摘　　要：为了探究阻塞环境对冰区桨水动力和空泡特性的影响,辅助冰区螺旋桨的优化设计,本文在大型循环水槽中搭建冰阻塞环境下螺旋桨水动力性能和空泡特性的测试平台,测量和观察常压和减压状态下不同冰桨阻塞参数时螺旋桨及单桨叶的水动力载荷和空泡形态。试验结果表明:冰阻塞条件下的螺旋桨水动力性能是由冰桨阻塞参数、空泡环境和螺旋桨运行工况综合作用的结果,在冰块阻塞效应和邻近效应、螺旋桨抽吸作用、冰块周围回流区以及“皮鲁埃特效应”综合影响作用下冰块和螺旋桨之间会诱发连体涡空泡并导致螺旋桨水动力性能剧烈波动。To explore the influence of the blocking environment on the ice-class propeller's hydrodynamic and cavitation characteristics and to help the optimization design of ice-class propellers,a test platform was built under the ice blocking environment in a large cavitation channel.The hydrodynamic loads of the whole propeller and a single blade were measured while cavitation patterns with different blocking parameters were observed under ambient pressure and depressurized conditions.The test results show that the hydrodynamic performance of the propeller under ice blocking conditions is the result of the combined effects of the ice blocking parameters,the cavitation environment and the propeller operating conditions.Under the combined influence of ice blocking effect,proximity effect,propeller suction,reflux zone and the"Pirouette effect",the conjoined vortex between the ice and the propeller blade will be induced and severe fluctuations are caused in the propeller's hydrodynamic performance.
