Origami-Inspired Packaging for Deployable Space Membranes
Northrop Grumman Aerospace Systems
In the quest to design bigger and better space telescopes, origami is proving to be a useful source of inspiration. The International X-ray Observatory (IXO) proposed by Northrop Grumman required a sunshield to protect it from the harsh radiation environment in space. The sunshield would have to deploy axially with the telescope from a packaged length of 0.5m to a deployed length of 18m, as well as fit within the fairing during launch.
The Kresling design solution proposed consists of a series of identical triangles and can be optimised around material properties, volume constraints and surface area requirements. Compared to conventional designs, the new solution has fewer seams where heat leakage is greatest and can be manufactured from a single flat sheet of material.
