Description

Steilaufsteig- und -landefähiges Flugzeug -reit spreizbaren, senkrechten Stand ermöglichenden Gliedern am Rumpfheck Es ist bekannt, Flugzeuge an Stelle der üblichen Nurvortriebsschrauben mit Schrauben großen Durchmessers auszurüsten, um ihnen dadurch einen lotrechten Start zu ermöglichen. Es ist ferner vorgeschlagen worden, solche Flugzeuge mit spreizbaren, einen lotrechten Start ermöglichenden Gliedern auszurüsten. An dieser Anordnung ist nachteilig, daß die Spreizbeine u. dgl. ein beträchtliches Zusatzgewicht erfordern und den Gesamtwiderstand erhöhen. Es ist Aufgabe der Erfindung, diesen Maligel zu beseitigen.Aircraft capable of steep ascending and landing, spreadable, vertical Stand enabling members on the fuselage tail It is known to replace the aircraft to equip the usual propulsion screws with large-diameter screws in order to to enable them to get off to a perpendicular start. It is also suggested have been, such aircraft with expandable, a vertical takeoff enabling To equip limbs. The disadvantage of this arrangement is that the splay legs u. Like. Require a considerable additional weight and increase the overall resistance. The object of the invention is to eliminate this maligment.

Nach der Erfindung -wird das Rumpfheck aus mehreren, z. B. vier, auseinanderklappbaren Teilschalen ausgeführt, welche an dem druck- und biegesteifen vorderen Rumpfteil angelenkt sind, der den Motor mit Getriebe und, insbesondere bei kleineren Maschinen, den Besatzungsraum umfaßt. _ Diese Teilschalen können vor der Landung in ähnlicher Weise, wie es für Einziehfahrgestelle bekannt ist, vom Besatzungsraume aus mechanisch oder durch Drucköl, Hilfsmotoren usw. ausgefahren werden, so daß ein weit ausgebreitetes, vierteiliges Landegestell entsteht, welches konstruktiv leicht derart ausgebildet werden kann, daß Federungskräfte erreicht -werden, welche die Aufnahme auch großer Bodenkräfte gestatten. Im Stande ruht dann die gegebenenfalls noch mit einem eigenen Landepuffer ausgerüstete Rumpfgondel mit ihrem Heck am Boden, so daß der Schwerpunkt genügend tief liegt, bei kleineren Flugzeugen etwa z m über dem Boden, entsprechend einem zulässigen Kippwinkel von gut -o-. Die vier Teilschalen werden mit Vorrichtungen zur Aufnahme von Landestößen versehen: sie können mit ausschwenkbaren Füßen ausgerüstet sein, -welche zudem Rollkugeln oder Schwenkräder traben, um Quer-oder Längsbewegungen des nicht rein lotrecht landenden Flugzeuges ausrollen zu können.According to the invention, the rear fuselage will consist of several, e.g. B. four, unfoldable Part shells executed, which on the pressure and flexurally rigid front body part are articulated, which the engine with gear and, especially with smaller machines, includes the crew space. _ These sub-shells can be similar before landing Way, as it is known for retractable undercarriages, mechanically from the crew quarters or be extended by pressure oil, auxiliary motors, etc., so that a widespread, four-part landing gear is created, which is easily constructed in this way can be achieved that suspension forces are reached, which the recording also greater Allow ground forces. If necessary, the stand then still rests with one of its own Landing buffer equipped fuselage nacelle with its stern on the ground, so that the center of gravity is sufficiently low, in the case of smaller aircraft about z m above the ground, accordingly a permissible tilt angle of good -o-. The four sub-shells are made with fixtures to absorb landing bumps: they can be equipped with swiveling feet be, -which also trot roller balls or swivel wheels to transverse or longitudinal movements to be able to roll out of the aircraft that is not landing in a purely perpendicular manner.

In der Abbildung ist eine schematische Ausführung des Erfindungsgedankens dargestellt, und zwar in der linken Hälfte am Stand, in der rechten Hälfte im Flus. Die Rumpfgondel i trägt an ihrem vorderen Teil gegenläufige Schrauben großen Durchmessers a mit Motor und Getriebe 3 sowie die Tragdecks .l. Am Heck der Gondel sind die Teilschalen 5 angelenkt. aus welchen Federbeine 6 mit Schwenkrädern; vor der Landtung ausgeschwenkt werden: die Gondel ist zudem durch einen eigenen Landepuffer S geschützt.In the figure is a schematic implementation of the inventive concept shown, in the left half at the stand, in the right half in the river. The fuselage nacelle i has large diameter screws running in opposite directions on its front part a with engine and gearbox 3 as well as the supporting decks .l. The partial shells are at the stern of the gondola 5 hinged. from which struts 6 with swivel wheels; swiveled out before landing be: the gondola is also protected by its own landing buffer S.
