Satellite Solar Panel Deployment

Satellite solar panel deployment.

Unlike any discernible solar panel deployment mechanism with a flight history spacex s starlink engineers seem to have taken a style of deployment used successfully on the international space. 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 array measures 18 8 feet long and 9 2 feet wide and it consists of four solar panels. Each panel contains between 800 and 1 200 solar cells.

The solar panel deployment mechanism includes two parts see fig. This paper presents an innovative method to control the rotational speed of a satellite solar panel during its deployment phase. This article presents the modeling simulation and assessment of deployment and locking operations of satellite flexible solar panel using ansys and adams software. A brushed dc motor has been utilized in the passive spring driven deployment mechanism to reduce the deployment speed.

To deploy the solar panels. A test bed for the solar panel deployment testing has been developed supporting the solar array during deployment reproducing the dynamical situation in orbit. Excess power charges the satellite s battery which is used when the gpm core isn t in direct sunlight. 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.
