Abstract In aerospace industry, saving mass on spacecrafts always remain in large demand to save launch costs or increase the available payload mass. A case study is carried out designing a first concept of an additive manufactured flywheel reaction wheel, as it one heaviest parts wheel systems. As objective minimized, while obtaining angular momentum suitable according mission requirements and maintaining recent performances. references SeaSAT commercial are used. The work includes preliminary dimension flywheels design space by MATLAB calculations, where total 15 shapes analyzed compared. most promising afterwards via finite-element tool ANSYS defined reference flywheel. used for topology optimizations (ANSYS Topology Optimization), different boundary conditions considered. final designed obtains 16% higher energy density than withstands loads. It can be concluded that was possible less keeping expected performance.
