Description

Einrichtung zur Verhinderung der Flammenerscheinungen bei Nachtflügen in den Abgassammlern oder Abgasstutzen von Flugmotoren Die Erfindung bezieht sich auf eine Einrichtung zur Verhinderung der Flammenbildung in Abgasrohren von Brennkraftmaschinen.Device to prevent the appearance of flames during night flights in the exhaust manifolds or exhaust ports of aircraft engines The invention relates to a device for preventing the formation of flames in the exhaust pipes of internal combustion engines.

Nach der Erfindung werden zur Verhinderung der Flammenerscheinungen bei Nachtflügen in die Abgassammler oder Abgasstutzen von Flugmotoren an sich bekannte, gasförmige, flüssige oder pulverförmige Stoffe mit flammenerstickender Wirkung eingeführt.According to the invention are to prevent the appearance of flames in the case of night flights in the exhaust manifold or exhaust nozzle of aircraft engines known per se, Gaseous, liquid or powdered substances with a flame-suffocating effect were introduced.

Es ist zwar an sich bekannt, durch geeignete chemische Substanzen Explosionen im Bergbau zu verhüten oder Transformatorbrände zu löschen. Ferner ist schon vorgeschlagen worden, bei Auspuffanlagen für Brennkraftmaschinen Einrichtungen zur katalytischen Reinigung der Auspuffgase vo-rzusehen, bei denen die Flammenbildung dies besonderen Charakters der Anlage wegen ohnehin vermieden wird. Auspuffanlagen dieser Art lassen sich aber für Flugmotoren nicht verwenden, schon deswegen nicht, weil zum Vortrieb des Flugzeuges der Rückstol.) der Abgase mit herangezogen werden muß. Bei der Verwendung einer Aüspuflan lagc nach dem bekannten Vorschlag würde die Abgasausnutzung für den Vortrieb nicht möglich sein.It is known per se, through suitable chemical substances Prevent mining explosions or extinguish transformer fires. Furthermore is has already been proposed in exhaust systems for internal combustion engines for the catalytic cleaning of the exhaust gases, in which the flame formation this special character of the plant is avoided anyway. Exhaust systems of this type cannot be used for aircraft engines, if only for that reason, because the recoil) of the exhaust gases are used to propel the aircraft got to. When using an Aüspuflan lagc according to the known proposal exhaust gas utilization for propulsion will not be possible.

Bei der vorliegenden Erfindung kommt es demgegenüber darauf an, bei Nachtflügen zu verhindern, daß man die Flammen sieht und damit das Flugzeug ausmachen kann.In the present invention, on the other hand, it depends on To prevent night flights from seeing the flames and thus turning off the aircraft can.

Zur Ausführung des Verfahrens wird man beispielsweise tangential an den Sammler bzw. an den Auspuffstutzen in Reihe hintereinanderliegende Zuleitungen ansetzen für das Einführen der flammenerstickenden Gase bzw. chemischen Substanzen.In order to carry out the method, one is, for example, tangential the collector or the exhaust pipe in series one behind the other supply lines begin for the introduction of the flame-suffocating gases or chemical substances.

Man kann zu diesem Zwecke beis.piMsweise einen Behälter mit Tetrachlorkohlenstoff bereitstellen und diese Flüssiglveit fein zerstäubt in den Abgassammler oder in den Abgasstutzen einführen. An Stelle von Tetrachlorkohl!enstoff kann iam auch z. B. Kohlendioxyd oder ein Pulver verwendet werden, das zum größeren Teil aus Natriumbicarbonat besteht.A container with carbon tetrachloride can be used for this purpose, for example provide and this liquid gleit finely atomized in the exhaust manifold or in insert the exhaust port. Instead of carbon tetrachloride can iam also z. B. carbon dioxide or a powder can be used, the larger Part consists of sodium bicarbonate.
