ABSTRACT FUEL AND OIL HEAT MANAGEMENT SYSTEM FOR A GAS TURBINE ENGINE A heat management system is provided for a gas turbine engine (10) having first and second oil cooling loops (14, 16). The system distributes excess fuel flow from a main fuel pump (44) among a plurality of upstream locations (58, 60, 68) for managing the transfer of heat between the oil loops (14, 16) and the flowing fuel. A diverter valve (62) regulates the distribution of the bypass fuel responsive to engine heat generation, oil temperature, and/or fuel temperature. A passive fuel distribution configuration using one or more fuel flow restrictors (72, 74, 76) is also disclosed.
