High Temperature Materials: an Introduction to Onera’s Contribution


T. Khan

The third issue of Aerospace Lab is dedicated to high temperature materials.
Onera has been at the forefront of research and development for this
class of materials for the past five decades, especially for aerospace engine
applications. Starting in the mid 1960’s, many new materials and processes
were invented, and cutting-edge research was carried out during this period.
Similarly and concurrently, great progress has been made in mechanical
modeling and lifing analysis, but a description of these aspects will require
a full separate issue. The focus here is on materials in the hot sections of
compressors and turbines. These materials have a wide range of applications.
The purpose of the papers that follow is to illustrate the state-of-the art, the
progress made and the future outlook for such materials in propulsion systems.
