摘　　要：本文针对一型浸没式喷水推进船模和一型螺旋桨对标母型船模,开展推进器敞水试验、船体阻力试验与自航试验研究,系统分析两种推进方式对应的推进器本体、“船体-推进器”系统推进性能的差异与变化特性。研究结果表明:(1)浸没式喷水推进器模型尺度下的敞水效率与螺旋桨相当,最高效率达到0.72,且高效工况区范围更宽;(2)相较螺旋桨推进船,浸没式喷水推进船的艉部附体少、布置简洁,显著减小了附体引起的船体阻力增加;(3)浸没式喷水推进船模在Fr=0.20与Fr=0.26二种典型工况自航条件下的推进效率分别为64.7%和66.1%,分别高出螺旋桨推进对标船模1.2和5.3个百分点,对应于浸没式喷水推进器的主机功率较螺旋桨分别下降9.41%和15.4%,浸没式喷水推进船具有更好的快速性与节能效果。该研究可为高效低噪的高速排水型船舶新型泵类推进器研制及“船体-推进器”一体化优化设计提供有益的技术参考。Propeller open water tests,hull resistance tests and self-propulsion tests were carried out on two ship models propelled by submerged waterjet and conventional propeller respectively.Detailed analysis was done on the variations of propulsive performances of the submerged waterjet,propeller as well as corresponding hull-propulsor systems.Results show that:(1)the propulsive efficiency of submerged waterjet in open water is equivalent to that of the propeller in model scale,with the maximum efficiency around 0.72,while the high-efficiency operation range of submerged waterjet is wider than that of propeller in open water;(2)compared with propeller ship,the simpler stern-appendage arrangement of submerged waterjet ship can effectively reduce additional hull resistance caused by stern appendages;(3)at Fr=0.20 and Fr=0.26,the overall propulsive efficiency of submerged waterjet ship model in self-propulsion is 64.7% and 66.1%,which is 1.2% and 5.3% higher than that of propeller ship respectively.The corresponding absorbed power of the submerged waterjet is 9.41% and 15.4% lower than that of the propeller at two speeds respectively.Generally,the submerged waterjet propelled ship shows a better performance of propulsion and energy saving.This study provides a meaningful reference for the integrated design and optimization of submerged waterjet and its corresponding hull geometry.
