Device and method for affecting an object by means of pressure waves, where the pressure waves are generated by fuel being introduced to and ignited in a cylindrical combustion chamber (2), which have a closed rear end (3) and an open front end (4). A rapidly rotating vortex ring (11) is created when a pressure wave (16), generated at an ignition, forces the gas enclosed in the combustion chamber (2) out through the opening (10) of a ring-shaped flange (9), which has an internal diameter that is smaller than the inside diameter of the combustion chamber and which is arranged at the front end (4) of the combustion chamber. The vortex ring (11) moves forwards in the longitudinal direction of the combustion chamber and causes an impact on an object which is hit by it. |
