PBCF: A LOW-COST TECHNIQUE TO DIFFUSE HUB VORTEX

A short description is given of a propeller enhancement technique developed by Japan's Mitsui OSK Lines. The method for improving propulsive efficiency employs small fins cast into fixed-pitch propeller bosses. In essence it is a low-cost way to diffuse and weaken the hub vortex. The energy-saving possibilities have been successfully demonstrated. A controllable-pitch version is nearly ready.
