The invention relates to a combustion turbine (1) in which combustion is intermittent and which comprises at least one combustion chamber (3) that has intake valves (2) and an ignition device (18). The at least one combustion chamber (3) has no blocking devices at the exhaust end and is therefore constantly open at the exhaust end. A turbine (4), to which a working gas obtained in the combustion chamber (3) can be fed, is arranged downstream of the at least one combustion chamber (3). A flow chamber (5) is arranged axially behind the at least one combustion chamber (3), between the at least one combustion chamber (3) and the turbine (4). The flow chamber (5) is delimited from the at least one combustion chamber (3) by a flow plate (6) or another turbine (7). The invention also relates to a method for operating a combustion turbine (1) as well as a drive system for a machine comprising the claimed combustion turbine (1) as the essential piece.

A compound engine assembly (10) with at least one rotary internal combustion engine (12), an impulse turbine, and an exhaust pipe (68) for each internal combustion engine (12) providing fluid communication between the exhaust port (50) of the respective internal combustion engine (12) and the flow path (60) of the turbine. Each exhaust pipe (68) terminates in a nozzle (70). For each exhaust pipe (68), a ratio Vp/Vd between the pipe volume Vp and the displacement volume Vd of the respective internal combustion engine (12) is at most 1.5. A minimum value of a cross-sectional area of each exhaust pipe (68) is defined at the nozzle (70). In one embodiment, a ratio An/Ae between the minimum cross-sectional area An and the cross-sectional area Ae of the exhaust port (50) of the respective internal combustion engine (12) is at least 0.2. A method of compounding at least one rotary engine (12) is also discussed.
