螺旋桨

_-_AirExpo_Muret_2007_0184_2007-05-122531.jpg)
螺旋桨，有中央桨毂和辐射形桨叶的设备，每一桨叶都组成螺旋面的一部分。当它在水中或空气中旋转时，就产生拉（推）力，使船或飞机作前进运动。螺旋桨的拉（推）力与它作用的水或空气的质量和加速度的乘积成正比。要取得最有效的推进，质量应大而加速度应小。
英语百科
Propeller 螺旋桨
A propeller is a type of fan that transmits power by converting rotational motion into thrust. A pressure difference is produced between the forward and rear surfaces of the airfoil-shaped blade, and a fluid (such as air or water) is accelerated behind the blade. Propeller dynamics, like those of aircraft wings, can be modelled by either or both Bernoulli's principle and Newton's third law. A marine propeller of this type is sometimes colloquially known as a screw propeller or screw, however there is a different class of propellers known as cycloidal propellers - they are characterized by the higher propulsive efficiency averaging 0.72 compared to the screw propellers average of 0.6 and the ability to throw thrust in any direction at any time. Their disadvantages are higher mechanical complexity and higher cost.
