ABSTRACT:
A method for scheduling the flow of cooling air to a gas turbine engine achieves a varying clearance between the turbine blade tips and surrounding annular shroud responsive to the current engine power level. Excess clearance is provided during operation at less than maximum normal engine power to accommodate the transient decrease in clearance following a step change in engine power level.
