Claim 10:
11. A method of operating a gas turbine engine, the method comprising:
heating, via at least one heat exchanger of the gas turbine engine, a fuel circuit of the gas turbine engine during a first operation, the fuel circuit fluidly coupled to a combustor of the gas turbine engine;
transporting, via the fuel circuit, an inert gas in response to a temperature of the fuel circuit satisfying a temperature threshold during a second operation after the first operation;
transporting, via the fuel circuit, hydrogen during a third operation after the second operation and a fourth operation after the third operation, the fuel circuit including a mixture of the inert gas and the hydrogen during the third operation; and
terminating, via processor circuitry, transporting the inert gas between the third operation and the fourth operation, the fuel circuit including the hydrogen during the fourth operation.
