Description
Versteifung für Flugzeugrümpfe. Im Bootsbau ist es bereits bekannt, zur Versteifung der oberen, Ränder, der Bootswände wagerechte Querstäbe, trägerartige Platten o. dgl. zwischen die Wände einzufügen. Die Übertragung derartiger Querverbindungen auf die. Stellen von Flugzeugen; wo sich Motor- oder Einstiegöffnungen befinden, würde immerhin noch erheblichen Gewichtsaufwand erfordern und zudem die lichte Weite der Öffnungen in störender Weise beeinträchtigen. Gemäß @d'er Erfindung werden solche Öffnungen unter Vermeidung von Querverbindungen mit Randeinfassungen aus mehrlagigem Sperrholz versehen, deren Hauptausdehnung in einer Ebene parallel zum Rande der eingefaßten Öffnungen liegst.Reinforcement for aircraft fuselages. In boat building it is already known to stiffen the upper, edges, the boat walls horizontal cross bars, girder-like Insert plates or the like between the walls. The transmission of such cross connections on the. Placement of aircraft; where the engine or access openings are located, would still require considerable weight expenditure and also the clear width affect the openings in a disruptive manner. According to the invention, such Openings while avoiding cross connections with edging made of multilayer Plywood, the main extent of which is in a plane parallel to the edge of the lined openings.
Auf der Zeichnung ist Fig. i der Längsschnitt durch den vorderen Teil des Rumpfes, Fig. 2 die Oberansicht, Fig. 3 und q. Teilschnitte nach III-III und IV-IV .der Fig. 2.In the drawing, Fig. I is the longitudinal section through the front part of the fuselage, Fig. 2 the top view, Fig. 3 and q. Partial sections according to III-III and IV-IV. Of Fig. 2.
i ist der Rumpfboden; :2,:2 sind,die Seitenwände; 3 ist die Motorkammer, von welcher bloß der Motorträger ¢ eingezeichnet ist; 5 'und 6 sind die Kammern für Führer und Beobachter.i is the bottom of the fuselage; : 2,: 2 are the side walls; 3 is the motor chamber, of which only the engine mount ¢ is drawn; 5 'and 6 are the chambers for guides and observers.
Inder Rumpfdecke befindet sich bei 7 eine Öffnung zum- Einbringen dies Motors, bei 8 und 9 weitere Öffnungen:, die als Einstieg für Führer und Beobachter dienen. io und[ i i sind Scheidewände zum Trennen der genannten Kammern und zur Herstellung einer Querversteifung für den Rumpf.In the fuselage ceiling there is an opening for introduction at 7 this engine, at 8 and 9 more openings: that as an entry point for guides and observers to serve. io and [i i are partitions for separating the named chambers and for Manufacture of cross bracing for the fuselage.
Das Wesen der Erfindung liegt nun darin, daß die seitlichen Begrenzungen 12, und 13 für die Motor- und Beobachterkammerdecke, ferner die vordere Begrenzung 1q. der Führerkammerdecke als Träger ausgebildet sind, wobei Widerstandsfähigkeit, insbesondere gegenüber in wagerechtem Sinn wirkenden Biegungskräften, erreicht wird. Dieser Träger ist zweckmäßig aus mehrlagigem Sperrholz angefertigt, also hochkant gegenüber wagerechten Biegungskräftenangeordnet. Diese Träger sind an jenen Stellen, wo sich Querwände befinden, also beispielsweise bei den in Fig. 3 herausgezeichnetem Querschnitt, besonders kräftig durchgebildet (d. h. in der Kraftrichtung höher als zwischen zwei aufeinanderfolgenden Querwänden).The essence of the invention lies in the fact that the lateral boundaries 12 and 13 for the motor and observer chamber ceiling, and also the front boundary 1q. the driver's chamber ceiling are designed as a carrier, resistance, in particular against bending forces acting in the horizontal direction, is achieved. This carrier is expediently made of multilayer plywood, that is, it is arranged upright against horizontal bending forces. These supports are particularly strong at those points where there are transverse walls, for example in the cross-section shown in FIG. 3 (ie higher in the direction of force than between two successive transverse walls).
