Space Technology

air-guided deployment system
for satellite´s solar panels
Air-magnetic slip system
When transporting solar panels for satellites in a launching rocket, these must be folded. After reaching the orbit, they unfold via a spring mechanism weightless and frictionless. This process requires prior testing on earth due to security reasons. As for AeroLas’s testing design, the solar panels are hanged up to magnetic preloaded air-bearings when compensating the gravity. In doing so, the unfold movement process is carried out with a minimum friction impact which means that the solar panels are tested close to reality. Moreover, the design offers an absolutely maintenance-free handling with ever-equal movements.

The air-bearing components (diameter 34 mm) with integrated magnets are so small such that they are able to glide contact-less along conventional rolled sheet plates smoothly and with a bearing gap height of about 25 µm. The holding force of an air bearing for one solar panel averages 600 N. This force is achieved by an equal distribution of the load, similar to a mobile, on 16 single air bearing elements. The unfolding process of the solar panels has been developed for an area of 21 m x 2.5 m.

The permanently magnetic preloaded air-guided guidance system may be used for all kind of hanging transportation movements as well as for many other applications, such as for instance for the stick-slip-free positioning of components during an assembly.
