Satellite Solar Panel Deployment Mechanism

A test bed for the solar panel deployment testing has been developed supporting the solar array during deployment reproducing the dynamical situation in orbit.

Satellite solar panel deployment mechanism.

Self actuated deployment mechanisms utilized the stored energy in a torsion spring to drive the solar arrays during the unfolding phase after orbital insertion. Deployed concentrators around solar panel. Satellite solar panel deployment demonstrator. Solar array structures and mechanisms deployment.

Satellite failure history based on presentation at 2005 space power workshop. The deployment system is based on a plastic fiber wire and thermal cutters guaranteeing a suitable level of reliability. The mechanism is designed around the concept of deploying a solid strut using counter rotating cylinders joined by a cable.

It overcomes the performance issues caused by shrinkage which is common in the standard systems that depend on tethers to maintain alignment. Solar array panels of a satellite must be locked at an intended position in order to perform its mission successfully as the electric power source of a satellite. Resettable solar array deployment mechanism. To deploy the solar panels.

Maven solar panel deployment duration. Consequently the analysis on the dynamic characteristic of the deployment mechanism must be done at an initial design stage. 1 an active hinge which provides the kinetic energy of deployment by two redundant torsional springs 2 a passive hinge which controls the rotational speed by means of a brushed dc motor and undergoes locking in the intended position when the solar panel deployment phase finishes. Esa has developed a deployment and locking mechanism that fits within the frame surrounding a standard solar panel.

The solar panel deployment mechanism includes two parts see fig. To deploy the solar panels completely it is necessary to design the deployment mechanism which has high precision and reliability. Kevin vipavetz vip senior systems engineer.
