| description | The invention relates to locomotive gas turbine engines which run on liquefied natural gas. The gas turbine arrangement comprises three pressure shafts. A high-pressure shaft is disposed above a low-pressure shaft and a medium-pressure shaft. A low-pressure compressor with an inlet duct is mounted on the low-pressure shaft and is connected by a shaft to a low-pressure turbine and by a gas connection via a channel to a medium-pressure turbine; the medium-pressure turbine is mounted on the medium-pressure shaft and is connected by a shaft to a first synchronous traction generator and by a channel to an intermediate combustion chamber; a high-pressure compressor is mounted on the high-pressure shaft and is connected by a shaft to a high-pressure turbine and by a channel to a main combustion chamber. The low-pressure compressor is equipped with a rotating guide vane driven by the unit, a by-pass valve is mounted on an intercooler, the main combustion chambers, connected by a channel to the high-pressure turbine, are situated in a regenerative heat exchanger, the high-pressure compressor is connected via a shaft and a reduction gear to a starter, and the high-pressure turbine is connected by a shaft to a second synchronous traction generator in order to make it possible for the gas turbine arrangement to run at no load and at light loads from the high-pressure valve only. The technical result of the invention is a significant reduction in the fuel consumption of the gas turbine arrangement at no load and at light loads, and the elimination of the need for an auxiliary diesel generator on the locomotive. |
