session 5
- Title
Space Structures and Materials for Extreme Environment (High-temperature and cryogenic-temperature applications including thermal insulation concepts)
- type
oral
- Description
The topics to be addressed include structures and materials for extreme environments, including both cryogenic applications and high temperature applications in space related domains. The session covers the full spectrum of material, design, manufacturing and testing. Operation of structures and mechanisms in cryogenic environment is quite challenging. This concerns the components design as well as the materials they are made of or lubricants needed for proper functioning. Tanks for storage of cryogenic propellants for launch vehicle application or long term storage of cryogenic liquids require an appropriate material selection and characterization, especially when organic composite materials are considered. Cryogenic insulation for propellant tanks and lines, especially for reusable launch vehicles exposed to aerothermal loads might require a combination with high temperature thermal protection systems. (Foam with metallic protection, vacuum insulated sandwich, stand-off thermal protection…). For the elevated temperature regime, this session includes carbon-carbon and ceramic matrix composites, ultra-high temperature ceramic matrix composites, ablative materials, ceramic tiles and insulations, together with innovative structural concepts making use of the above, for propulsion systems, launchers, hypersonic vehicles, re-entry vehicles, aero capture, power generation.
