Abstract
A fuel management system for a gas turbine engine. The fuel management system comprises a fuel supply line configured to supply fuel from an inlet to a combustor of the gas turbine engine. The fuel management system also includes a recirculation line extending from a recirculation point on the fuel supply line and configured to recirculate excess fuel from the fuel supply line for resupply to the fuel supply line. In addition, the fuel management system comprises a heat exchanger configured to reject heat from a thermal load of the gas turbine engine to fuel in the fuel management system. The heat exchanger is disposed on the fuel supply line upstream of the recirculation point or on the recirculation line. The fuel management system further comprises a fuel cooling device disposed along the recirculation line and configured to reject heat from the excess fuel therein.
