FIELD: aircraft engine engineering. SUBSTANCE: air is separated into two streams downstream of the compressor. One of the streams is fed to the top part of the turbine through the combustion chamber. The other stream is fed to the bottom part of the turbine through the remote steam generator. The oxygen of air is burnt out in the steam generator. This allows the blades of the bottom set to be cooled with cryogenic fuel supplied to the blade side. EFFECT: enhanced reliability. 2 dwg
