A device for the repeated production of explosions includes an explosion space, a feed conduit for feeding a flowable, explosive material, a discharge opening for the directed discharge of a gas pressure produced by the ignition of the explosive material in the explosion space, and a movable closure element for the partial or complete closure of the discharge opening. The device includes an exit nozzle with a nozzle entry area and a nozzle exit area, as well as an actuation device. The actuation device is adapted, after an opening of the discharge opening and an outflow of explosion gases through the exit nozzle, to adjust an area ratio between the nozzle entry area and the nozzle exit area. The area ratio at least approximately follows an ideal area ratio for the production of a maximal exit speed of the explosion gases, in dependence on the pressure in the explosion space. |

1. A device for the repeated production of explosions for the propulsion of an aircraft, comprising an explosion space, a feed conduit for feeding a flowable, explosive material, a discharge opening for the directed discharge of a gas pressure produced by the ignition of the explosive material in the explosion space, and a movable closure element for the partial or complete closure of the discharge opening,
wherein the device comprises an exit nozzle with a nozzle entry area and a nozzle exit area, as well as an actuation device that is designed, after an opening of the discharge opening and an outflow of explosion gases through the exit nozzle, to adjust an area ratio between the nozzle entry area and the nozzle exit area, said area ratio at least approximately following an ideal area ratio for the production of a maximal exit speed of the explosion gases, in dependence on the pressure in the explosion space. |
