Description
Strahldüse für Flugzeuge mit einer Einrichtung zur Strahlumlenkung Es sind Strahlantriebe für Flugzeuge bekannt, bei denen die Treibgase entweder nach rückwärts ausgestoßen werden können, um Vortrieb zu erzeugen, oder nach abwärts, um möglichst senkrecht starten und landen zu können. Die bekannten Einrichtungen zur Umlenkung der Treibgase sind jedoch zu kompliziert.Jet nozzle for aircraft with a device for deflecting the jet There are jet propulsion systems for aircraft known in which the propellant gases are either after can be ejected backwards to generate propulsion, or downwards, in order to be able to take off and land as vertically as possible. The well-known facilities however, they are too complicated to divert the propellant gases.
Die erfindungsgemäße Ausbildung zeichnet sich durch besondere Einfachheit aus. Sie besteht darin, daß die Strahldüse eine hohlkugelförmige Erweiterung mit einer nach abwärts gerichteten Öffnung aufweist, in die eine Hohlkugel eingepaßt ist, die um eine Querachse um 90° schwenkbar ist und auf drei Seiten parallel zur Schwenkachse Öffnungen hat. Die vierte parallel zur Schwenkachse liegende Seite der Hohlkugel ist geschlossen.The training according to the invention is characterized by particular simplicity the end. It consists in the fact that the jet nozzle has a hollow spherical extension has a downwardly directed opening into which a hollow ball is fitted is, which is pivotable about a transverse axis by 90 ° and on three sides parallel to Swivel axis has openings. The fourth side lying parallel to the pivot axis the hollow sphere is closed.
Diese vierte Seite der Hohlkugel deckt je nach der Schwenkstellung der Hohlkugel entweder die nach abwärts oder die nach rückwärts gerichtete Öffnung der hohlkugelförmigen Erweiterung ab. Die nach vorn gerichtete Öffnung der hohlkugelförmigen Erweiterung der Strahldüse, durch die die Treibgase eintreten, bleibt bei jeder Schwenkstellung der Hohlkugel offen.This fourth side of the hollow ball covers depending on the pivot position of the hollow sphere either the downward or the rearward-facing opening the hollow spherical extension. The forward opening of the hollow spherical Extension of the jet nozzle through which the propellant gases enter remains with everyone Swivel position of the hollow ball open.
Die Zeichnung gibt die erfindungsgemäße Ausbildung im Prinzip wieder. Sie zeigt die Hohlkugel in derjenigen Schwenkstellung, bei der die Treibgase nach abwärts gerichtet sind. Nach einer Rechtsschwenkung der Hohlkugel um 90° können die Treibgase geradlinig nach rückwärts hindurchtreten, während die Öffnung nach abwärts verdeckt ist.The drawing shows the training according to the invention in principle. It shows the hollow ball in the pivoting position in which the propellant gases follow are directed downwards. After turning the hollow ball to the right by 90 ° the propellant gases pass straight backwards, while the opening after is covered downwards.
Die Öffnung nach abwärts in der hohlkugelförmigen Erweiterung der Strahldüse kann aus mehreren Einzelöffnungen bestehen, in denen die Treibgase sich beschleunigen. Die innenliegenden Kanten der Einzelöffnungen sind abgerundet.The opening downwards in the hollow spherical extension of the Jet nozzle can consist of several individual openings in which the propellant gases are located accelerate. The inner edges of the individual openings are rounded.
Um die Ho'hl'kugel in die hohlkugelförmige Erweiterung der Strahldüse einlegen zu können, besteht letztere zweckmäßig aus zwei Teilen. Die schwenkbare Lagerung erfolgt mittels an die Hohlkugel angeschweißter Wellenstümpfe.Around the hollow sphere in the hollow spherical extension of the jet nozzle In order to be able to insert the latter, the latter expediently consists of two parts. The swiveling one Storage takes place by means of stub shafts welded to the hollow sphere.
Die nach abwärts gerichtete Öffnung der Strahldüse muß eine solche Lage haben, daß bei abwärts gerichtetem Strahl die Richtung des Schubes annähernd durch den Schwerpunkt des Flugzeuges geht.The downward opening of the jet nozzle must be such Have a position that when the beam is directed downwards, the direction of the thrust is approximately goes through the center of gravity of the aircraft.
