Abstract

Hochleistungs-Druckwellenquelle zur Erzeugung wiederholbarer Druckwellen durch Zündung eines brennbaren Fluidgemisches sowie durch Erhöhung seiner Abbrandgeschwindigkeit bis zur Detonation.High-performance pressure wave source for generating repeatable pressure waves by igniting a flammable fluid mixture and increasing it Burning rate until detonation.

Die Hochleistungs-Druckwellenquelle besitzt einen zu einem Ende hin erweiterten, eine Verbrennungskammer (3) bildenden Kanal, eine Zuführeinrichtung (4) für die Komponenten des Fluidgemisches und eine Zündeinrichtung (5) im Bereich des engen Kanalendes, eine Abführeinrichtung (12) für das Abgas im Bereich des weiten Kanalendes und eine das weite Kanalende stirnseitig abschließende Membran (14) sowie mehrere über die Kanallänge verteilte Wirbelerzeuger (6-9).

Figure 00000001
The high-performance pressure wave source has a channel which widens towards one end and forms a combustion chamber (3), a feed device (4) for the components of the fluid mixture and an ignition device (5) in the region of the narrow channel end, and a discharge device (12) for the exhaust gas in the area of the wide channel end and a membrane (14) sealing the end of the wide channel end and several vortex generators (6-9) distributed over the channel length.
