Advanced Compressor Seal for Turbine Engines.

Abstract

This report describes a resilient seal concept entitled the J-Seal. This concept uses a pressure loaded membrane and hydrostatic bearing principles to maintain a minimum rotor stator clearance over a range of axial rotor displacement. Methods of analyzing this concept have been developed. A design study is presented and hardware has been fabricated. Manufacturing inadequacies in a key component caused proof of concept testing to be inconclusive, but an adequate test rig for high-temperature testing has been constructed. (Author)
