In a joint research project between the National Aerospace Laboratory (NLR) and the Faculty of Aerospace Engineering of Delft University of Technology (TUD) a multi-level system for the preliminary design of aircraft structures has been developed. The present system is essentially an extension of the existing Aircraft Design and Analysis System (ADAS). ADAS has been modified to allow the definition of major structural components like ribs, spars, frames, bulkheads, floor structures, and semi-automatically to generate models for air load calculations (panel methods, doublet lattice) and finite element structural optimization. The models can be automatically modified with changes in general design parameters such as wing area, sweepback angle, aspect ratio. In a study to evaluate the system, ADAS has been used to (re)design the principal structure of the Fokker 50.
