Abstract

A turbulent wind turbine comprises a vertical rotating shaft (1) and rotor bodies with four equal vanes in a rectangular geometry fixed to the shaft by four double attachments. There is a 270[deg] covering sheath comprising three further convex flow guiding shapes and a concave wind stabilizer.

Description

  • The The invention relates to a whirlwind turbine with a vertical axis of rotation and a rotor body. The turbine housing is rotatably mounted and consists of a 270 degree sheathing. The housing owns three fluidic shaped wind deflectors, which the air flow in the turbine inside the rotor body conduct. Next is the rotor body of surrounded by a narrow inner cylinder seated on the rotor shaft, the vortex formation inside the housing to optimize.
  • At the upper and lower shrouds each have a blunt cone installed, around the inflow and outflow the fluid vortex fluid dynamics to increase.
  • At the left side of the case (looking from the wind direction) is mounted a wind stabilizer. The arched inwards Profile serves for wind tracking and stabilizes the angle of attack in the windward position.
  • At the rotor body it concerns four equal wing profiles, which are vertical in Rectangle geometry are aligned. The rotor blades are offset at 90 degree intervals and over two rotor arms firmly connected to the rotor shaft.
  • The aerodynamic Accelerated housing shape the influx the air into the turbine interior. The result is the generation of a high-energy air vortex in the interior of the turbine. So can the power efficiency of the rotor in the vortex housing massive be increased.
  • disadvantage In this design arise when the wing profiles of the rotor body free flows around be because the formation of a high-energy vortex fluidly not working.
  • The The object of the invention is then seen, an arrangement of the beginning to construct the type mentioned, the disadvantage shown to eliminate.
  • The solution The invention then according to the invention, the vertically rotating rotor body with a flow dynamic To provide profiled turbine shape. This 270 degree sheath (in combination with different Strömungsleitprofilen) causes the generation of artificial Turbulence in the turbine housing. The air can pass through the concave and convex shape of the turbine (because of vortex formation) flow faster. Without fluidic Fairing reduces the power efficiency at free flow around the rotor extreme.
  • 1 : Schematic representation of a fixed anchored square frame of the wind turbine, in the interior of a second square frame, is suspended rotatably mounted;
  • 2 : Perspective representation of Windleitströmungsteile of the turbine housing and the rotor body of the wind turbine;
  • 3 : Perspective overall view of the turbine mold, the wind stabilizer and the individual Windleitprofile the wind turbine;
  • As from the individual 1 - 3 can be seen, the whirlwind turbine consists of a rotor body with four identical wing profiles 3a -D, over the rotor arms 2a -H on a vertical, rotatably mounted shaft 1 , to sit. Next is the rotor in a 270-degree round housing 6 with aerodynamically shaped flow guide profiles 7a c. The wind guide parts have the function of accelerating the flow of air into the turbine interior. The rotating cylinder 4 in the interior of the turbine causes the formation of a power-intensive vortex. Thus, the air flow can flow through the turbine faster and put the rotor blades in strong rotational movements. Further, the circulation of the rotor is favored by the shielding of the left (windward side) turbine half. In this area, the wings no longer turn against the wind, but are in the slipstream. The consequence is an increase in the flow energy of the circulating air masses.
  • At the upper and lower turbine end 6 is on both end faces of the inner cylinder 4 one blunt cone each 5a , b installed. The inflow and outflow of air circulation in the turbine area is increased again before the vortex escapes to the ambient air.
  • On the left side of the case (seen from the windward direction) sits a wind stabilizer on the outside 8th , This part is concave inwardly to keep the rotatably mounted turbine mold permanently in the most favorable inflow position; ie the turbine opening is constantly facing the Windward wind direction.
  • The aerodynamically oriented turbine design causes a faster passage of air masses, so that the high-energy Whirl their entire power intensity at the wing profiles into kinetic energy implement. The energy balance of the jacketed turbine is in proportion to a free flow Wind rotor with comparable rotor area many times better.
  • Especially a simplified, consistent lightweight construction comes here for practical use turn. Further advantages are an extremely low start-up threshold, a low-wear rotor design (no pitch adjustment), insensitivity at Boenbelastungen and quietness due to the turbine casing of the rotor body.
