Development of Seals of High-Temperature and High Effectiveness Heat Exchangers Used in Advanced Turbine Engines

Abstract

This analysis predicts that the selected extruded ceramic regenerator disk and seals can withstand the 9:1 engine compression ratio and the 2000 deg F inlet gas temperature with acceptable life and leakage while providing a minimum engine plus fuel volume. Some materials development is required for 2000 deg F operation and for cyclic operation above 2150 deg F, whereas little new technology would be required at 1800 deg F operation. A conceptual layout drawing, materials list, and development plan are included.
