Wednesday, November 13, 2024

ONERA, Palaiseau

Day organized by Anne Denquin,

ONERA's Materials and Structures Department

PRACTICAL INFORMATION

The day is open to all auditors. There is no registration fee. Due to limited space in the conference room and in distance learning, we ask you to register as soon as possible. Registration is on a first-come, first-served basis. In face-to-face sessions, participants will be able to have lunch on site. Lunch will be at the participant's expense (20€).

For distance learning, a link will be sent to you once you have registered.

Face-to-face is preferred.

OBJECTIVES

Economic, societal and sovereignty issues in the aerospace sector have recently led to a redistribution of priorities, resulting in new needs in the field of high-performance materials and coatings. The combined need for performance and weight reduction is driving the research and development of new materials and architectures capable of operating in an ever higher temperature range. This day of exchanges between industrial, academic and institutional stakeholders in the aerospace sector will focus on current developments, research and innovations in the field of materials operating at temperatures typically between 800°C and 2500°C. Specifications for civil and military applications will be reviewed, as will those for civil space applications. Metallic solutions will then be discussed, based on the ongoing development of "conventional" materials and systems. We will also look at breakthrough solutions in metallic materials, such as intermetallic alloys and high-entropy refractory alloys. The potential of ceramics and ceramic-matrix composites, as well as recent developments in this field, will provide an alternative approach to the use of materials applicable at very high operating temperatures, not forgetting ways of limiting the effect of temperatures and the environment encountered by structural materials in general, such as thermal and environmental barriers.

This scientific and technical day organized by the joint 3AF/SF2M "Materials for Aeronautics" committee will conclude with an update on the state of the art in the field. A dozen presentations from the ASD sector will fuel exchanges and discussions. A round-table discussion will conclude the day (summary, open questions, lessons learned).
