  • Fuel and oil heat management system for a gas turbine engine
    Patent number: 4741152
    Abstract: 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.
    Type: Grant
    Filed: May 15, 1987
    Date of Patent: May 3, 1988
    Assignee: United Technologies Corporation

  • Heat exchange system
    Patent number: 4546605
    Abstract: An air/oil heat exchanger is relatively interconnected to the compressor discharge air or fan discharge air of a fan-jet engine to minimize the size of the heat exchanger core so as to be able to locate the heat exchanger within the intermediate case between struts. The plumbing may be combined with the surge bleed system to simplify the systems and reduce weight and cost.
