Abstract
Recently, satellite system is getting more sophisticated and complex in order to meet the high mission requirements. The satellite engineers desire the design support system, by which specialist of structural designers and thermal designers can design concurrently, and by which the specialists can confirm the products to meet the requirements. In this paper, authors suggest a prototype design system for satellite by using XVL technology, which can integrate the design and structural/thermal analysis and which can reduce the capacity of input/output data for structural/thermal analysis.
