screw propeller

基本解释

Secondly this dissertation analyses two important parts-the screw propeller and the propulsion motor.
然后着重分析吊舱式电力推进系统的两个重要组成部分：螺旋桨和推进电机。
The aim of this paper is to give a more or less general treatment of vibration of elastic non-uniform strut, such as composite wooden screw-propeller.
本文以集合木制螺旋桨作为启示的出发点，从而想使弹性直杆振动问题能初步臻于一个比较更一般的处理。
He introduced them to DeBakey and Noon and they began work on an "axial flow" space-shuttle pump which contains a screw-like propeller sealed in a pipe.
将这三位工程师介绍给德贝基和农之后，他们就开始了对太空船“轴向涡流”泵的研究。这种泵的管道里有一个带有螺纹的转轴。

an early form of ship's propeller in which an Archimedes' screw is used to produce thrust by accelerating a flow of water
