Abstract:

This SBIR development effort concentrates on blade tip clearance management in the high pressure turbine. Improved seals in this location of a gas-turbine engine provide the highest benefits to overall engine efficiency, service life, stability and stall margin. The COAS proposed will deliver a 3-5% decrease in SFC and a 30-50XC decrease in exhaust gas temperature. The ATG COAS is a non-contacting, compliant, film-riding seal design that builds on patented hybrid-Brush seal success at ATG. This vanguard design, when combined with advanced high temperature materials will provide unrivaled durability, reliability, performance, and maintainability at temperatures exceeding 2000,aF, differential pressures to 250 psi, and surface speeds of 1500 feet per second. These performance goals require innovative designs that far exceed current seal capabilities.
