Description

Regelung der Kraftwirkungen von Strömungskräften auf Strömungsflächen. Bei verschiedenen Maschinen, wie Wind-, Wasser- und Dampfturbinen, Antriebspropellern, Segel- und Steuerflächen, werden die Strömungskräfte von Gasen und Flüssigkeiten durch Flächen aufgenommen. Die Regelung der an den Flächen angreifenden Kräfte erfolgte bisher durch Änderung der Strömungsgeschwindigkeiten, der Anstellwinkel oder der Flächenwölbungen (Verwindung oder Steilklappen).Regulation of the force effects of flow forces on flow surfaces. With various machines, such as wind, water and steam turbines, drive propellers, Sail and control surfaces are the flow forces of gases and liquids recorded by surfaces. The regulation of the forces acting on the surfaces took place so far by changing the flow velocities, the angle of attack or the Surface bulges (twisting or steep flaps).

Vorliegende Erfindung ändert die Kraftwirkungen auf Strömungsflächen durch ein neues Mittel einfachster Art, nämlich durch Störung oder hbschneiden der Stromlinien mittels Reglerflächen, die aus der Strömungsfläche heraustreten. Bei geeigneter Anordnung nimmt eine Reglerfläche, die nur 11" der angeblasenen Fläche groß ist, bereits 5o Prozent der Wirkung fort. Diese Kraftverminderung ist unter Umständen Zweck der Regelung. Ein erheblicher technischer Vorteil liegt in den kleinen Abmessungen der Reglerflächen, die noch dazu baulich recht bequem angeordnet werden können.The present invention changes the force effects on flow surfaces by a new means of the simplest type, namely by disturbing or cutting the flow lines by means of control surfaces which emerge from the flow surface. With a suitable arrangement takes a controller area only 11 "of the blown area is large, already 5o percent of the effect on. This power reduction is possibly the purpose of regulation. A significant technical advantage lies in the small dimensions of the regulator faces moreover structurally quite can be conveniently arranged.

Auf der Zeichnung sind einige Ausführungsbeispiele für eine Regelung gemäß der Erfindung dargestellt.The drawing shows some exemplary embodiments for a control system shown according to the invention.

Abb. i zeigt eine Strömungsfläche mit einen einseitig wirkenden Regler, Abb. a eine Strömungsfläche mit einem zweiseitig Wirkenden Regler.Fig. I shows a flow surface with a one-way regulator, Fig. A a flow surface with a two-way regulator.

Der Regler gemäß Abb. i besteht aus einer, dem Profil der Strömungsfläche angepaßten drehbaren Fläche, deren Teilfläche 6 unterhalb der Drehachse i größer ist als die Teilfläche 5 oberhalb der Drehachse. Die Fläche tritt unter der Wirkung der Strömungskräfte aus der Strömungsfläche heraus (punktierte Der Regler nach. Abb. a besitzt zwei innerhalb der Strömungsfläche angeordnete Flächen 8, 9, die um die Achsen i o, ii aus der Strömungsfläche heraus nach außen gedreht werden können. Die Reglerflächen werden mechanisch durch Seil- oder Stangenzüge oder hydraulisch oder elektrisch gesteuert.The regulator according to Fig. I consists of a rotatable surface which is adapted to the profile of the flow surface and whose partial surface 6 below the axis of rotation i is larger than the partial surface 5 above the axis of rotation. The surface emerges from the flow surface under the effect of the flow forces (dotted The regulator according to Fig. A has two surfaces 8, 9 arranged within the flow surface, which can be rotated outwards from the flow surface around the axes io, ii Controller surfaces are controlled mechanically by cables or rods or hydraulically or electrically.

Bei sich drehenden Flächen, z. B. von Propellern, kann die Bewegun& der Reglerflächen auch durch Fliehkraftregler erfolgen, die im Innern der Flügel liegen.With rotating surfaces, e.g. B. propellers, the movement can The regulator surfaces are also done by centrifugal regulators, which are inside the wing lie.
