Pulsed combusion engine

摘要

A pulsed combustion apparatus includes a conduit (40) having an outer wall (60) and an inner wall (62). The inner wall (62) has a number of apertures (164, 174, 176). An interior space (44) is separated from the outer wall (60) by the inner wall (62). An induction system is positioned to cyclicly admit charges to the interior space. An ignition system is positioned to ignite the charges. Flow directing surfaces are positioned to at least cyclicly direct cooling air through the apertures.
