Wing weight estimation using an automated CAD-model
(English)Manuscript (preprint) (Other academic)
Advantages and possibilities offered by modern CAD tools in conceptual design are discussed. In order to illustrate these possibilities, a Computer Integrated (CI) method to estimate weight in conceptual design is presented. The CI method is based on geometry and simple load analysis; the weight is determined from a 3D computer model. The CI method is a compromise between empirical methods and time-consuming methods based on finite element analysis. The CI method allows investigation of unconventional and conventional configuration, and possibility of creating different structure layouts. The method has been applied on commercial aircraft for validation. The presented results have been compared with, other available methods in conceptual design. In addition to weight estimation, modern CAD programs offer integration and data exchange with other domains such as computational fluid dynamics, system simulation and production analysis and planning.
