吊舱式推进器模型试验方法中的一些问题

Some problems of model test methods for podded propulsor

近10多年来吊舱推进器在众多的船型上取得了成功的使用经验,预报其实船性能成为船东和设计部门关注的重点。文章介绍了吊舱式推进器的特点,分析了目前几种主要的吊舱推进器的模型试验方法及其特点,提出了在敞水、自航试验中需要关注的问题。

Podded propulsor has been widely used on many types of ship since last decade. However, the prediction of the performance of full scale podded propulsion remains to he a significant problem to both the shipowners and designers. The advantages of podded propulsor are outlined. Model test methods and advantages of several existing podded propulsors are presented, as well as the issues that should be taken account of in open water and selfpropulsion tests.
