FIELD: transport.SUBSTANCE: invention relates to railway transport, particularly, to rolling stock gas turbine power plants. Besides it relates to power transfer between various shafts of gas turbine unit and between the latter and locomotive traction engines. Proposed power plant comprises three pressure shafts. High-pressure shaft is arranged above low- and medium-pressure shafts. Low-pressure compressor with inlet branch pipe is engaged with low-pressure turbine shaft and communicated via channel with medium-pressure turbine. Medium-pressure turbine is fitted on medium pressure shaft and engaged with first sync traction generator with intermediate combustion chamber. High-pressure compressor is fitted on high-pressure shaft and engaged with high-pressure turbine shaft, and communicated via channel with primary combustion chamber. Cold heat exchanger is arranged between high-pressure compressor and high-pressure turbine, provided with exhaust branch pipe and communicated via channels with low-pressure turbine and high-pressure compressor. Besides, said heat exchanger accommodates fuel heating heat exchanger. Note here that low-pressure compressor is provided with rotary intake distributor driven in idling and at low rpm solely by high-pressure shaft.EFFECT: reduced fuel consumption in idling and at low rpm.2 cl, 4 dwg |
