Patent attributes
A fuel management system includes: a fuel tank; a fuel supply line that supply fuel from the fuel tank to a combustor of the gas turbine engine; a reheat fuel supply line that supply fuel from fuel tank to a reheat of the gas turbine engine, the reheat fuel supply line extending from a reheat branching point on the fuel supply line to the reheat; a fuel supply pump disposed along fuel supply line upstream of the reheat branching point; a reheat pump disposed along reheat fuel supply line, the reheat pump that pressurise fuel to a reheat delivery pressure for delivery to the reheat; and a reheat recirculation line that recirculate fuel from the reheat fuel supply line to a location upstream of fuel supply pump, the reheat recirculation line extending from a reheat recirculation branching point on the reheat fuel supply line downstream of the reheat pump.
