【摘要】 本文介绍了在减压拖曳水池中最新开发的桨模敞水试验技术。为研究和揭示高速船带空泡螺旋桨的水动力学特性，在变大气压力的情况下，开拓进行了两个半浸状态的桨模敞水试验。采用无线激光传输系统，桨模的敞水动力特性成功地在池外获取是本文所要介绍的新水池的关键技术。文中还提供了一些有价值的不同大气压力状态下的试验结果。更多还原

【Abstract】 A new propeller model open - water test was carried out in the decompressible towing tank .Tostudy the cavitation characteristics of the high speed propeller, the open -- water test of two partiallysubmerged propeller models in various decompressed conditions were specially done.Using laser wirelesstransmission system, the hydrodynamic characteristics of the propeller model was successfully off -- carriagecaptured. Some valuable comparisons of the results between different pressurs cases were presented in thepaper.更多还原
