This research project aimed to develop additively manufactured propellant tanks using non-standard metals for use in ESPA and ESPA Grande-class satellites. The propulsion systems of Dawn Aerospace use self-pressurizing propellants, eliminating the need for helium pressurants and propellant management devices. This allows for flexible, custom tank designs without additional systems, making Dawn’s propulsion systems simpler, faster to manufacture, and more cost-effective. This flexibility enables Dawn to accommodate various customer needs. The project contributes to the objectives of the Dutch space policy in the NSO roadmap for satellite systems and aligns with ESA’s goals.
