    Abstract: An example gas turbine engine includes a propulsor assembly including at least a fan module and a fan drive turbine module; a gas generator assembly including at least a compressor section, a combustor in fluid communication with the compressor section, and a turbine in fluid communication with the combustor; and a geared architecture driven by the fan drive turbine module for rotating a fan of the fan module. A weight of the fan module and the fan drive turbine module is less than about 40% of a total weight of a gas turbine engine.

    Abstract: A method for enhancing the thermal response of the engine case and annular shroud during the transient response period following a step change in engine power provides for the temporary reduction or elimination of the flow of cooling air supplied to the engine case by the active clearance control system. An alternate method additionally substitutes a flow of relatively warm air to further increase the response of the case.
