A Non-Contacting, Compliant Seal for Improved Turbine Engine Performance

Advanced Technologies Group, Inc, (ATG) proposes a Hybrid-Advanced-Robust- Dependable (HARD) seal that exceeds the IHPTET and VAATE program goals. The seal design proposed is for air to air applications in the turbine and compressor sections. The ATG HARD seal is a non-contacting film riding seal design that will build 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 1500F, 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. The primary objective of this effort is to develop high temperature seals for implementation in the IHPTET and VAATE program, leading to extensive military and commercial applications. A specific US Army aircraft application has been identified for phase II testing. A commercial gas turbine manufacturer has requested a quote for development of advanced seals based on phase I results.
