Es ist eine derartige Anordnung durch eine insbesondere zum Antrie b von Flugzeugen geeignete Brennkraftmaschinenanlage bekanntgeworden, in der eine Kolbenbrennkraftmaschine auf normale Dauerleistung ausgelegt ist und bei .darüber hinausgehendem Leistungsbedarf, z. B. beim Start und Steigen des Flugzeuges, der Mehrbedarf an Leistung von Gasturbinen aufgebracht wird.-Diese können je nach Größe des Leistungsmehrbetrages entweder nur von den Abgasen der Kolbenbrennkraftmaschine oder, nach Mischung der Abgase mit einem abgezweigten Teil vorverdichteter Verbrennungsluft und Durchleitung .dieses Gemisches durch eine Zwischenbrennkammer, von den hierin erzeugten Treibgasen gespeist werden. Die Anordnung einer die leistungsabgebenden Welle zusätzlich antreibenden Gasturbine dient hier einzig und allein dem Zweck, die absolute Leistung (Vollastleistung) um ein beträchtliches Maß zu vergrößern, ohne dabei die Kolbenbrennkraftmaschine zu überlasten und ohne auf die Wirtschaftlichkeit der-Anlage bei Betrieb mit Überlast Rücksicht zu nehmen. Demgegenüber liegt bei der Erfindung die Aufgabe vor, die in einer mit Abgasturboaufladung betriebenen Kolbenbrennkraftmaschine gegebene Leistungskapazität . im Interesse einer besseren Wärmewirtschaftlichkeit weitgehend auszunutzen. Dies wird erfindungsgemäß dadurch erreicht, daß in der mechanischen Verbindung zwischen der über eine Umgehungsleitung mit Ventil hydraulisch abschaltbaren Abgasturbine und der Motorwelle zusätzlich in bekannter Weise eine Kupplung vorgesehen ist, mit der die Zuschaltung dieser Turbine bei einem Leistungsüberschuß der das Ladegebläse frei umlaufend antreibenden Verdichterturbine bei gleichzeitigem Abschluß der Umgehungsleitung selbsttätig erfolgt. Die Kupplung selbst kann von beliebiger Bauart (Freilauf, mechanische oder hydraulische Kupplung) sein. Mit der Kombination einer frei umlaufenden Abgasturbine für den Antrieb des Ladegebläses und mindestens einer weiteren, mit jener mechanisch nicht verbundenen Abgasturbine, die sowohl hydraulisch als auch mechanisch selbsttätig abgeschaltet wird, vereinigt die Erfindung die Vorteile der selbsttätigen Regelung der bekannten frei umlaufenden Abgasturbolader mit der bestmöglichen Ausnutzung überschüssiger Turbinenleistung. Vorteilhafterweise werden die Turbinenstufen beider Turbinen unmittelbar hintereinander angeordnet, so daß sie mit geringstmöglichen Verlusten betrieben und ohne nennenswerten Mehraufwand in einem Gehäuse untergebracht werden können.It is such an arrangement by a particular drive b of aircraft suitable internal combustion engine system became known in which a Piston internal combustion engine is designed for normal continuous output and with .abber additional power requirements, e.g. B. when taking off and climbing the aircraft, the More power is required from gas turbines.-These can vary depending on the size of the excess power either only from the exhaust gases of the piston internal combustion engine or, after mixing the exhaust gases with a branched off part of pre-compressed combustion air and conduction .this mixture through an intermediate combustion chamber, of the herein generated propellant gases are fed. The arrangement of a power-delivering The gas turbine, which is additionally driving the shaft, serves the sole purpose of to increase the absolute power (full load power) by a considerable amount, without overloading the piston engine and without affecting the economy the system must be taken into account when operating with overload. In contrast is the object of the invention, which is operated with exhaust gas turbocharging Piston internal combustion engine given power capacity. for the sake of a better To exploit the heat economy to a large extent. According to the invention, this is thereby achieved achieved that in the mechanical connection between the via a bypass line with valve hydraulically shut-off exhaust gas turbine and the motor shaft in addition in a known manner a clutch is provided with which the connection of this Turbine when there is an excess of power that drives the charge fan freely Compressor turbine takes place automatically with simultaneous closure of the bypass line. The clutch itself can be of any type (freewheel, mechanical or hydraulic Coupling). With the combination of a freely rotating exhaust gas turbine for the Drive of the charge blower and at least one other, not mechanically with that one connected exhaust gas turbine, which is both hydraulically and mechanically automatic is switched off, the invention combines the advantages of automatic control the well-known freely rotating exhaust gas turbocharger with the best possible utilization excess turbine power. The turbine stages are advantageously both Turbines arranged one behind the other, so that they are as low as possible Losses operated and housed in a housing without significant additional effort can be.

In der Zeichnung sind Ausführungsbeispiele der Erfindung dargestellt. Es zeigt Fig. i eine einem frei umlaufenden Abgasturboauflader vorgeschaltete Turbine,-Fig. 2 eine einem frei umlaufenden Abgasturboauflader nachgeschaltete Turbine.Exemplary embodiments of the invention are shown in the drawing. FIG. 1 shows a turbine connected upstream of a freely rotating exhaust gas turbocharger, FIG. 2 a turbine connected downstream of a freely rotating exhaust gas turbocharger.

