The original engines were replaced in the Mk III by two Merlin IV engines rated at 1030 hp at 16,000 feet that drove three-blade constant speed Rotol propellers.

原来的发动机改为在马可福音三两个梅林四发动机额定在1030年惠普在一点六万英尺驱使三刀片恒速Rotol螺旋桨。

The effect of bubbly layer on propulsion performance of planing craft is investigated by means of self- propelled model experiment in the towing tank of China Ship Scientific Research Center.The results show that bubbly layer has small effect on propulsion performance of planing craft model propelled by water skew propeller.

在中国船舶科学研究中心拖曳水池中，通过滑行艇模型自航试验，研究了艇底气层对滑行艇推进性能的影响，结果表明：气层对采用水螺旋桨推进的滑行艇推进性能的影响不大。

Behind the wing a long and slender tail boom hid the drive shaft, which extended past a cruciform tail to a four-bladed wooden propeller.

传动轴隐藏在后面一段细长的尾部机体中，机体一直延伸到十字尾部最后再到刀刃形状的木制螺旋桨。

The tail boom tapers from the main body to the swept-back, tapered fin with a rotor on the right. Two flats are mounted on the both side of the boom.

尾梁从机身渐细到后掠尾垂翼，尾螺旋桨在锥形尾垂翼右侧，二个尾平翼被装在尾梁两侧。

艉框架为焊接组装式钢结构，与铸钢制的螺旋桨毂构成一体。

Stern frame to be shaped to obtain sufficient clearance of the propeller and obtain smooth streamline.

艉部结构应建造成能使螺旋桨有足够净空间并获得光滑流线的形式。

Based on the characteristics of twin stern hull form of a fast speed passenger ship, this paper carries out the theoretical design and experimental research of energy saving appendages around the flow field of screw propeller.

针对双尾快速客船的船型特点，以具有典型性的优良船型为母体，围绕螺旋桨流场，进行导轮、尾框鳍、舵球等附体的理论设计与试验研究，探讨适用于内河快速客船的几项附体节能技

It possesses unusual stability largely because of the care with which the propeller was placed after a series of experiments --- about one-third of the way back from the bow of the boat to the stern.

它具有不寻常的稳定，主要是因为照顾与螺旋桨被放到经过一系列的实验---约三分一的方式，回到从船头船严峻。

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。
