Abstract

Limiting leakage in aerospace turbo-machinery has been a focus of engineers ever since the advent of the turbine. An increasing number of companies are finding that fiber metal abradable seals are an efficient solution to reducing the amount of compressed gas that escapes past blade tips in axial-flow compressors and turbines. These seals maintain compartmental pressure to improve sealing effectiveness in critical compression areas. The abradable material permits the blade tip to “machine” its own channel into the case during transients and unsteady-state conditions, minimizing the flow path between the blades and the housing.
