FIELD: aircraft engines. SUBSTANCE: engine has case accommodating multistage axial-flow high-pressure compressor and combustion chambers rigidly fixed to its shaft at end of each stage uniformly over circumference and provided with injectors. Fuel feed valves embedded in shaft are brought to injectors. Combustion chambers are placed at angle of 20-45 deg. to transverse plane of engine. Half of engine case is made in the form of nozzle with conical part turning into it. Inner surface of conical part carries shaped blades arranged at 90-110 deg. to its end surface. Contour of each shaped blade gradually turns from locking surface to thrust one and then to straightening surface. Space formed by free edges of blades in conical part of case facing combustion chambers accommodates cone- shaped gas cone arranged coaxially relative to case.
