Description

Das Flugzeug wird mit einer Vorrichtung zur zeugung eines kräftigen Gärstrahls ausgerüstet. Oberhalb des Rumpfes befindet sich eine Gasleitungsröhre mit einer Düse, wobei die Röhre um ein Gelenk nach oben geschwenkt werden kann. In der Ruhelage liegt die Röhre nebst Düse in einer Aussparung im Rumpf, um bei der Fahrt keinen schädlichen Luftwiderstand zu bieten. Im Falle des Absturzes wird die Röhre nach oben geschwenkt, so daß sie über dem Schwerpunkt steht und die Düse nach Ansicht des Erfinders als eine Aufhängungsstelle in der Luft schwebt. Der regulierbare und ein- bzw. abschaltbare Gasstrahl strömt aus mehreren Düsenöffnungen schräg nach unten, so daß er den Rumpf und die Flügel frei läßt. Der Rückstoß liefert Auftrieb. Der Führer gibt den Gasstrahl nach Bedarf, besonders dicht über dem Erdboden bzw. über dem Wasser zwecks sanfter Landung.The aircraft comes with a device for generating a powerful Equipped with fermentation jet. A gas pipe is located above the fuselage with a nozzle, whereby the tube can be pivoted upwards around a hinge. In the rest position, the tube and the nozzle are located in a recess in the fuselage not to offer any harmful aerodynamic drag when driving. In the event of a crash it will the tube swung up so that it is above the center of gravity and the nozzle floats in the air as a suspension point according to the inventor. The adjustable one and the gas jet that can be switched on and off flows diagonally from several nozzle openings down so that it leaves the fuselage and wings free. The recoil provides lift. The guide gives the gas jet as required, particularly close to the ground or over the water for a gentle landing.

Der Gedanke der Benutzung des Gasstrahls kann auch in folgender Weise verwirklicht werden: Eine Düse oder mehrere Düsen schicken Gasstrahlen längs über die Decke des Rumpfes und längs "über die Flügel, damit ein kräftiger Sog entsteht. Der normale Luftdruck unterhalb des Rumpfes und der Tragflächen beträgt unter Seehöhe mehr als io t je i m2. Eine erhebliche Senkung des Luftdrucks in einer Gasströmung liefert daher eine sehr große Auftriebskraft.The idea of using the gas jet can also be in the following way can be realized: One or more nozzles send jets of gas along the length the ceiling of the fuselage and lengthways "over the wings, so that a strong suction is created. The normal air pressure below the fuselage and the wings is below sea level more than io t per i m2. A significant decrease in air pressure in a gas flow therefore provides a very large buoyancy force.

Die Benutzung von Gasströmen, und zwar ihres Rückstoßes und ihrer Saugkraft, ist daher nach Ansicht des Erfinders geeignet zum Bremsen der Geschwindigkeit eines stürzenden Flugzeugs, ferner zum Erzielen eines steilen Aufstiegs und eines steilen Abstiegs. Die große Schwere der modernen Reise- und Transportflugzeuge hat zur Folge, daß sehr lange Flugplätze nötig sind. Besonders macht die große Landungsgeschwindigkeit den Ingenieuren Sorge. Deshalb sind steilschräger Aufstieg und steilschräger Abstieg von Wichtigkeit, und zugleich wird nach Ansicht des Erfinders die Bewahrung vor einer Absturzkatastrophe erzielt.The use of gas streams, their recoil and theirs Suction force, therefore, according to the inventor, is suitable for braking the speed of a falling airplane, also for achieving a steep ascent and one steep descent. The great heaviness of modern travel and transport aircraft has the consequence that very long airfields are necessary. What makes it special is the high landing speed the engineers worry. That is why there is a steep ascent and a steep descent of importance, and at the same time, in the view of the inventor, the preservation is before a catastrophe.
