Abstract

There is provided a fuel management system (400A) for a gas turbine engine. The fuel management system comprises: a fuel tank (41) configured to store fuel for the gas turbine engine; a fuel supply line (410) configured to supply fuel from the fuel tank to a combustor (16) of the gas turbine engine; a reheat fuel supply line (412) configured to supply fuel from the fuel tank to a reheat of the gas turbine engine, the reheat fuel supply line extending from a reheat branching point (411) on the fuel supply line to the reheat; a fuel supply pump (451) disposed along the fuel supply line upstream of the reheat branching point; a reheat pump (460) disposed along the reheat fuel supply line, the reheat pump configured to pressurise fuel to a reheat delivery pressure for delivery to the reheat; and a reheat recirculation line (480) configured to recirculate fuel from the reheat fuel supply line to a location upstream of the fuel supply pump, the reheat recirculation line extending from a reheat recirculation branching point (471) on the reheat fuel supply line downstream of the reheat pump.
