Abstract
High-power pressure wave source for generating pressure waves that can be repeated by igniting a combustible fluid mixture and by increasing its rate of combustion up to detonation. The high-performance pressure wave source has a channel, which expands toward one of its ends and forms a combustion chamber, a feed means for the components of the fluid mixture, and an igniting means in the area of the narrow end of the channel, a discharge means for the waste gas in the area of the wide end of the channel, and a membrane closing the wide end of the channel on the front side, as well as a plurality of vortex generators distributed over the length of the channel.
