DEFINITION:
Technologies and methodologies related to design, analysis, manufacture and test of structures and mechanical systems for S/C, planetary infrastructures, habitats, launchers and reentry vehicles.
Includes metallic and non metallic structures such as advanced deployable structures (solar array, radiator, shield and antenna structures), highly
loaded structures, highly stable structures and hot structures.
It also covers the materials mechanics and processes, their physical and chemical behaviour and the interaction with the operational environment through the S/C and ground infrastructure lifecycle. Furthermore, all manufacturing processes are covered.
All devices with moving parts (e.g. actuators, hold down & release devices, pointing mechanisms, deployable booms, thrust vector control mechanisms); associated specific disciplines (such as tribology and pyrotechnics) and tools (such as mechanism and magnetic simulations) are also included.
