Reaction Structure

 

Application

Science. Near zero CTE antenna segment for large radio telescope.

Previous limiting technology

Steel and/or aluminum has too large of a thermal expansion coefficient and would be too heavy for a large, moveable structure.

Challenge

Design and engineer a near zero CTE, out of Autoclave antenna segment while maintaining adequate strength, stiffness, and affordability. A primary target was low cost, a very aggressive target.

Solution

Rock West carefully researched affordable materials that fit into the performance requirements and then created design concepts that kept labor hours restrained. The final design met stiffness, CTE, and cost requirements. Design study, testing and analysis were incorporated.
