋转，在200 rpm的他估计，机器重量共约一四○○○磅，并会产生一个总蓬勃解除五六〇〇〇磅，离开四二零零零磅为200名乘客和行李。

After the rotor had been set in motion for vertical take-off, movement was transferred to a four-blade, dueled pusher propeller at the tail.

转子后一直在垂直起飞启动，运动转移到了四刀，决斗在尾推螺旋桨。

The Piper Cheyenne PA 31T twin Turboprop was first available in 1974 and was a direct development of the popular PA-31 Navajo piston engined twin.

该伯尔夏延坝三十一吨双涡轮螺旋桨是第一个可用的在1974年，是一个直接的发展，流行的PA - 31纳瓦霍活塞引擎双。

But I also knew how common it was for these lumbering giants to be gashed by boat propellers or entangled in crab traps.

但我也知道，它们这些笨拙的海洋生物经常被船的螺旋桨划伤，或卷入捕蟹器中。

The flying mechanism functions by helixes just like the ones of a helicopter and has already been developed in various ways.

飞行的机械结构是经由螺旋桨起作用，就好像直升机上的一样。

Inclosing the five cylindrical pontoons, which literally make up the hull, is a steel framework upon which is supported a 500-horsepower motor driving an airplane propeller.

inclosing五个圆筒形浮趸，这从字面上来看弥补船体，是钢框架后，这是支持了500匹马力的电动机驱动的螺旋桨飞机。

The body is partly levitated above the water surface, only the rear and the propeller remain in water.

身体部份是levitated以上的水面，只有后方的螺旋桨仍然在水里。

Piasecki says both objectives were met with a 47 percent speed increase on the same power and up to 50 percent lower vibration because lift and thrust is off-loaded from the rotor to the wing and Vectored Thrust Ducted Propeller.

皮亚塞茨基说，这两个目标是会见了百分之四十七的速度增加同样的权力和百分之五十，因为较低的振动升降机及主旨是卸货从转子的机翼和矢量推力涵道螺旋桨。

The error of the elongation is 2.3%, by the multi-dimension linear regression model, the relative error are from ? 5% to ? 15% respectively. Comparing the results, it can be found that the neural network overmatches the multi-dimension linear regression. So that, the model can be used in the production of the marine propeller aluminum bronze.

计算结果表明，三项输出的预测值与实测数据接近，抗拉强度和屈服强度的相对误差在±1％的范围以内，延伸率的最大绝对误差为2.3％，明显优于多元线性回归模型±5％—±15％的误差，能较好地满足工程应用的要求，对高强度船用螺旋桨铝青铜的生产具有一定的指导意义。

The after end of the hull is recessed to accommodate the propeller mechanism, which is in two cylindrical sections, one inside the other.

该结束后船体是休会，以容纳螺旋桨的机制，这是在两个圆筒形部分，一内其他。

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。
