Abstract
An aircraft propulsion system includes a gas turbine engine configured to burn hydrogen fuel supplied from a cooled hydrogen supply via a fuel conduit. A fuel offtake is configured and arranged to divert a portion of hydrogen fuel from the fuel conduit. A burner is configured to burn the portion of hydrogen fuel diverted from the main fuel conduit with air bled from the core compressor via an offtake to produce exhaust gases. A heat exchanger is configured to transfer heat from the exhaust gasses produced by the burner to hydrogen fuel in the main fuel conduit.
