Abstract

Das Abschwächen einer Detonation in einem Behälter- bzw. Rohrleitungssystem durch Aufteilung der anlaufenden Detonationsfront und Zusammenführen in einem Expansionsraum (17,17',30) wird dadurch erheblich effektiver, daß die Aufteilung der Detonationsfront in eine Hauptfront und eine Nebenfront erfolgt und das die Hauptfront mit einer längeren Laufzeit in den Expansionsraum (17,17',30) geleitet wird, so daß beim Eintritt der Hauptfront in den Expansionsraum (17,17',30) dieser Verbrennungsgase der Nebenfront enthält.

Figure 00000002
The weakening of a detonation in a container or piping system by dividing the starting detonation front and merging it in an expansion space (17, 17 ', 30) becomes considerably more effective by dividing the detonation front into a main front and a side front, and that the main front with a longer running time is passed into the expansion space (17, 17 ', 30), so that when the main front enters the expansion space (17, 17', 30) this combustion gas contains the secondary front.
