为了探究混合式CRP（contra-rotating propeller）推进器水动力性能，促进混合式CRP的工程应用，研究中以4000TEU集装箱船为对象设计了混合式CRP，在空泡水筒中对此混合式CRP的空泡性能进行试验研究。研究结果表明：混合式CRP前后桨转速比变化时，后桨对前桨的抽吸效果有所改变，从而改变前桨的空泡性能；混合式CRP桨叶的空泡面积会随桨叶与支柱相对位置的改变而改变，在不同位置前桨最大的空泡变化面积为整个空化面积的十分之一，同时后桨的来流由于前桨的影响，空泡面积被阻隔成不连续的两部分；混合式CRP 的前后桨尾流会相互影响，试验结果表明，尾涡运动较强的尾流会将尾涡运动较弱的尾流卷入，同时保持自己原有的运动轨迹下泄，而当两者尾涡运动强度相当时，尾流运动轨迹有较大程度的融合。“,”To study the hydrodynamic performance of a hybrid contra-rotating shaft pod ( HCRSP ) propulsor and to promote it for engineering applications, a HCRSP propulsor was designed for a 4000TEU container ship. Model tests of the cavitation performance were performed in a cavitation tunnel. Experimental results showed that the for-ward propeller cavitation changed with the revolution ratio of the forward and back propellers due to the suction effect of the aft propeller. The cavitation area of the blade was changed along with the change of the relative position between the blade and strut, and the maximum increase or decrease in the cavitation area was approximately one-tenth of the total cavitation area of the blade. Due to the influence of the forward propeller wake, the cavitation a-long the edge of the aft propeller was divided into two discontinuous parts. The wake flows of the aft and forward propellers influenced each other. The experimental result shows that the stronger wake flow scoops up the weaker, retaining its own downward path. However, the wake flows fused together when the strength of forward propeller wake vortex was roughly equal to that of the aft.
