    Abstract: A system is provided for a turbine engine that includes a fuel injector and an actuator. The system includes a fuel management system configured to receive fuel from a flow path. The fuel management system is also configured to provide a first portion of the fuel received from the flow path to the fuel injector at a first temperature, and a second portion of the fuel received from the flow path to the actuator at a second temperature different than the first temperature.

    IPC: F01D11/24

    Abstract: Flow of cooling air to a thermal clearance control system in a gas turbine engine is selectably scheduled between a normal power level versus clearance schedule 14 and an increased efficiency cruising schedule 26. Selection of the cruising schedule 26 is accompanied by a limitation on the rate of engine power increase during the period when the cruise schedule is selected. Selection and deselection of the cruising schedule 26 may be dependent upon engine speed or power demand setting, ambient air pressure or temperature, altitude, engine pressure ratio, operator input or the time since the last engine power level demand change.

    IPC: F01D11/24

    Abstract: Clearance between blade tips and an annular shroud is controlled by enhancing the thermal response of the engine case and annular shroud during the transient response period following a step change in engine power. A temporary reduction or elimination of the flow of cooling air supplied to the engine case by the active clearance control system ensures that the radius rs of the case follows curve 34 instead of curve 32 leading to an increased minimum clearance delta min. Substituting a flow of relatively warm air for the cooling air leads to a further increase in the response of the case (curve 36) and a further increase in delta min.
