Abstract
This invention is directed toward a propeller with one of more propeller blades. The propeller blades have some combination of a sharpened leading edge, one or more steps on the upper or lower surface of the propeller blade, and an “S” shape. The combination of these radical changes from traditional propeller design creates a quieter, more efficient propeller that has applications on any device that uses propellers: from quadcopters and airplanes to boats and fans. Propellers with one, two, three, four, five and more propeller blades are contemplated depending upon the substance the propeller is intended for use in.
Claims20
A propeller, where the propeller consists of two propeller blades, where each propeller blade has an “S” shaped curve, where the “S” shape curve has an angle, where each propeller blade consists of a leading edge, where the leading edge is a sharp leading edge, a trailing edge, a top surface and a bottom surface, and a propeller depth, where the top surface has a step, where the step comprises a rapid decrease in the propeller depth from the leading edge to the trailing edge, where the propeller has an efficiency and an amount of noise that is generated by a rotation of the propeller, where when air flows over the top surface of the propeller blade, a vortex is created behind the step, and where the vortex forces a quantity of air in a downward direction at the trailing edge of the propeller blade, thereby increasing the efficiency of the propeller, where the vortex forces a quantity of air in a downward direction at the trailing edge of the propeller blade, thereby decreasing the amount of noise from the rotation of the propeller, where the angle is greater than 90 degrees.
A propeller, where the propeller comprises at least two propeller blades, where each propeller blade has an “S” shaped curve, where the “S” shape curve has an angle, where each propeller blade comprises a leading edge, a trailing edge, a top surface and a bottom surface, and a propeller depth, where the top surface has a step, where the step comprises a rapid decrease in the propeller depth from the leading edge to the trailing edge.
A propeller blade consisting of:
- a leading edge, a trailing edge, a top surface and a bottom surface, where the top surface has at least one step in it.
