The subject of the present invention is a combustion turbine (1) for intermittent combustion with at least one combustion chamber (3) having inlet valves (2) and an ignition device (18), the at least one combustion chamber (3) having no shut-off devices on the off-gas side and being thus open on the off-gas side at all times. Downstream of the at least one combustion chamber (3), a turbine (4), which can be impinged with process gas obtained in the combustion chamber (3), is positioned, with a flow-through chamber (5) being positioned between the at least one combustion chamber (3) and the turbine (4) axially behind the at least one combustion chamber (3). The flow-through chamber (5) is separated from the at least one combustion chamber (3) by a guiding plate (6) or a further turbine (7). The subject of the present invention is furthermore a process for operation of a combustion turbine (1) and a drive system for a machine having as its core a combustion turbine (1) according to the invention.

La présente invention concerne une turbine à combustion (1) dont la combustion est discontinue, présentant au moins une chambre de combustion (3) qui présente des soupapes d'entrée (2) et un dispositif d'allumage (18), la ou les chambres combustion (3) ne disposant côté échappement d'aucun dispositif d'arrêt, et étant ainsi toujours ouverte côté échappement. En aval de la ou des chambres de combustion (3) se trouve une turbine (4) qui peut être exposée à l'action d'un gaz de travail recueilli dans la chambre de combustion (3), une chambre de circulation (5) se trouvant entre la ou les chambres de combustion (3) et la turbine (4), axialement en aval de la ou des chambres de combustion (3). La chambre de circulation (5) est séparée de la ou des chambres de combustion (3) par une plaque de flux (6) ou par une autre turbine (7). L'invention a également pour objet un procédé de fonctionnement d'une turbine à combustion (1) et un système d'entraînement destiné à une machine qui comprend ladite turbine à combustion (1) comme pièce centrale.
