POD-TYPE PROPULSION SYSTEM INSTALLED PROPELLER BOSS CAP FIN

摘要

It include hub cap fin the present invention relates to a kind of podded propulsor, more specifically, being related to a kind of podded propulsor includes hub cap fin, it removes the propeller generated when propeller hub vortex turns, improve propulsive efficiency, by the entire propeller for reducing torque, inhibit to generate the vibration of propeller hub whirlpool bring and noise, reduces the operation of required energy consumption. The podded propulsor includes that hub cap fin includes: pillar, is installed in a hull, to be able to carry out rotation; These container bodies are mounted on strut; Propeller, which is fixed, is placed in container body in rotary shaft, to generate propulsion rotation connection; It include that multiple tail fins are placed on rotation axle portion or propeller with a hub cap fin. ;The 2014 of copyright KIPO submissions
