Abstract: A rotary internal combustion engine with intermittent burning cycle, converting heat energy into the rotary motion, with a multi stage compression rotor (3) and centrifugally-axial air compression impellers (3.2), an air valve (5.1), which alternatively filling up the combustors (4.3) with the compressed air and closing them. A fuel pump (6) compresses fuel and through fuel distributor (6.1) supplies it to the combustors (4.3) to achieve combustion when sprinkled on the hot-red spirals of the ignition plugs (4.5). The gas generated in the combustors (4.3) passes through the cascade turbines (5.10; 5.3; 5.11), driving the power rotor (5) and through the coupling-gear (5.4) transferring rotary motion to a drive shaft (7). A hollow impeller (3.5), mounted onto the compression rotor (3), pumps air through a diffusor-shade (3.8) for cooling the compressor from the outside and the inside.
