Description
DEUTSCHE SGERMAN S
Das Hauptpatent betrifft eine zum Vergrößern des Impulses eines Mediumstromes dienende Vorrichtung, die sich insbesondere als Hub- oder Antriebsvorrichtung von Luftfahrzeugen eignet und durch die Kombination eines das Medium in Geschwindigkeit versetzenden konvergierenden Rohres und eines divergierenden Teiles gekennzeichnet ist, welcher dazu dient, die Geschwindigkeit des Mediums zu dämpfen, und welcher von einem Mediumschleier gebildet wird, der durch die Abgabe eines unter Druck stehenden Mediums aus einer düsenartigen öffnung in Form eines an dem festen konvergierenden Rohr vorgesehenen und in zweckentsprechender Weise gerichteten Schlitzes erzeugt wird.The main patent relates to a device used to increase the momentum of a medium flow, which is particularly suitable as a lifting or drive device for aircraft and due to the combination one converging tube that sets the medium in velocity and one diverging tube Part is marked, which serves to dampen the speed of the medium, and which is formed by a veil of medium produced by the discharge of a pressurized Medium from a nozzle-like opening in the form of one provided on the fixed converging tube and appropriately directed slit is generated.
Zweck der Erfindung sind Verbesserungen der Vorrichtung gemäß dem Hauptpatent, um insbesondere deren Anwendung bequemer, praktischer und wirksamer zu machen.The purpose of the invention are improvements to the device according to the main patent, in particular make their use more convenient, practical and effective.
Gemäß der Erfindung ist in einem bestimmten Abstand von dem konvergierenden Teil ein fester divergierender Teil angeordnet, welcher den divergent verlaufenden Mediumschleier umhüllt und abstützt, der in diesem Abstand einen großen Teil seiner Energie und infolgedessen seiner Wirksamkeit verloren hat, wobei der feste divergierende Teil an seinem Eingang einen Querschnitt besitzt, der demjenigen des Mediumschleiers zweckentsprechend angepaßt und größer als der Querschnitt an der engsten Stelle des konvergierenden Teiles ist, von dem er durch einen Zwischenraum getrennt ist, in welchem der Mediumschleier allein wirksam ist.According to the invention, at a certain distance from the converging part there is a fixed diverging one Part arranged, which envelops and supports the divergent veil of medium, the has lost a large part of its energy and, as a result, its effectiveness at this distance, the fixed diverging part at its entrance having a cross-section corresponding to that of the medium veil appropriately adapted and larger than the cross section at the narrowest point of the converging Part is from which it is separated by a space in which the medium veil alone is effective.
DieErfindung wird nachstehend an Hand der Zeichnung an zwei verschiedenen Ausführungsformen beispielsweise näher erläutert.The invention is illustrated below with reference to the drawing in two different embodiments, for example explained in more detail.
Fig. 1 ist ein axialer Schnitt durch einen Impulsvergrößerer, der mit einem festen divergierenden Teil kombiniert ist;Fig. 1 is an axial section through a pulse enlarger provided with a fixed diverging part is combined;
Fig. 2 veranschaulicht eine Ausführungsform, die in dem Fall anwendbar ist, wo der divergent verlaufende Mediumschleier von einer Flüssigkeit gebildet wird.Fig. 2 illustrates an embodiment applicable in the case where the divergent Medium veil is formed by a liquid.
In Fig. 1 ist mit 1 der konvergierende Teil einer Hubvorrichtung bezeichnet, der an der engsten Stelle 2 oder etwas hinter dieser Stelle endet. Mit 3 ist eine düsenartige öffnung in Form eines ringförmigen Schlitzes bezeichnet, der zur Erzeugung eines von einem gasförmigen Medium gebildeten divergierenden Teiles dient, welcher sich an den festen konvergierenden Teil 1 anschließt. Mit 4 ist ein ringförmiger Sammelraum bezeichnet, der mit einem unter Druck stehenden Medium aus einer zweckentsprechenden Quelle gespeist wird.In Fig. 1, 1 denotes the converging part of a lifting device, which ends at the narrowest point 2 or a little behind this point. A nozzle-like opening in the form of an annular slot is designated by 3 , which is used to generate a diverging part formed by a gaseous medium and adjoining the fixed converging part 1. With 4 an annular collecting space is designated, which is fed with a pressurized medium from an appropriate source.
Auf den konvergierenden Teil 1 mit seiner düsenartigen öffnung 3 folgt in einem bestimmten Abstand Vorrichtung zum Vergrößern des Impulses eines Mediumstromes The converging part 1 with its nozzle-like opening 3 is followed by a device for increasing the momentum of a medium flow at a certain distance

ein gewöhnlich ziemlich kurzes divergierendes Rohr 5, welches mit dem konvergierenden Teil 1 durch Arme 6 und 6' verbunden ist. Dieses Rohr 5 kann einen kleinen konvergierenden Anfangsteil 7 aufweisen.a usually rather short diverging tube 5 connected to the converging part 1 by arms 6 and 6 ' . This tube 5 can have a small converging initial part 7 .
Es ist bei diesem Beispiel angenommen, daß der Fluß in dem konvergierenden Teil 1 durch die Wirkung des aus dem Schlitz 3 austretenden Mediumschleiers induziert wird. Das divergierende Rohr 5 ist dazu bestimmt, den induzierten Fluß durch den konvergierenden Teil 1 und den aus dem Schlitz 3 austretenden, divergent verlaufenden Mediumschleier zu führen, wenn dieser Mediumschleier nach einem bestimmten wirksamen Weg in der Luft, der durch die Pfeile F1 F' angedeutet ist, den größten Teil seiner Energie und demzufolge seiner Wirksamkeit verloren hat. Danach übernimmt das Rohr 5 gewissermaßen die Aufgabe des Mediumschleiers und verbessert die Übergangsstelle des Druckes zwischen dem induzierten Strahl und der Atmosphäre. Diese Regulierung des induzierten Flusses ist überdies von einer Erhöhung der Abgabemenge dieses Flusses begleitet, mit der eine Erhöhung des erzeugten Schubes einhergeht. Das Rohr 5 sodl sich an den Medi um sch led er anschließen, und da die starke Divergenz des Mediuraschleiers gegeben ist (der halbe Winkel an der Spitze des ge-It is assumed in this example that the flow in the converging part 1 is induced by the action of the medium veil emerging from the slot 3. The diverging tube 5 is intended to guide the induced flow through the converging part 1 and the divergent veil of medium emerging from the slot 3 when this veil of medium follows a certain effective path in the air, which is indicated by the arrows F 1 F ' is indicated, has lost most of its energy and consequently its effectiveness. Thereafter, the pipe 5 takes on the task of the medium veil and improves the transition point of the pressure between the induced jet and the atmosphere. This regulation of the induced flow is moreover accompanied by an increase in the amount of discharge of this flow, which is accompanied by an increase in the generated thrust. The tube 5 is connected to the mediureal loop, and since the strong divergence of the mediura veil is given (half the angle at the tip of the
