The volume constraints imposed by current launch modules and the desirability of large reflectors and communication booms for space applications has given rise to active research in the field of deployable systems. These systems are stowed in a compact package for launch before being deployed into their operating configurations in orbit.
A new concept for a deployable antenna is presented. The deployment of one such 5.0 m antenna is investigated. The antenna is deployed by a number of mechanical joints. The energy stored in these joints is quantified and the deployment times and stresses at ‘latch-up’ are predicted.
