摘　　要：Future large-scale radio telescope observatories,such as the next-generation Very Large Array,involve extremely large collection areas.These collection areas are divided into smaller shaped panels,which typically require their own unique molds to manufacture.For these projects to be cost-effective,an efficient fabrication method for the shaped panels is needed.This paper outlines the development and success of a novel adaptive freeform panel molding technology that greatly improves manufacturing efficiency due to its repeatable and reusable nature.Moreover,it presents an analysis of a proposed panel structural design for the shaped panels,which incorporates a study on surface deformation due to gravity and wind loading under realistic operational conditions.
