Description

Die Erfindung betrifft einen Düsenantrieb gemäß dem Oberbegriff des Patent­ anspruchs.The invention relates to a nozzle drive according to the preamble of the patent demanding

Es ist beispielsweise aus der DE-AS 12 09 808 ein Gasturbinenstrahltrieb­ werk bekannt, das die Merkmale des Oberbegriffs des Patentanspruchs auf­ weist. Die Abgasdüse verjüngt sich bei diesem bekannten Triebwerk in Strö­ mungsrichtung konisch.It is, for example from DE-AS 12 09 808, a gas turbine jet engine known work, the features of the preamble of claim points. The exhaust nozzle tapers in this known engine in Strö direction of conical.

Der Erfindung liegt demgegenüber die Aufgabe zugrunde, die Wirksamkeit des Düsenantriebes zu verbessern. Dies geschieht dadurch, daß gemäß dem Kennzeichen des Patentanspruchs die Abgasdüse als Diffusor-Schubdüse ausge­ bildet ist.The invention is based on the object, the effectiveness of To improve the nozzle drive. This happens because according to the Characteristics of the patent claim the exhaust nozzle as a diffuser-thruster forms is.

In Fig. 1 ist ein Ausführungsbeispiel des patentgemäß gestalteten Düsen­ antriebs dargestellt. Der Düsenantrieb weist ein aus Verdichter 1, Brenn­ kammer 2 und Turbine 3 bestehendes Antriebsaggregat auf, an das sich zur Schuberzeugung ein erster Beschleunigungsrohrabschnitt 4, ein Schubrohr 5, ein zweiter Beschleunigungsrohrabschnitt 6 und eine Diffusor-Schubdüse 7 anschließt.In Fig. 1 an embodiment of the patented nozzle drive is shown. The nozzle drive has a compressor 1 , combustion chamber 2 and turbine 3 existing drive unit, to which a first acceleration pipe section 4 , a push pipe 5 , a second acceleration pipe section 6 and a diffuser push nozzle 7 are connected to generate thrust.

In Fig. 2 ist ein weiteres Ausführungsbeispiel dargestellt, das sich von dem nach Fig. 1 dadurch unterscheidet, daß zwischen Schubrohr 5 und dem zweiten Beschleunigungsrohrabschnitt 6 eine weitere Brennkammer 8 ange­ ordnet ist.In Fig. 2, another embodiment is shown, which differs from that of FIG. 1 in that between the push tube 5 and the second acceleration tube section 6, a further combustion chamber 8 is arranged.
