FIELD: engines and pumps.
SUBSTANCE: proposed jet engine consists of inlet device, driven compressor, combustion chamber, outlet device and internal air cooling system comprising cooling air feed and discharge device, intake and discharge devices. Cooling air feed and discharge device is made up of straight-flow and reverse-flow lengthwise air ducts communicated at the engine rear. Intake device communicates with straight-flow air duct and is arranged at engine inlet device. Outlet device is made up of openings communicating reverse-flow air duct with engine flow section upstream of compressor inlet.
EFFECT: higher specific thrust, cooling system and engine efficiency.
