Deployable Configuration Design and Analysis of Large Space Membrane Sunshield Structures

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Review of Large Spacecraft Deployable Membrane Antenna Structures

The demand for large antennas in future space missions has increasingly stimulated the development of deployable membrane antenna structures owing to their light weight and small stowage volume. However, there is little literature providing a comprehensive review and comparison of different membrane antenna structures. Space-borne membrane antenna structures are mainly classified as either para...

Ultra-lightweight Deployable Space Structures

The ultra-lightweight construction of large, deployable space structures is a fundamental prerequisite for the realization of Solar Sail propulsion concepts. In addition to the functionality of the deployment technique and the development of control concepts, lightweight aspects and their technical implementation play a key role in future Solar Sail missions. A further development of the set-up...

Combining Numerical Analysis and Engineering Judgment to Design Deployable Structures

Deployable structures are prefabricated space frames that can be stored and transported in a compact folded configuration and then deployed rapidly into a load bearing configuration. The structures are stable and stress-free in the folded and the deployed configuration, but exhibit a highly nonlinear behavior during deployment. Therefore, their design process should include simulation of their ...
