FIELD: engines and pumps.
SUBSTANCE: proposed engine running on detonating fuel-air mixture comprises, at least, one fire tube with crosswise lower section moving relative to said tube to occupy two extreme positions. Note here that first position corresponds to detonation phase and second position corresponds to phase of feed into said chamber. Engine comprises also outer case around fire tube making peripheral annular chamber around tube lateral wall to allow air flow from engine intake. Fixed flow guides are arranged in said peripheral annular chamber to make flow channels and, at least, one moving unit is arranged in said chamber. Said moving unit is arranged in annular chamber and connected with moving lower part to displace along fire tube lateral wall. Note here that said moving unit may shut off one of flow channels to direct portion of airflow in direction of inlet and unlock said channel when its lower part stays in first position.
EFFECT: perfected design.
