This disclosure is related with propeller noise and cavitation abatement in applications like propulsion, ventilation, pumping or turbine systems on liquid or gas fluids working like a propellers, pumps, fans or turbines, by novel techniques that allows a stronger propellers and improves laminar flow and allow a smooth acceleration or deceleration of the liquid or gas by means of a propeller that consist on a rotating cylindrical block with one or more tunnels around it axis, said cylindrical block also may have flow separators structures at both input and output that helps to keep laminar flow of the fluid or gas with it surrounding media, having This rotating cylindrical block tunnels with either circular or irregular oval section that accelerates fluid or gas by means of both combined centrifugal and axial movement.
