Abstract

In order to analyze the interactions among various components of hybrid contra-rotating shaft pod (HCRSP) propulsor and effects of test devices, the model test of HCRSP propulsor was conducted in a cavitation tunnel. In the present study, the interactions among fore propeller, aft propeller, and the pod of HCRSP propulsor are analyzed with the influence of a long-axis dynamometer. It was found that the long-axis dynamometer shows great influence on the pod propulsor, which is made up of a pod and an aft propeller, but little influence on the fore propeller. Especially, under the condition of using a long-axis dynamometer or not, the difference of thrust coefficient and torque coefficient of the aft propeller with a high advance coefficient reached 10%. Also, the fore propeller could accelerate the flow of the pod propulsor. In detail, the pod and aft propeller show blocking and suction effects, respectively, and these impacts could cancel each other out within a certain range.
