Abstract

A carousel is pivoted on a cylinder supported on a base. The carousel turns on the base on gear wheels running on a circular rack on the base. The carousel carries tangentiale blower type turbine wheels on a horizontal axis. A wind vane provides an input to a servo system which turns the carousel so as to bring the wheels into the wind. The output is controlled by a shield which is raised to obscure more or less of the face area of the wheels. The shield is controlled by a servo system from a wind-speed meter.

Die Leistung von 10 KW ist abhängig von einer mittleren Windgeschwindigkeit von 4,5 m/s.The power of 10 KW depends on an average wind speed of 4.5 m / s.

GROWlAH ist ein Prototyp von Großwindanlagen mit der die Nennleistung ron 3HW bei einer mittleren Windgeschwindigkeit von 12 m/s und einer Winaauffangfläche von ca. 300 m angegeben ist.GROWlAH is a prototype of large wind turbines with rated power of the ron 3HW at an average wind speed of 12 m / s and a Winaauffangfläche is indicated of approximately 300 m.

Das bedeutet, 10 KW pro 1m2 Windauffangfläche.That means 10 KW per 1m 2 wind catchment area.

Diese Anlage ist jedoch zu aufwendig um größere Energiemengen zu erzeugen.However, this system is too expensive to generate larger amounts of energy.

Um eine Leistung von 30 - 40 MW zu erreichen,To achieve an output of 30 - 40 MW,

Windeinfall abgeschaltet weraen müssen. D.h., das diese Anlagen während eines Jahresdrittele keine Energie liefern.The incidence of wind must be switched off. I.e., that these systems for a third of the year do not provide energy.

Es wurde also erkannt, daß die praktische Wirkung einer Windkraftmaschine am günstigsten ist, wenn der Luftströmung nur knapp 60 Prozent ihrer Eifergie durch die rotierenden Flügel= flächen entzogen werden. Aue diesem Grund wurde hauptsächlich mit 2 oder 3 Blattrotoren Erfahrun= gen gesammelt, die aus der bestreichenden Wind= kreisflache ein entsprechend hohes, ungenutztes Windenergiepotential beziehen können. Ganz im Gegenteil zu äen langsamlaufenden Wind= turbinen. Die Leistung eines Windkraftwerkes hängt also von der Strahlfläche, d.h#, dem Quer= schnitt des rom Propeller bestrichenen Luftstrahlt vom Luftdruck und von der Windgeschwindigkeit ab. Sinnvoll wird die Erzeugung elektrischer Energie erst ab Luftgeschwindigkeiten von 3 m/s.It has thus been recognized that the practical effect of a wind power machine is most favorable is when the air flow is just under 60 percent of its zeal through the rotating blades = areas are withdrawn. Aue for this reason was mainly experienced with 2 or 3 blade rotors genes collected, the wind = circular area a correspondingly high, unused Can refer to wind energy potential. Quite the opposite of slow-moving wind = turbines. The performance of a wind power plant depends on the jet area, i.e. #, the cross = cut of the rom propeller coated air jet on the air pressure and the wind speed. The generation of electrical energy makes sense only from air speeds of 3 m / s.
