Abstract An increasing number of satellites is presently utilizing extensible and deployable large area structures after launch, while in orbit. A deployment and retracting method using an electromagnetic force for extensible panels on satellites is proposed. Using the proposed method, a satellite can retract panels to a much smaller volume to avoid damage from space debris and achieve agile attitude maneuvers. Furthermore, panels can be deployed quasi-statically using electromagnetic forces to reduce the impulsive force exerted on fragile panels in the deployment operation. Finally, numerical simulations were conducted to assess the usefulness of the proposed method using multibody dynamics (MBD). From these simulations, the satellite can deploy 10 panels in 6000s using 1A current for a small cubic satellite of 20cm dimension. Under the same conditions, the satellite can retract the 10 panels in 1400s.
Highlights We proposed a novel system for extensible structures using electromagnetic forces. Panels can be deployed quasi-statically to reduce the impulsive force. A satellite can retract panels to a much smaller volume after their deployment. MBD simulations were conducted to assess the usefulness of the proposed method.
