水动力试验技术在全回转三桨推进船上的应用

Model Test Techniques for Triple Screw Vessels with Azimuth Thrusters

随着海洋工程的不断发展,一大批新型具有动力定位功能的船舶应运而生,其中不乏采用全回转推进方式的船舶。在以往,由于试验条件不足,对于此类船型,特别是采用多桨推进以及全回转推进船型的水动力试验无法进行。不过随着试验技术的不断发展和完善,现已具备对配置三桨全回转推进的船舶进行模型水动力试验的能力。通过对一艘三桨全回转推进船的模型试验研究,解决了此类船舶的快速性试验问题,其结果可为船厂和设计单位提供参考依据。

With the development of offshore projects, lots of new kinds of ships equipped with the dynamic positioning function are built. These ships usually use several azimuth thrusters. It was difficult to perform model tests for multi-screw vessels with azimuth thrusters due to lacking of appropriate test facilities. The advances have been achieved both in test technology and e- quipment development for such tests. The SSSR/ is now capable of performing those hydrodynamic tests for ships equipped with azimuth thrusters, up to three sets of them. This paper describes the model tests of a ship with triple azimuth thrusters studying the powering performance of the ship. The results can provide referenee for shipyards and design offices.
