AbstractAdvanced Technologies Group, (ATG)Inc. proposes to develop a self-acting outer air seal for turbine blade tip clearance control. The Compliant Outer Air Seal (COAS) is based on previous successful non-contacting seal developments at ATG. A single COAS will deliver a 3-5% decrease in SFC and a 30-50°C decrease in exhaust gas temperature.
