Claims (6)

1. Mehrstufiges Staustrahltriebwerk, dadurch gekennzeichnet,
daß auf den Lufteinlaß einer Brennkammer, wie sie in Stau­ strahltriebwerken verwendet wird, ein, von einem Motor angetriebener Achsialkompressor montiert ist, dessen Leis­ tung ausreicht, um die Brennkammer in Betrieb zu setzen.
Auf die Austrittsöffnung der Brennkammer ist ein kurzes Verbindungsrohr montiert, daß mit seinem anderen Ende auf den Einlaß einer weiteren, gleich großen Brennkammer, wie sie in Staustrahltriebwerken verwendet wird, montiert ist.
Das Verbindungsrohr hat Lufteinlaßöffnungen, die so aus­ geführt und angeordnet sind, daß durch vorbeistreichende Verbrennungsgase aus Brennkammer 1, Außenluft angesaugt werden kann.1. Multi-stage ramjet, characterized in that
that on the air inlet of a combustion chamber, as is used in jam jet engines, a motor-driven axial compressor is mounted, the performance of which is sufficient to put the combustion chamber into operation.
A short connecting tube is mounted on the outlet opening of the combustion chamber, the other end of which is mounted on the inlet of a further combustion chamber of the same size as is used in ramjet engines.
The connecting pipe has air inlet openings which are guided and arranged in such a way that outside combustion air can be sucked in by combustion gases flowing past from combustion chamber 1 . 2. Mehrstufiges Staustrahltriebwerk nach Anspruch 1, dadurch gekennzeichnet, daß an die Austrittsöffnung der Brennkammer 2 ebenfalls ein kurzes Verbindungsrohr mon­ tiert ist, daß mit seinem anderen Ende auf den Einlaß einer Weiteren, gleich großen Brennkammer, wie sie für Staustrahltriebwerke verwendet wird, montiert ist. Das Verbindungsrohr hat ebenfalls Lufteinlaßöffnungen, die so ausgeführt und angeordnet sind, daß durch vorbeistrei­ chende Verbrennungsgase aus Brennkammer 2, Außenluft angesaugt werden kann.2. Multi-stage ramjet according to claim 1, characterized in that a short connecting pipe is also installed at the outlet opening of the combustion chamber 2 , that with its other end is mounted on the inlet of another combustion chamber of the same size as is used for ramjet engines . The connecting pipe also has air inlet openings, which are designed and arranged so that outside air can be sucked in by combustion gases coming from combustion chamber 2 . 3. Mehrstufiges Staustrahltriebwerk nach Anspruch 1, dadurch gekennzeichnet, daß an die Austrittsöffnung von Brennkammer 3 ebenfalls ein kurzes Verbindungsrohr mon­ tiert ist, daß mit seinem anderen Ende auf den Einlaß einer weiteren, gleich großen Brennkammer, wie sie für Staustrahltriebwerke verwendet wird, montiert ist. Das Verbindungsrohr hat ebenfalls Lufteinlaßöffnungen, die so ausgeführt und angeordnet sind, daß durch vorbeistrei­ chende Verbrennungsgase aus Brennkammer 3, Außenluft an­ gesaugt werden kann. 3. Multi-stage ramjet according to claim 1, characterized in that a short connecting pipe is also installed at the outlet opening of combustion chamber 3 , that with its other end is mounted on the inlet of another combustion chamber of the same size as is used for ramjet engines . The connecting pipe also has air inlet openings, which are designed and arranged so that outside air can be sucked in by combustion gases coming from combustion chamber 3 . 4. Mehrstufiges Staustrahltriebwerk nach Anspruch 1, dadurch gekennzeichnet, daß der Kompressor, bzw. der Motor eine Steuerung hat, die ihn automatisch abschaltet, wenn ein bestimmter Luftdruck in der Einlaßöffnung des Kompressors herrscht.4. Multi-stage ramjet according to claim 1, characterized in that the compressor, or Engine has a control that switches it off automatically, when a certain air pressure in the inlet opening of the Compressor prevails. 5. Mehrstufiges Staustrahltriebwerk nach Anspruch 1, dadurch gekennzeichnet, daß der Kompressor verstellbare Turbinenschaufeln hat, die, bei stehendem Kompressor, so verstellt werden können, daß sie anströmender Luft, mög­ lichst wenig Wiederstand entgegensetzen.5. Multi-stage ramjet according to claim 1, characterized in that the compressor is adjustable Turbine blades that, when the compressor is stopped, so can be adjusted so that the incoming air is possible oppose as little resistance as possible. 6. Mehrstufiges Staustrahltriebwerk nach Anspruch 1, dadurch gekennzeichnet, daß die, in die Lufteinlaßöffnun­ gen mündenden. Luftkanäle, mit ihren Öffnungen, in Rich­ tung der anströmenden Luft gerichtet sind.6. Multi-stage ramjet according to claim 1, characterized in that the, in the air inlet opening towards the mouth. Air ducts, with their openings, in Rich direction of the incoming air are directed.
