Description

Die Erfindung betrifft eine Wirbelwindturbine mit senkrechter Drehachse und einem Rotorkörper. Das Turbinengehäuse ist drehbar gelagert und besteht aus einer 270-Grad-Ummantelung. Das Gehäuse besitzt drei strömungstechnisch geformte Windleitteile, die die Luftströmung in das Turbineninnere auf den Rotorkörper leiten. Weiter ist der Rotorkörper von einem auf der Rotorwelle sitzenden schmalen Innenzylinder umgeben, der die Wirbelbildung im Gehäuseinnern optimieren soll.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.

An der unteren und oberen Ummantelung sind je ein stumpfer Kegel installiert, um die Zu- und Abströmung des Luftwirbels strömungsdynamisch zu erhöhen.At the upper and lower shrouds each have a blunt cone installed, around the inflow and outflow the fluid vortex fluid dynamics to increase.

An der linken Gehäuseseite (von der Luvrichtung ausgesehen) ist ein Windstabilisator montiert. Das nach innen gewölbte Profil dient zur Windnachführung und stabilisert den Anströmwinkel in der Luvstellung.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.

Beim Rotorkörper handelt es sich um vier gleichgroße Flügelprofile, die senkrecht in Rechteckgeometrie ausgerichtet sind. Die Rotorflügel sind in 90-Grad-Abständen versetzt und über je zwei Rotorarme fest mit der Rotorwelle verbunden.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.

Die aerodynamisch geprägte Gehäuseform beschleunigt das Einströmen der Luft in das Turbineninnere. Die Folge ist die Erzeugung eines energiereichen Luftwirbels im Innenbereich der Turbine. So kann der Leistungswirkungsgrad des Rotors im Wirbelgehäuse massiv gesteigert werden.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.

Nachteile bei dieser Bauart entstehen, wenn die Flügelprofile des Rotorkörpers frei umströmt werden, weil die Bildung eines hochenergetischen Wirbels strömungstechnisch nicht funkioniert.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.

Die Aufgabe der Erfindung wird dann gesehen, eine Anordnung der anfangs genannten Bauart zu konstruieren, der den dargestellten Nachteil beseitigen soll.The The object of the invention is then seen, an arrangement of the beginning to construct the type mentioned, the disadvantage shown to eliminate.

Die Lösung der Erfindung besteht erfindungsgemäß dann, den senkrecht drehenden Rotorkörper mit einer strömungsdynamisch profilierten Turbinenform zu versehen. Diese 270-Grad-Ummantelung (in Kombination mit verschiedenen Strömungsleitprofilen) bewirkt die Generierung künstlicher Turbulenzen im Turbinengehäuse. Die Luft kann durch die konkave und konvexe Ausformung der Turbine (wegen der Wirbelbildung) schneller strömen. Ohne strömungstechnische Verkleidung verringert sich der Leistungswirkungsgrad bei freier Umströmung des Rotor extrem.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.

3: Perspektivische Gesamtdarstellung der Turbinenform, des Windstabilisators und der einzelnen Windleitprofile der Windturbine; 3 : Perspective overall view of the turbine mold, the wind stabilizer and the individual Windleitprofile the wind turbine;

Wie aus den einzelnen 1–3 zu ersehen ist, besteht die Wirbelwindturbine aus einem Rotorkörper mit vier baugleichen Flügelprofilen 3a–d, die über die Rotorarme 2a–h auf einer senkrechten, drehbar gelagerten Welle 1, sitzen. Weiter befindet sich der Rotor in einem 270-Grad-Rundgehäuse 6 mit aerodynamisch geformten Strömungsleitprofilen 7a–c. Die Windleitteile haben die Funktion, die Luftströmung ins Turbineninnere zu beschleunigen. Der rotierende Zylinder 4 im Innenbereich der Turbine bewirkt die Bildung eines leistungsintensiven Wirbels. So kann der Luftstrom schneller durch die Turbine strömen und die Rotorblätter in kräftige Drehbewegungen versetzen. Weiter begünstigt wird der Umlauf des Rotors durch die Abschirmung der linken (luvseitig gesehen) Turbinenhälfte. In diesem Bereich drehen sich die Flügel nicht mehr gegen den Wind, sondern befinden sich im Windschatten. Die Konsequenz ist eine Vergrößerung der Strömungsenergie der zirkulierenden Luftmassen.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.

Am oberen und unteren Turbinenende 6 ist an beiden Stirnseiten des Innenzylinders 4 je ein stumpfer Kegel 5a, b installiert. Die Zu- und Abströmung der Luftzirkulation wird im Turbinenbereich nochmals erhöht, bevor der Wirbel an die Umgebungsluft entweicht.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.

An der linken Gehäuseseite (von der Luvrichtung aus gesehen) sitzt außenseitig ein Windstabilisator 8. Dieses Teil ist nach innen konkav geformt, um die drehbar gelagerte Turbinenform dauerhaft in der günstigsten Anströmposition zu halten; d.h. die Turbinenöffnung befindet sich ständig frontal zur luvseitigen Windrichtung.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.

Die aerodynamisch ausgerichtete Turbinenkonstruktion verursacht einen schnelleren Durchlauf der Luftmassen, so dass die energiereichen Wirbel ihre ganze Leistungsintensität an den Flügelprofilen in kinetische Energie umsetzen. Die energetische Leistungsbilanz der ummantelten Turbine ist im Verhältnis zu einem freiumströmten Windrotor mit vergleichbarer Rotorfläche um ein Vielfaches besser.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.

Besonders eine vereinfachte, konsequente Leichtbauweise kommt hier zur praktischen Nutzanwendung. Weitere Vorteile sind eine extrem niedrige Anlaufschwelle, eine verschleißarme Rotorkonstruktion (keine Blattverstellung), Unempfindlichkeit bei Boenbelastungen und Geräuschlosigkeit aufgrund der Turbinenummantelung des Rotorkörpers.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.
