Abstract

A fuel system for a gas turbine engine (103) configured to combust hydrogen fuel. The fuel system comprises a main fuel conduit (226), a fuel pump (224) configured to operate on hydrogen within the fuel conduit (224) to provide pressurised fuel to a core combustor (236) of the gas turbine engine (103), an auxiliary combustor (228) downstream in fuel flow of the fuel pump (224), and configured to combust a portion of fuel diverted from the main fuel conduit (224) and to heat a remainder of fuel in the main fuel conduit (224), and a fuel turbine (234) downstream in fuel flow of the auxiliary combustor (228). The fuel turbine (234) is configured to be driven by the heated fuel from the auxiliary combustor (228) and configured to power the fuel pump (224). The fuel system comprises a turbine inlet valve (247) provided upstream in hydrogen fuel flow of the fuel turbine (234) and configured to control mass flow rate and I or pressure of fuel flowing into the fue turbine (234).I. A method of operation is also described.
