This white paper considers the challenges of turbine active clearance control and proposes a unique approach in reducing the tip clearance control of a civil aircraft engine. The algorithm proposed in this paper can be incorporated in the engine Digital Engine Control Unit (DECU) so that Active Clearance Control (ACC) systems can be more accurate and cost-effective. This new approach can save millions of dollars on fuel costs for the aircraft industry, which is already reeling under debt and faces major challenges in surviving because of economic uncertainties.
