查询词典 propeller

With the fund item sponsored by the National Laboratory of Hydrodynamics, the study on measurement method of propeller-induced pressure with using self-propulsion model has been carried out in depressurized towing tank.

在脉动压力的模型测试研究方面，本文在水动力学国家重点实验室基金项目的资助下，对在减压拖曳水池中利用自航模进行空泡螺旋桨诱导的脉动压力的测试方法进行了研究。

A maneuvering mathematical model for controllable pitch propeller ships with three degrees of freedom was established according to separate modeling theory to simulate ships' maneuvering motion in ship-handling simulator.

0引言为获得良好的船舶操纵性能，大多数客船、拖网渔船、军舰等都采用可调螺距螺旋桨作为其推进方式。

The vessel to be propelled by a single-acting two stroke supercharged cross head Diesel engine, acting to a fixed pitch propeller.

该船的主机为单作用，二冲程，带涡轮增压器的十字头柴油发动机，并且螺旋桨为定距桨。

For the capacity of propeller turbine is often small, people pay little importance on the transformation of reducing capacity under specified conditions. So, nowadays little research mentioned above has been developed.For the particularity of the designed factors, the author has improved the traditional theory, and has fined an available Method of singular point distribution. At present, no one has developed CAD hydraulic design software of lower specific speed axial flow runner in our country.

由于设计条件的特殊性，在研究设计方法过程中，论文基于传统设计理论，对引用的一些基本规律做了一定改进，在具体设计过程中，对经验参数的选择方法做了一定探索，研究与探索运用奇点分布法设计低比转速轴流式转轮叶片；传统的设计工作全部由人工完成，无法满足当今社会科技生产发展的需要，因此论文开发了一套具有人机对话界面良好特点的低比转速轴流式转轮CAD软件。

Obviously this is only possible if the engine is still running and the propeller slipstream blows over the horizontal tail.

显然，这是唯一可行的，如果发动机仍然在运行和螺旋桨汇集的冲击超过平尾。

The test results indicates that the loss of energy in propeller slipstream is certainly reduced by adding vane wheel.

在船舶节能技术中，回收螺旋桨尾流能量来增加螺旋桨推力的导轮装置是一项具有发展前途的技术。

Rudder that is located in the slipstream of the propeller.

螺旋桨的滑流区。

Control would be achieved by deflecting part of the slipstream emerging from the tail boom and use of the propeller flaps.

控制将所取得的偏转部分的Slipstream摆脱尾巴繁荣和使用螺旋桨的皮瓣。

Stabilizer in the slipstream of the propeller. We will go back on the use of the horizontal stabilizer later on.

因为旋翼机通常速度并不是很高，所以最好将水平尾翼螺旋桨的滑流区。

On a "tee" tail configuration, the propeller slipstream has very little effect on the horizontal tail.

关于"三通"尾巴配置，螺旋桨汇集很小，对平尾）。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
