Description

  

  Rückstosstriebwerk für Verkehrsmittel, insbesondere Flugzeuge.    Die. bekannten Rückstosstriebwerke für  Verkehrsmittel, insbesondere Fllugzeuge, be  steben meistens aus einem einzigen, einen  Kompressor, eine Brennkammer, eine Gas  turbine sowie eine Austrittsdüse umfassenden  Düsenaggregat. Solche Rückstosstriebwerke  weisen den besten Wirkungsgrad auf, wenn  die Geschwindigkeit der aus denselben aus  strömenden Gase annähernd gleich der Fort  bewegungsgeschwindigkeit des anzutreiben  den     Verkehrsmittels    ist, mit andern Worten,  wenn die relative Geschwindigkeit zwischen  den ausströmenden Gasen und der das  Triebwerk umgebenden Luft möglichst klein  ist. Sie weisen jedoch einen schlechten Wir  kungsgrad auf, wenn diese relative Geschwin  digkeit gross ist.  



  Zweck vorliegender     Erfindung    ist die  Schaffung eines Rückstosstriebwerkes, das  einerseits eine grosse Luftmenge verarbeiten  kann und bei dem anderseits die Ausströ  mungsgeschwindigkeit verhältnismässig klein  ist. Dies wird dadurch ermöglicht, dass das    den Gegenstand vorliegender Erfindung bil  dende Rückstosstriebwerk neben einem ein  Gebläse, eine Brennkammer, einer Gasturbine  und eine Austrittsdüse aufweisenden Haupt  düsenaggregat noch ein nur eine     Brennkam-          mer    und ein Gebläse aufweisendes Neben  düsenaggregat aufweist,

   wobei das     Gebläse     des     Nebendüsenaggregates    vom Rotor des       Hauptdüsenaggregates    angetrieben     wird.     



  Mehrere     Nebendüsenaggregate    können  rings um das zentral angeordnete Haupt  düsenaggregat herum oder neben dem Haupt  düsenaggregat angeordnet sein. Ferner ist es  zweckmässig, das     Gebläse    des Nebendüsen  aggregates verstellbar, das heisst mit verstell  baren Schaufeln auszubilden.  



  Auf der     Zeichnung    sind drei Ausfüh  rungsbeispiele des     Erfindungsgegenstandes     schematisch dargestellt, und zwar zeigen:       Fig.    1 einen     Schnitt    durch     ein    zwei       Nebendüsenaggregate    aufweisendes Rück  stosstriebwerk,      Fig. 2 eine schematische Stirnansicht  eines vier um das zentral     angeordnete    Haupt  düsenaggregat herum angeordnete Neben  düsenaggregate aufweisenden Rückstosstrieb  werkes und  Fig. 3 eine schematische Stirnansicht  eines ebenfalls vier Nebendüsenaggregate  aufweisenden Rückstosstriebwerkes, bei wel  chem diese beidseitig des Hauptdüsenaggre  gates angeordnet sind.  



  Beim Ausführungsbeispiel gemäss Fig. 1  ist mit 1 das Hauptdüsenaggregat abezeichnet.  Dieses besitzt ein Axialgebläse 2, eine     Brenn-          kammer    3, eine Gasturbine 4 und eine Aus  trittsdüse 5. Beidseitig dieses Hauptdüsen  aggregates sind zwei Nebendüsenaggregate 6  und 7 vorgesehen, von denen jedes ein Ge  bläse 8 resp. 9 und eine Brennkammer 10  resp. 11 besitzt. Die Gebläse 8 und 9 werden  vom Rotor des Hauptdüsenaggregates, der  von der Gasturbine 4 angetrieben wird, mit  tels der Übertragungsorgane 12 resp. 13 an  getrieben.  



  Das Rückstosstriebwerk gemäss Fig. 2 be  sitzt ein Hauptdüsenaggregat 1, um das  herum vier Nebendüsenaggregate 2, 3, 4 und  5 angeordnet sind, deren Gebläse mittels der  Übertragungsorgane 6, 7, 8 und 9 vom Rotor  des Hauptdüsenaggregates angetrieben wer  den.  



  Das Rückstosstriebwerk gemäss Fig. 3 be  sitzt ein Hauptdüsenaggregat 1 und vier  Nebendüsenaggregate 2, 3, 4 und 5, von  denen je zwei links und rechts neben dem  Hauptdüsenaggregat 1 angeordnet sind und    deren Gebläse wiederum vom Rotor des  Hauptdüsenaggregates durch übertragungs  mittel angetrieben werden.



  Recoil engine for means of transport, in particular aircraft. The. known recoil engines for means of transport, especially airplanes, be mostly from a single, a compressor, a combustion chamber, a gas turbine and an exhaust nozzle comprehensive nozzle assembly. Such recoil engines are most efficient when the speed of the gases flowing out of them is approximately equal to the speed of movement of the means of transport to be driven, in other words when the relative speed between the gases flowing out and the air surrounding the engine is as low as possible. However, they have a poor efficiency when this relative speed is high.



  The purpose of the present invention is to create a recoil engine which, on the one hand, can process a large amount of air and, on the other hand, the outflow speed is relatively small. This is made possible by the fact that the recoil engine forming the subject of the present invention has, in addition to a main nozzle unit having a fan, a combustion chamber, a gas turbine and an outlet nozzle, also a secondary nozzle unit having only one combustion chamber and a fan,

   wherein the fan of the auxiliary nozzle assembly is driven by the rotor of the main nozzle assembly.



  Several auxiliary nozzle assemblies can be arranged around the centrally arranged main nozzle assembly or next to the main nozzle assembly. Furthermore, it is expedient for the fan of the auxiliary nozzle assembly to be adjustable, that is to say to be designed with adjustable blades.



  In the drawing, three exemplary embodiments of the subject matter of the invention are shown schematically, namely: FIG. 1 shows a section through a recoil engine having two auxiliary nozzle units, FIG. 2 shows a schematic end view of a four auxiliary nozzle units arranged around the centrally located main nozzle unit and FIG. 3 is a schematic end view of a recoil engine also having four auxiliary nozzle units, in which wel chem these are arranged on both sides of the main nozzle unit.



  In the embodiment according to FIG. 1, the main nozzle unit is denoted by 1. This has an axial fan 2, a combustion chamber 3, a gas turbine 4 and an exit nozzle 5. On both sides of this main nozzle unit, two auxiliary nozzle units 6 and 7 are provided, each of which has a Ge blower 8, respectively. 9 and a combustion chamber 10, respectively. 11 owns. The fans 8 and 9 are from the rotor of the main nozzle unit, which is driven by the gas turbine 4, with means of the transmission elements 12, respectively. 13 driven.



  The recoil engine according to Fig. 2 be seated a main nozzle unit 1, around which four auxiliary nozzle units 2, 3, 4 and 5 are arranged, the fan by means of the transmission elements 6, 7, 8 and 9 from the rotor of the main nozzle unit who are driven.



  The recoil engine according to Fig. 3 be seated a main nozzle unit 1 and four auxiliary nozzle units 2, 3, 4 and 5, two of which are arranged on the left and right of the main nozzle unit 1 and the fan in turn are driven by the rotor of the main nozzle unit through transmission medium.