Die in der Zeichnung mit i bezeichnete Kurbelwelle einer Brennkraftmaschine 12 ist über Zahnräder 2 und eine ausrückbare Kupplung 3 mit der Turbine 4 verbunden. Zweckmäßigerweise im gleichen Gehäuse ist die frei umlaufende Turbine 5 angeordnet, die das Ladegebläse 6 antreibt, welches durch die Leitung 7 vorverdichtete Ladeluft zur Brennkraftmaschine 12 fördert. Deren Auspuffgase werden in der Leitung 8 gesammelt und über die Leitungen 9 und io den Turbinen 4 und/oder 5 zugeführt. Durch Einbau eines umstellbaren Steuerorgans i i können die Abgase wahlweise je nach dem Betriebszustand der Brennkraftmaschine 12 entweder durch die Turbine 5 allein oder durch die Vorschaltturbine 4 und die frei umlaufende Turbine 5 geschickt werden. Durch die Kupplung 3 wird die Welle der Turbine 4 über die Zahnräder 2 mit der Kurbelwelle i mechanisch verbunden. Die Zuschaltung und Beaufschlagung der Vorschaltturbine erfolgt dabei selbsttätig in Abhängigkeit von der Belastung der -Brennkraftmaschine, z. B. durch ein nicht dargestelltes, mit dem Füllungshebel der Brennstoffregelung zusammenwirkendes Gestänge. In Fig. 2 ist eine dem frei umlaufenden Abgasturboauflader 5, 6 nachgeschaltete Turbine 4 dargestellt. Der Abgasturboauflader führt in bekannter Weise durch die Leitung 7 der Brennkraftmaschine 12 die erforderliche Luftmenge zu. Die austretenden Abgase werden in der Leitung 8 gesammelt und durch die Leitung io der frei umlaufenden Turbine 5 zugeführt. Von hier aus können die Abgase entweder durch die Leitung 9 ins Freie entweichen, oder sie werden der nachgeschalteten Turbine 4 zugeführt, die zweckmäßigerweise in einem Gehäuse mit der frei umläufenden Turbine 5 untergebracht ist. Durch die Leitung 13 gelangen die Abgase der Turbine 4 ins Freie. Je nach Belastung der Brennkraftmaschine 12 wird durch Umlegen der Klappe 14 und Schalten der Kupplung 3 entweder die frei umlaufende Turbine 5 allein angetrieben, oder es wird bei Leistungsüberschuß an der Turbine 5 die Turbine 4 zugeschaltet, so daß die Schaufeln beider Turbinen 4, 5 von den Abgasen beaufschlagt werden. Die nachgeschaltete Turbine 4 ist in ähnlicher Weise, wie bereits oben beschrieben, über ein Zahnradgetriebe und eine mechanische Kupplung 3 mit der Motorwelle i der Brennkraftmaschine 12 verbunden.The crankshaft of an internal combustion engine denoted by i in the drawing 12 is connected to the turbine 4 via gears 2 and a disengageable clutch 3. The freely rotating turbine 5 is expediently arranged in the same housing, which drives the charge fan 6, which charge air is pre-compressed through line 7 to the internal combustion engine 12 promotes. Their exhaust gases are collected in line 8 and supplied to the turbines 4 and / or 5 via the lines 9 and io. Through installation a switchable control element i i can selectively the exhaust gases depending on the operating state the internal combustion engine 12 either by the turbine 5 alone or by the upstream turbine 4 and the freely rotating turbine 5 are sent. Through the clutch 3 is the shaft of the turbine 4 is mechanically connected to the crankshaft i via the gears 2. The connection and loading of the upstream turbine takes place automatically depending on the load on the internal combustion engine, e.g. B. by a not shown, cooperating with the filling lever of the fuel control rod. In Fig. 2, a freely rotating exhaust gas turbocharger 5, 6 is connected downstream Turbine 4 shown. The turbocharger performs in a known manner through the Line 7 of the internal combustion engine 12 to the required amount of air. The exiting Exhaust gases are collected in line 8 and circulate freely through line io Turbine 5 supplied. From here, the exhaust gases can either go through line 9 escape into the open, or they are fed to the downstream turbine 4, which are expediently housed in a housing with the freely rotating turbine 5 is. The exhaust gases from the turbine 4 pass through the line 13 into the open. Depending on the load the internal combustion engine 12 is activated by folding over the flap 14 and switching the clutch 3 either the freely rotating turbine 5 is driven alone, or it is in the event of excess power the turbine 4 is switched on at the turbine 5, so that the blades of both turbines 4, 5 are acted upon by the exhaust gases. The downstream turbine 4 is similar Way, as already described above, via a gear transmission and a mechanical one Coupling 3 is connected to the motor shaft i of the internal combustion engine 12.
