Design, testing, and analytical characterization of a low-hysteresis linkage-actuated re-deployable radiator for deep space missions

Key Points

• This actuator design demonstrates reduced hysteresis, enabling more precise control during deployment and retraction phases.
• Tests revealed the radiator's performance under varying thermal conditions, further validating its reliability in space missions.
• Assessment using analytical characterization techniques highlighted the efficiency of the radiator mechanism over traditional designs.
• The findings support the potential for using this advanced radiator in future interplanetary missions, improving spacecraft thermal management.
