Satellite Solar Panel Deployment Mechanism

Consequently the analysis on the dynamic characteristic of the deployment mechanism must be done at an initial design stage.

Satellite solar panel deployment mechanism.

Resettable solar array deployment mechanism. The computer aided design cad files and all associated content posted to this website are created uploaded managed and owned by third party users. 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. Solar array structures and mechanisms deployment.

It overcomes the performance issues caused by shrinkage which is common in the standard systems that depend on tethers to maintain alignment. In such cases the motion has to be controlled by drag braking to reduce or eliminate the shock loading at the end of the stroke. Kevin vipavetz vip senior systems engineer. The solar panel deployment mechanism includes two parts see fig.

Esa has developed a deployment and locking mechanism that fits within the frame surrounding a standard solar panel. Deployed concentrators around solar panel. To deploy the solar panels. Satellite solar panel deployment demonstrator.

Composite structures large flexible array panels solar cells and thin lightweight. Satellite failure history based on presentation at 2005 space power workshop. To deploy the solar panels completely it is necessary to design the deployment mechanism which has high precision and reliability. Self actuated deployment mechanisms utilized the stored energy in a torsion spring to drive the solar arrays during the unfolding phase after orbital insertion.

Maven solar panel deployment duration. The mechanism is designed around the concept of deploying a solid strut using counter rotating cylinders joined by a cable. The deployment system is based on a plastic fiber wire and thermal cutters guaranteeing a suitable level of reliability.
