Abstract: A method for the enhanced performance of a propeller/rotor. In which the conventional blades have been modified by the addition of a surface parallel or a cavity created within the existing blade plane from the leading edge to the trailing edge, encompassing the complete blade. An opening is created in the leading edge of blades with the rear trailing edge being sealed. The trailing face of the blades have a opening machined into the surface opposite and as close to the trailing edge, and as far behind the leading edge opening. The opening (exhaust) location maybe relocated to achieve different desired effect. The created chamber causes the water/air entering to be pressurized after being scooped into the chamber. Forcing the water/air to exit the machined exhaust opening under far greater pressure. Therefore increasing the thrust and efficiency of the propeller.
