Description
Die Neuerung betrifft einen Flugzeugtyp, der bei erster groben Abschätzung der Konstruktionsdaten und Größenverhältnisse bereits ausgeführter Flugzeuge, bei etwa gleichen Dimensionen, dieser flächengetragener Flugzeugtyp die doppelte Nutzlast, bei unveränderlichen bisherigen Start- und Landebahnen, erbringt.The innovation concerns an aircraft type which, based on a first rough estimate of the design data and size ratios of aircraft already built, with approximately the same dimensions, this surface-borne aircraft type delivers twice the payload, with the previous runways remaining unchanged.
Das Flugzeug ist ein allgemein bekannter technischer Gegenstand, der überwiegend als Starrflügelflugzeug je nach Verwendungszweck in Flugzeugkategorien unterteilt wird. Dabei werden vorzugsweise die Triebwerke, die Treibstofftanks und die Einziehfahrwerke in den Aufbau der Tragfläche verlegt. Die unterzubringenden Einbauten beanspruchen einen Großteil der Statik. Darüber hinaus müssen Leitungen fur Treibstoffsysteme, Hydraulik und Enteisung verlegt werden.The aircraft is a generally known technical object, which is mainly divided into aircraft categories as a fixed-wing aircraft depending on its intended use. The engines, fuel tanks and retractable landing gear are preferably installed in the structure of the wing. The installations to be accommodated take up a large part of the statics. In addition, lines for fuel systems, hydraulics and de-icing must be installed.
Der Neuerung liegt somit die Aufgabe zugrunde, ein Flugzeugtyp zu schaffen, dessen Tragflächen von keinen der genannten Einbauten und Zugänglichkeiten beansprucht wird.The innovation is therefore based on the task of creating an aircraft type whose wings are not affected by any of the aforementioned installations and access points.
Die Aufgabe wird neuerungsgemäß durch die kennzeichnenden Merkmale des Hauptanspruchs gelöst. Die Ausführungsbeispiele der Neuerung sind in den Zeichnungen dargestellt und werden in der nachfolgenden Beschreibung näher erläutert.The problem is solved according to the innovation by the characterizing features of the main claim. The embodiments of the innovation are shown in the drawings and are explained in more detail in the following description.
Dadurch, daß der Treibstofftank, den Primär- Flugzeugrümpfen zwischenliegend eingefügt, als Bauelement den Aufbau einer Tragfläche hat und so beschaffen ist, einen Auftriebszuwachs bis zum Maximalauftieb durch die Beeinflussung des mittleren Triebwerkes realisiert wird.Because the fuel tank, inserted between the primary aircraft fuselages, has the structure of a wing as a structural element and is designed in such a way that an increase in lift up to the maximum lift is achieved by influencing the middle engine.

Dadurch, daß die Tragflächen an den Primär- Flugzeugrümpfen, sowie der Tragflächenkomponente am Steuer / Frachtrampf mit Heliumgas betankt sind, ist der Aufbau vordergründig in GFK- Bauweise, integrierende Bauart, Sandwichplatten nicht nur als mittragenden Außenhaut, Quer- und Längsträger versteift, sondern gekennzeichnet als Schichtbauweise. Von der Tragflächenwurzel verjüngt bis zum Tragflächenende sind die hexagonalen Wabenzellen der Sandwichplatten diflus über ein Leitungssystem einzeln mit Heliumgas betankt, als Auftrieb entgegengesetzt zur steigenden Trägheit der Tragfläche.Because the wings on the primary fuselages and the wing components on the control surface/cargo ramp are filled with helium gas, the structure is primarily in GRP construction, an integrated design, sandwich panels not only as a load-bearing outer skin, cross and longitudinal beams stiffened, but also characterized as a layered construction. From the wing root to the wing end, the hexagonal honeycomb cells of the sandwich panels are tapered and individually filled with helium gas via a pipe system, as lift counteracting the increasing inertia of the wing.
Zur Temperatursteuerung des Heliumgases befinden sich elektrischen Heizmatten als Schichtsystem zwischen den Sandwichplatten. Die gezielte Steuerung, Helium ein quasie-ideal Gas unterliegt in seinen Zustandsgrößen (Volumen, Druck und Temperatur) der allgemeinen Gasgleichung, alle Meßpunkte in einem großen Themperaturbereich liegen auf einer Geraden, die durch thermische Veränderung geregelt wird.To control the temperature of the helium gas, electrical heating mats are placed as a layer system between the sandwich plates. The targeted control, helium is a quasi-ideal gas and its state variables (volume, pressure and temperature) are subject to the general gas equation, all measuring points in a large temperature range lie on a straight line that is controlled by thermal change.
Durch die in einem Unteranspruch angegebene Maßnahme sind vorteilhafte
Weiterbildungen und Verbesserungen möglich. Dadurch, daß alle Tragflächen, bei
Erhalt der Bauelemente, Folien etc., für die Solarenergie vorgesehen sind, kann der
Energiebedarf des Flugzeuges zusätzlich
erheblich gesenkt werden.The measure specified in a subclaim enables advantageous further developments and improvements. Because all wings are designed for solar energy while retaining the components, foils, etc., the energy requirement of the aircraft can be additionally
be significantly reduced.
Auf eine Detailzeichnung der Fahrwerke, der Wölbklappen, konventionelle Klappen, Spoiler sowie Vorflügel wurde bei dem jetzigen Stand verzichtet.A detailed drawing of the undercarriage, flaps, conventional flaps, spoilers and slats has been omitted in the current state.
