Abstract
The specific innovation proposed by MiTir in response to the US Army topic is a high performance compliant foil radial seal for advanced turboshaft/turboprop engines to replace labyrinth seals and/or brush seals. A non-contacting compliant dynamic seal overcomes the performance and life limitations associated with contacting seals in which clearances between the rotating and static structures increases with time, resulting in increased flow and decreased differential pressure across the seal. Mohawk Innovative Technology, Inc. (MiTi?) proposes continued research and development of a robust, high temperature, high speed, non-contacting, hydrodynamic compliant foil seal with a leakage rate far less than either a labyrinth or brush seal that will not degrade in performance between engine overhauls, even after rotor excursions due to maneuver loads or surge. To achieve this goal, a two pronged approach will be used that includes the application of an existing foil seal analysis capability and verification testing of a new compliant foil seal design. The objective of this Phase I effort is the resolution of design limitations identified under previous compliant foil seal testing.
