Description
Die Erfindung betrifft eine strömungsmechanisch wirksame Fläche eines sich in einem Fluid bewegenden Geräts, insbesondere eines Fluggeräts, insbesondere eine Tragfläche eines Fluggeräts, wobei die Fläche einen proximal zum Gerät liegenden Innenflügel und einen distal angeordneten Außenflügel umfasst, wie im Oberbegriff des Anspruchs 1 vorausgesetzt.The The invention relates to a fluid mechanics effective area a device moving in a fluid, in particular an aircraft, in particular a wing of an aircraft, being the area one proximal to the device lying inner wing and comprises a distally arranged outer wing, as in the preamble of claim 1 provided.
Bei einem sich in einem Fluid bewegenden Gerät ergibt sich bei der Bewegung durch das Fluid, also etwa bei einem Fluggerät beim Flug, eine Belastung der Fläche, welche in Spannweitenrichtung variiert und im Reiseflug (1-g-Flugzustand) von Geschwindigkeit und Höhe und vom Beladungszustand abhängt. Beim Verlassen dieser stationären Reiseflugbedingung durch Fliegen eines Manövers oder beim Auftreten von Böen oder Turbulenzen treten an der Fläche zusätzliche Lasten auf, welche bei der Auslegung der Fläche wie auch des gesamten Geräts zu berücksichtigen ist. Im Falle einer starren Tragfläche muss diese daher so ausgelegt sein, dass sie den zu erwartenden Manöver- und Böenlasten entspricht, was für die Reiseflugbedingung eine Überdimensionierung bedeutet.at a device moving in a fluid results from the movement due to the fluid, for example in the case of an aircraft during flight, a load the area, which varies in the span direction and in cruise (1 g flight condition) from Speed and altitude and depends on the loading condition. When leaving this stationary Cruising condition due to flying a maneuver or when Gusts or Turbulence occurs on the surface additional Loads, which must be taken into account when designing the surface as well as the entire device is. In the case of a rigid wing, this must therefore be designed be that it corresponds to the expected maneuver and gust loads, what the cruise condition an oversizing means.
Zur Lastabminderung von Tragflächen eines Flugzeugs ist es beispielsweise bekannt Querruder im äußeren Flügelbereich an der Hinterkante einzusetzen, wobei durch deren geringe aeroelastische Wirksamkeit im Reiseflug der Lastabminderungseffekt gering ist. Um deren Wirksamkeit zu erhöhen, müsste die Struktursteifigkeit und damit das Gewicht erheblich vergrößert werden.to Load reduction of wings An aircraft is known, for example, ailerons in the outer wing area to be used on the rear edge, due to their low aeroelastic effectiveness the load reduction effect is low in cruise. For their effectiveness to increase the Structural rigidity and thus the weight can be increased significantly.
Die Aufgabe der Erfindung ist es eine strömungsmechanisch wirksame Fläche der genannten Art zu schaffen, welche zu einer Lastabminderung von Manöverlasten oder Böenlasten in der Lage ist.The The object of the invention is a fluid mechanically effective surface to create the type mentioned, which leads to a load reduction of maneuver loads or gust loads be able to.
