Satellite Solar Panel Deployment Mechanism

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.

Satellite solar panel deployment mechanism.

The deployment system is based on a plastic fiber wire and thermal cutters guaranteeing a suitable level of reliability. 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. To deploy the solar panels. Satellite solar panel deployment demonstrator.

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. The mechanism is designed around the concept of deploying a solid strut using counter rotating cylinders joined by a cable. Consequently the analysis on the dynamic characteristic of the deployment mechanism must be done at an initial design stage. It overcomes the performance issues caused by shrinkage which is common in the standard systems that depend on tethers to maintain alignment.

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. Satellite failure history based on presentation at 2005 space power workshop.
