螺旋桨叶

飞机在积冰气象条件下飞行时，容易发生积冰的部位有：机翼、尾翼、螺旋桨叶、发动机进气道前缘、风挡、空速管、天线等。

When flying in icing weather conditions , the areas of aircrafts prone to ice accretion are : airfoil , tail , propeller blade , leading edge of engine inlet , windshield , pitot , antenna and so on .

从轴心向后倾斜的螺旋桨叶；使船的桅杆倾斜我可以把座位向后倾斜吗？

Propeller blades that rake backward from the shaft ; rake a ship 's mast . May I put my seat back ?

飞机引擎和直升机的螺旋桨叶会不停地被空气中的沙尘磨损，减慢这种磨损的方法会大有用武之地。

Aircraft engines and helicopter Rotor-Blades are constantly abraded by atmospheric dust , and a way of slowing down this abrasion would be welcome .

该模型可用于含初始缺陷或意外损伤的螺旋桨叶无限寿命可靠性分析和设计，得到桨叶可靠度与初始裂纹尺寸之间的函数关系式。

The model is applicable to the reliability analysis and design of infinite life for propeller blades or other structural members with initial defects and accident damage .

由于船体的影响，双桨船的螺旋桨处于斜向来流的条件下运转。斜流造成螺旋桨叶工作状态的非定常性。

Because of the influence of the hull , the stern propeller of a twin-screw vessel is working under condition of oblique flow , and the unsteady working condition of the blade of a propeller is created .

对扑翼的非定常流场，传统的定常涡格法已不再适用。桨毂的影响以布置在其表面上的面源分布来模拟，螺旋桨叶采用离散的涡格法来处理。

For the strongly unsteady characteristic of the flow field of flapping-wing , the traditional vortex lattice method is not more effective . A surface source distribution is used to replace the boss and the vortex lattice representation of propeller blader is also incorporated .
