摘　　要：为提高对转桨的推进性能,减小空化效应,将端板螺旋桨应用于对转桨,分析端板型对转桨的片状空化性能和推进性能。基于RANS及Schnerr-Sauer空化模型,对由常规侧斜螺旋桨组成的对转桨和端板螺旋桨组成的新型对转桨,在系柱及低进速下进行空化性能分析及推进性能校核。研究发现:端板的添加使对转螺旋桨具备更佳的抗空化性能,系柱状态下(J=0)桨叶表面片状空化范围减小约59%,J=0.1时空化延迟发生;且在低进速条件下,端板对转桨具备更高的推进效率,较常规侧斜对转桨高出0.9%~3.1%;在不同转速下,端板型对转桨的敞水仿真结果与实验数据较为吻合。本研究将端板螺旋桨创新性地应用于对转螺旋桨,适合于低速潜航器的推进及作业需求。In order to improve the propulsion performance of contra-rotating propellers and reduce the cavitation effect,an end plate was applied to the contra-rotating propeller.The cavitation performance and propulsion performance of the end-plate contra-rotating propeller were analyzed.The RANS method with Schnerr-Sauer cavitation model was used for analyzing.Then the propulsion performance of contra-rotating propellers composed of conventional skewed propellers and end-plate propellers were checked for comparison.It is found that the addition of an end-plate makes the contra-rotating propeller possess better anti-cavitation performance.The sheet cavitation range is reduced by about 59%in the bollard state(J=0),and the cavitation is delayed when J=0.1.In addition,under the condition of low advance speed,the end-plate contra-rotating propeller shows a higher propulsion efficiency by 0.9%~3.1%than the conventional one.The open water performance of the end-plate contra-rotating propeller was tested at different rotation speeds,and the data were in good agreement with the simulation results considering the cavitation model.In this study,an end plate is innovatively applied to the contra-rotating propeller,which is suitable for the propulsion and operation requirements of low-speed submersibles.
