Abstract
It is necessary to design the new concept of the space vehicles in order to survive the space market in the world. However, although concept design is particularly important in space vehicle development to add value and reliability, it is difficult to apply conventional shape-based CAD/CAE systems to the concept design stage due to the lack of detailed design information at that stage. In this paper, we suggest the new design method (Product and Operation design method) that can support concept design of space vehicles by many kinds of Products and Operations produced by orthogonal table. By using this design method, we can design space vehicles in comparison with another design plans, and design the new space vehicles (e.g., multi-purpose space vehicles, or constellation satellites.). The prototype system based on the design method is implemented, and some examples applied for the concept design of super-sonic vehicle "SEED" are shown.
