Abstract
Description
Die vorliegende Erfindung betrifft ein Tragflügelverbund flugzeug mit einer deltaförmigen Bodeneffekttragfläche, die über wingletartige Fortsätze und Randbogen mit einer darüberliegenden Rechteck-Stabilisierungsfläche zu einem Tragflügelverbundsystem ergänzt ist.The present invention relates to a wing assembly aircraft with a delta-shaped floor effect wing, the over winglet-like extensions and marginal arches with a Rectangular stabilization surface above to one Wing composite system is supplemented.
Bei Fahrzeugen dieser Art gemäß Patenthauptanmeldung P 36 12 911.1 ist die Wasserstartfähigkeit dadurch ge währleistet, daß unter der Deltafläche eine trimaranähn liche Schwimmerkonfiguration vorgesehen wird, die aus einem zentralen Hauptrumpf und zwei Stützschwimmern be steht.For vehicles of this type according to the main patent application P 36 12 911.1 is the water start ability ge ensures that under the delta area a trimaran-like Liche float configuration is provided that from a central main hull and two support floats stands.
Eine solche Schwimmeranordnung erfordert einen erhebli chen Bauaufwand, erzeugt erheblichen aerodynamischen Widerstand und verringert die minimale effektive Flug höhe des Bodeneffektsystems.Such a float arrangement requires a considerable amount Chen construction effort, generates considerable aerodynamic Resistance and reduces the minimum effective flight height of the floor effect system.
Aufgabe der Erfindung ist es daher, eine hydrodynamische Lösung zu finden, die wenig Bauaufwand erfordert, geringen aerodynamischen Widerstand hat und die minimale Flughöhe nicht einschränkt.The object of the invention is therefore a hydrodynamic Finding a solution that requires little construction, little has aerodynamic drag and the minimum flight altitude not restricted.
Die Lösung dieser Aufgabe besteht darin, den Deltaflü gel zugleich als Bootsrumpf auszulegen.The solution to this problem is the Deltaflü gel also designed as a boat hull.
Um dies für das Tragflügelverbundflugzeug zu erreichen, wird die Deltafläche so gepfeilt, daß ihre Mittellinien länge mindestens 60% der Spannweite beträgt. Zusätzlich erhält sie eine leichte positive V-Stellung und ein bi konvexes Profil, dessen Unterseite einen bootstypischen Zylinderkoeffizienten für die teilgetauchte Deltafläche ergibt.To achieve this for the composite wing aircraft, the delta area is swept so that its center lines length is at least 60% of the span. In addition it gets a slightly positive V-position and a bi convex profile, the underside of which is typical of a boat Cylinder coefficients for the partially submerged delta area results.
Die Deltaflächenunterseite entspricht bei dieser Auslegung für den getauchten Teil dem Unterwasserschiff eines Gleit bootes und kann für leichteres Aufgleiten mit Stufenleisten versehen werden. Um ein klebefreies Abwassern bei fehlender, üblicher Stufe zu gewährleisten, kann die Unterseite der Deltafläche hinter dem Schwerpunkt durch Sauglenzer mit Luftführung sehr stark ventiliert werden. The underside of the delta surface corresponds to this design for the submerged part the underwater ship of a glide bootes and can with step bars for easier sliding be provided. To ensure tack-free sewage in the absence of To ensure the usual level, the bottom of the Delta area behind the center of gravity with suction arm Ventilation can be very strongly ventilated.
Der aerodynamische Widerstand des hydrodynamisch akti ven Flügelteils liegt für die gefundene Auslegung kaum über dem Widerstand, den die Deltafläche ohne Stau leisten und Ventilationsklappen zeigt.The aerodynamic resistance of the hydrodynamically active ven wing part is hardly for the interpretation found about the resistance that the delta area has without congestion perform and shows ventilation flaps.
Die minimale Flughöhe entspricht dem Wasserkontakt der Tragfläche und ist somit geringstmöglich.The minimum flight altitude corresponds to the water contact of the Wing and is therefore as small as possible.
Die Abbildung zeigt schematisch eine Beispielkonfigu ration, in der bezeichnen:The figure schematically shows an example configuration ration in which designate:
-
1 die Deltafläche
2 die Rechteckstabilisierungsfläche
3 den wingletartigen Übergang
4 die Mittellinie der Deltafläche mit bikonvexem Profil
5 die Unterseite der Deltafläche 1 the delta area
2 the rectangular stabilization area
3 the winglet-like transition
4 the center line of the delta surface with a biconvex profile
5 the underside of the delta area
Für die Deltaflächenunterseite ist dabei ein Profil zu wählen, dessen Gesamtverdrängung im teilgetauchten Zustand einen Verdrängungsschwerpunkt ergibt, der unter dem für die Flugstabilität zu liegen kommt.A profile is closed for the underside of the delta area choose its total displacement in the partially submerged state results in a center of displacement that is below that for the flight stability comes to rest.
Eine geringe Dickenrücklage gewährleistet neben nur mäßigen Entwölbungseffekten im bodennahen Flug sehr geringe Saugten denzen für die Phase des hydrodynamischen Angleitens.A small thickness reserve ensures only moderate Deflection effects in low-level flight very little suction for the phase of hydrodynamic planing.
