tandem propellers

This paper presents the results and analyses of open water tests of tandem propellers in a nozzle of accelerating flow type.

本文叙述了加速导管中串列螺旋桨敞水试验结果及分析。

The two counter-rotating tandem propellers provide a simple means to enhance yaw control, which is particularly important in vertical flight.

而机上安装的一对反向旋转的螺旋桨则起到了至关重要的作用。

The Preliminary Application of Tandem Propellers to River Ships

串列螺旋桨在内河船上的初步应用

A simplified theoretical method for calculating tandem propellers

串列螺旋桨的简化理论设计方法

A simplified theoretical method for calculating tandem propellers is presented in this paper.

本文提出了一个串列螺旋桨的简化理论计算方法。

The calculation and the full scale test show that it becomes feasible for river ships to use tandem propellers on the channels with shallow water and many shoals and rapids.

计算及实船试验表明：在水浅、流急、滩多的内河航道上，船舶采用串列螺旋桨，是现实可行的较好的推进方式之一。
