In an aircraft engine with a fan or propeller drive, in which at least two shafts (1, 2) disposed to rotate coaxially and independently of one another respectively support a separate compressor (3, 4) and a separate turbine (5, 6), wherein a suitable device for combusting the gases is disposed between the compressor (4) disposed last in the flow direction and the first turbine (6), this device for combusting the gases comprises a dynamic pressure machine (9) known per se that operates with isochoric combustion and has a cellular wheel that rotates between respectively a side part on the air side and a side part on the gas side, both provided with input and output openings, and has a number of cells in which a continuously repeating ignition and combustion process takes place. In addition, a high-pressure turbine (10) is disposed behind the dynamic pressure machine (9) on the same shaft (2) as the following medium-pressure turbine (6).
