The evolution of rapid airplane-level design analysis continues. It is desirable in preliminary design, for example, to quickly generate and analyze a finite element model representing airplane structure. The Weight engineer typically creates a distributed mass model, representing the anticipated weight of the design, for use by other engineering disciplines. This paper outlines the approach taken to automate the generation of a mass model representing airplane systems and equipment. Arguments are made for extending this knowledge-based approach to other components of the mass model. Estimating weight from the model sizing data is not discussed, in favor of concentrating on the mass modeling technique. The knowledge-based modeling approach makes it possible to quickly create highly detailed mass models for use in rapid airplane design.
