Refractories and Industrial Ceramics Aims and scope

Abstract

The development of rotor seals for gas-turbine engines is reported using Si3N4 – BN-based composite materials molded by hot-pressing technology. The mechanical and thermophysical properties of the newly-developed materials are determined and compared with results of a thermal stress analysis by numerical simulation method. Potential use of rotor seals of different design, in particular, multilayer components, for practical applications is discussed.
