At first, the kind of high-speed craft and its current situation are introduced in this paper. Through analyze and compare the characteristics of their performance, three kinds of high-speed craft are selected to be optimized. They are hydrofoil-gliding craft, wave-piercing catamaran and frigate, which power equipment of propulsion system are the common screw, pitch-adjustable screw and water-jet propeller.

本文首先介绍了高速船种类及其推进器的发展现状，通过分析比较各种船型的性能特点，选取了三种典型的高速船(翼滑艇、穿浪艇和护卫舰)并分别以普通螺旋桨、可调距螺旋桨和喷水推进器作为三种船型等动力装置。

So this paper takes the middle speed and small power of ship diesel engine as research object, and with the title of the matching research of ship diesel engine with screw propeller and the optimized design of cooling system to research the matching design of ship power system. And the main content of this paper is as the following:(1) The establishment of matching calculation platform of screw propeller and diesel engine. This paper starts with the analysis of balance of ship energy, and gets energy transfer relationship between ship diesel engine and screw propeller.

为此，本论文以中速小功率船舶柴油机为研究对象，以船舶机桨匹配与冷却系统优化设计为题进行船舶动力系统匹配设计研究，主要内容有：(1)船舶机桨匹配设计计算平台的建立本论文基于船舶能量平衡问题分析，推导螺旋桨与船舶柴油机之间能量传递关系，分析螺旋桨与柴油机的匹配设计。

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