Propeller control flow cap

Simple structure, easy installation
Low cost, quick recovery of cost
Utilizing of rotating flow from propeller, to increase the shaft torque and improve the propeller efficiency, reduce the energy loss
Reduce the vibration and noise cause by the propeller
Suitable ships with our current design.
Medium-low Speed Ship, especially for Big Tail Ship and for those ships with uneven flow
Ships with propeller of big vortex, large pitch etc.
