Improvements introduced in the propellers of ships characterized by the fact that it consists in practicing in the propeller a series of grooves through which the injected air exits from inside the tubes of the axis of rotation thus facilitating the creation of a lower density in the mass of water surrounding the propeller largely bypasses the advancing resistance of the rotation that the suction of the water produces on the back of the propeller.
