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.
Description
BRIEF SUMMARY OF INVENTION
[0001] The invention relates to a method of improving the efficiency of the blades on a propeller where water or air is pressurized in a chamber within the propeller blade. The fluid enters the chamber that is greater at its opening to a chamber, causing the fluid to exit through an exhaust opening in the trailing edge of the blade. The energy created by this exiting pressurized fluid is utilized by the additional thrust being converted to rotating the propeller and forcing it through the fluid, be it air or water at a greater force.

DETAILED DESCRIPTION OF THE INVENTION
Claims
- 1. A method for the enhancement and increased performance of a propeller/rotor, in the aquatic or atmospheric environment. In which the conventional blades have an additional surface added parallel to the existing blades plane from the leading edge to the trailing edge. An opening is created in the leading edge of said blades with the rear trailing edge being sealed. The rear face surface of all blades have a opening machined into the surface opposite and as close to the trailing edge as far behind the leading edge opening. The exhaust/out-flow opening to be approximately one/third (one/twentieth air) the size of the inlet opening. This opening is varied in ratio dependant upon the application and effect desired. This creates a pressure chamber for water/air being scooped into the created chamber. Forcing the water/air to exit the machined opening under much greater pressure. Therefore increasing the thrust and efficiency of the propeller being created. FIG. 1 (Aquatic)
The areas utilizing this improvement are: Marine propulsion, i.e.: Lower rated engines for the increased efficiency and greater speed produced, Increased fuel efficiency, Helicopter rotor blades producing increased lift, Light Aircraft propellers producing increased thrust, reduction of the vortex effect in turbo chargers.
- 2. Method according to claim 1, in which the design is to be utilized in the fresh or marine water or atmospheric environments.
- 3. Method according to claim 1, in which an additional chamber is added to the blades of a propeller/rotor. FIG. 1
- 4. Method according to claim 1, in which said Chamber on a parallel plane is added within the existing surface. FIG. 1, (Aquatic)
- 5. Method according to claim 1 in which said chamber on a parallel plane being created has an opening left along the leading edge. FIG. 1a & 2b (Aquatic)
- 6. Method according to claim 1, in which said opening is to allow water/air to be forced into the created chamber. FIG. 1(c) (Aquatic)
- 7. Method according to claim 1, in which said water/air is then pressurized by the restriction of the said chamber.
- 8. A device for carrying out the method of claim 1, Where the existing blade has a machined hole connecting the chamber as in claim 6 to the existing blade. FIG. 1 (Aquatic)
- 9. A device for carrying out the method of claim 1, Thus the opening connected to the chamber restricts and pressurizes the exiting water/air.
- 10. A device for carrying out the method of claim 1, Which the exiting water/air creates additional thrust.
- 11. A device for carrying out the method of claim 1, Where the exiting water/air also creates less drag.
