Topic 14 – CMC Applications in Space Transportation
CMC materials originally have been developed for thermal protection systems (TPS) in reusable spacecraft in the 1970`s and nowadays are state of the art in this challenging application area. Continuous material and process development lead to lightweight and reliable TPS structures of large dimensions and highly complex shaped geometries. Due to the combination of favourable thermal and mechanical properties with low density and high abrasion and oxidation stability, this application area could be extended to CMC structures for hot aerodynamic control surfaces like body flaps or fins.
Another important application area for fibre reinforced ceramics and carbon materials (C/C) are propulsion systems for rocket launchers, reusable spacecraft and satellites. Here the focus is on high temperature stable nozzle extensions, nozzles and combustion chambers as well as on specific components for hypersonic propulsion. Promising new developments are including also low temperature applications in turbopumps.
Beside the high temperature applications, CMC materials and ceramics in general are used for highly precise, lightweight and environmentally stable satellite structures for example in communication systems. Thereby, high specific stiffness and very low coefficient of thermal expansion and long term stability in space environments are the main advantages compared to metals or fibre reinforced polymers.
In this symposium an overview of present CMC, C/C and ceramic applications in space transportation will be given and current development activities and promising future application areas will be discussed. Thereby material, manufacturing, as well as design aspects will be in the focus.
