FIELD: engines.
SUBSTANCE: turbine engine with a free turbine comprises a gas generator, which includes at least one compressor fed by air, a combustion chamber which receives compressed air from outlet of said compressor, and at least one generator turbine which is mechanically connected with said compressor by means of a drive shaft and driven by gases, resulting from fuel combustion in combustion chamber. Gas outlet is directed towards compressor. Turbine engine also includes a free turbine fed by gases from combustion after their passage through generator turbine, which drives output shaft, not located in continuation of drive shaft of gas generator and transmits power from turbine engine via reduction gear. Generator turbine is an axial turbine. Combustion chamber has a substantially cylindrical shape or a truncated cone shape, located in continuation of axis of generator turbine and comprises a single injector.
EFFECT: invention is aimed at reducing manufacturing costs and reducing emissions of NOx.
