Abstract
Rotor-type super windmill based on logarithmic spiral-shaped load-bearing elements represents a single block of two vertical rotors having inverted curvature of load-bearing elements producing in the rotary mode in the inter rotor space circulation of velocity of both rotors in one direction and ensuring summation thereof with the velocity of the air flow.
Description
- U.S. patent application Ser. No. 12/342,311, filed Dec. 23, 2008 is incorporated herein by reference.
- Rotor-type super windmill and a method of increasing kinetic energy of air flow relate to wind power engineering and are meant for increasing kinetic energy of air flow to be further converted into mechanical energy.
- The super windmill is based on logarithmic spiral-shaped load-bearing elements forming in the body of the rotors the evenly convergent bending channels-air collectors. The elements simultaneously increase kinetic energy of flow due to increase of velocity of motion thereof in the convergent channels and produce geometric summation of forces resulting from the reaction of the flow moving in the bending channel/1, page 113-114/.
- These characteristics are embodied in the known rotor windmill (2).
- Known is the method of increasing kinetic energy of air flow by increasing velocity of motion thereof in the channels—air collectors as embodied in (3) by mounting coaxially in the center of the rotor windmill (2) an additional rotor of a substantially smaller diameter forming a low-pressure zone when it rotates in the centre of the rotor, the low-pressure zone drawing in with acceleration air mass of the flow through the channels-air collectors.

FIG. 1 is a diagram illustrating the rotors and airflow of a super windmill according to the present invention. - The present invention is aimed at developing a more efficient method of increasing kinetic energy of air flow as well as constructing the technical device for realizing the method and converting the flow of increased energy into mechanical rotation energy.
- It is known that when physical bodies rotate in air flow around them in the boundary layer around the contour of the rotated body there occurs circulation of some part of the flow whose velocity is summed up with the velocity of main flow on that side of the rotated body where these velocities are codirectional (1, pages 202-203).
- However the volume of air mass obtaining velocity gain is too small to find practical application.
- To achieve the set goal the authors created the technical device—rotor-type super windmill—which thanks to its structure alone ensures velocity gain to the large volume of air mass of flow.
- The essence of the invention consists in creating the inter rotor space between two vertical rotors with logarithmic spiral-shaped load-bearing elements having inverted curvature of surface in the rotors and ensuring in rotary mode in the inter rotor space velocity circulation of both rotors in one direction.
- The technical solution of the invention is presented in
FIG. 1 . - The air flow at the velocity Vf falls on the contour of the super windmill and cause
rotors inter rotor space 1 the circulation has the same direction and is codirectional with the velocity of the main wind flow. So in the inter rotor space these velocities are summed up to produce resulting velocity, i.e.: -
V r =V f +V 2 +V 3, - which makes up the essence of the method of increasing kinetic energy of air flow, mathematically expressed by the known formula:
-
- The motion of air flow at large velocity in the inter rotor space due to Bernoulli Law creates a vast low-pressure zone where under pressure of wind energy and atmospheric pressure all the air mass turns to, wherein the air mass falls on the contour of the structure of the super windmill rendering impact via its kinetic energy on the load-bearing elements of the rotors, thus setting the latter ones into rotary motion.
- The authors created and tested the model of said technical device. The test results proved high efficiency of the structure for converting the velocity of air flow and kinetic energy thereof into mechanical energy, which allows the authors to designate the invention with good reason as rotor-type super windmill.
