Abstract
The invention relates to a turbomachine for an aircraft propulsion drive with a compressor, through which a gas flow streams in a flow direction of the turbomachine, a combustion chamber, a turbine, and a heat exchanger downstream of the turbine, wherein the heat exchanger is set up to produce steam from water by energy from the gas flow, which, in particular, can be fed to the gas flow for combustion with fuel in the combustion chamber.
Claims10
A turbomachine for an aircraft propulsion drive, comprising:
- a compressor, through which a gas flow streams in a flow direction of the turbomachine,
- a combustion chamber,
- a turbine, and
- a heat exchanger downstream of the turbine,
- wherein the heat exchanger is configured and arranged to produce steam from water by energy from the gas flow, which is fed to the gas flow for combustion with fuel in the combustion chamber,
- wherein the heat exchanger has at least one flow channel, through which the water flows and which has at least two sections arranged parallel to one another,
- wherein the gas flow streams at an angle through the at least two sections, which comprise different materials.
