Abstract

The wind turbine consists of a windsock (1), of a helically wound shape. The wind flows into the helical nozzles, to turn the turbine. The helical windsock may incorporate two separate channels. These channels are identical and are twisted round one another. They may taper from the front end where the wind enters towards the rear end. The windsock is mounted on a mast (2) which allows free swivelling in azimuth through 360 deg. USE/ADVANTAGE - Lightweight wind turbine gives high performance in low winds and operates with very low loading due to centrifugal force.

Description

WindturbineWind turbine

Eine Windhose, jedoch schraubenförmig.A wind pant, but helical.

Der Wind strömt in die zopfförmig gewundenen Düsen und dreht die Windturbine durch den Druck auf die Düsenleibung um die Drehachse.The wind flows into the braid-shaped ones Nozzles and turns the wind turbine by the pressure on the nozzle reveal around the axis of rotation.

Vorteile gegenüber herkömmlichen WindmühlenAdvantages over conventional windmills

Leichtes Material, auch Tuch.
Keine oder sehr geringe Zentrifugalkraft.
Kein Fliehkraftregler nötig.
Heckflosse unnötig - Windfahne.
Geringes Gesamtgewicht.
Weniger Platz bei gleicher Leistung.
Der Druck auf den Mast viel geringer.
Am Top eines Segelschiffes gefahrlos, auch wenn es mit dem Segel in Berührung kommt.
Einfache Fertigung, kein Auswuchten nötig.
Höhere Leistung und geringerer Widerstand durch die Düsenwirkung.
Auf dem Mast eines Segelschiffes ist die Windturbine Windrichtungsanzeiger und Windgenerator für die Ladung der Bordbatterie.
Geeignet als Klein- oder Großanlage.Light material, also cloth.
No or very little centrifugal force.
No centrifugal governor required.
Tail fin unnecessary - wind vane.
Low overall weight.
Less space with the same performance.
The pressure on the mast is much less.
Safe on the top of a sailing ship, even if it comes into contact with the sail.
Simple manufacture, no balancing required.
Higher performance and lower resistance due to the nozzle effect.
On the mast of a sailing ship, the wind turbine is a wind direction indicator and a wind generator for charging the on-board battery.
Suitable as a small or large system.

Oberbegriff: WindturbineGeneric term: wind turbine Kennzeichnender Teil:
Eine Windhose, schraubenförmig gewunden. Der Wind strömt in die zopfförmig gewundenen Düsen und dreht die Windturbine.Characteristic part:
A wind pants, helically wound. The wind flows into the braided nozzles and turns the wind turbine. Erfinderische Merkmale:
Durch die Düsenwirkung des gewundenen Windschlauches wird bei leichten Winden hohe Leistung erzielt.Inventive features:
Due to the nozzle effect of the winding wind hose, high performance is achieved in light winds. Oberbegriff/Merkmale:
Es treten keine oder nur sehr geringe Zentrifugalkräfte auf, da die Windkräfte um die Drehachse wirken.General term / characteristics:
No or very little centrifugal force occurs because the wind forces act around the axis of rotation. Weitere Merkmale:
Es ist keine Heckflosse nötig, da der Windsack seine Öffnung selbst stetig in den Wind hält.Other features:
There is no need for a tail fin because the windsock keeps its opening in the wind.
