Topology Optimisation of Tertiary Structures and Mass Savings for Satellite Structures

For typical satellites, tertiary structure, i.e. supports for antennas, sensors and connectors, can represent up to 20-30kg. The introduction of new manufacturing processes like Additive Manufacturing combined with the topology optimisation capabilities of Optistruct allow to envisage mass savings of around 30%. The presentation shows the results of a topology optimisation performed by RUAG Space on an Antenna Support of the Sentinel-1 Spacecraft. It also shows how RUAG Space intend to implement this methodology combined with Additive Manufacturing in the development of future satellite structures.
