Dispositivo a recupero di energia per elica da navi
PBCF
PBCF Propeller Boss Cap Fins
Regardless of the type of vessel screw propeller*, approximately 10% of the shaft horsepower is not avoidable from the hub vortex energy loss.
(*excluding counter-rotating propellers, Grim vane wheels, etc., with hub vortex countermeasures).
Therefore, the PBCF is also effective with vessel screw propellers regardless of the type or hull form of the vessels.
