摘要/Abstract

摘要： 针对L型吊舱推进器的结构特点自行研发了一套水动力性能测量装置，并利用船模拖曳水池实验室对其敞水性能进行了试验研究.试验测量了直航状态下进速系数在0～1.3内的螺旋桨推力、转矩以及吊舱推进器单元整体的推力和侧向力等相关性能，并对3个不同进速系数下L型吊舱推进器以0.1396rad/s的操舵速率进行动态操舵时的螺旋桨及吊舱整体的水动力性能与静态操舵时的水动力性能进行对比.研究发现，右旋桨L型吊舱推进器在向右动态操舵时螺旋桨整体上的推力要较静态操舵状态的大，而转矩偏小，吊舱单元整体受力变化较为复杂.

Abstract: In this study, an openwater measuring instrument was developed for Ltype podded propulsors and a series of experimental tests were conducted to evaluate hydrodynamic performances of the podded propulsor. Performance of propeller thrust, torque and overall thrust of the podded propulsor unit was measured in the experiment under the conditions of straight forward motion with the advance coefficient between 0 and 1.3. And a comparison of propeller and the podded unit performance under dynamic azimuthing conditions with an azimuthing of 0.1396 rad/s and static azimuthing conditions was made at three different advance coefficients of Ltype podded propulsors. The experimental results demonstrated that comparing with the static azimuthing conditions, propeller thrust in dynamic azimuthing conditions was larger but torque was smaller when the Ltype podded propulsor with righthanded rotation propeller turns right. The regularity of the variable force on the pod is very complex.

Key words: Ltype podded propulsor, model test, dynamic azimuthing, hydrodynamic, propeller
