Preliminary Design Methodologies

The AERODESIGN project provides a multi-segment and multi-level technical framework, aimed at creating an entire preliminary design methodology solution. An aircraft model, created from an historical data base goes through an integrated process of optimization at preliminary design level, integrating various modules, namely geometrical, aerodynamic, engine data, weight and balance, mission and low speed performance, cost analysis, engine emissions and noise analysis.

Aircraft design encompasses different areas of knowledge, ranging from aerodynamics to structures and flight dynamics. It is the combination of these areas of expertise, in a multidisciplinary environment, combined with design requirements that will allow a successful design. Combination of different fields where data/information is needed as input to another field of analysis automatically increases the number of design cycles necessary for the development of a product, increasing overall cost. Furthermore, at an initial phase of design, various unknowns are still present, data may be unavailable and requirements can suffer several changes, increasing the overall cost even further through more design cycles, creating the need for a tool/framework capable of performing initial and realistic analysis of different design solutions with little effort in a multidisciplinary design environment.

To promote flexibility and reusability in other projects, as well as to allow future evolution/expansion and updates, the AERODESIGN tool was designed and developed in a highly modular fashion. This approach and transparent interface also mean that the AERODESIGN architecture is easily integrated, as a whole or partially, into more complex aircraft design tools, namely in Multidisciplinary Design and Optimization (MDO) environments.
AERODESIGN is a Clean Sky Joint Technology Initiative research project in collaboration between Spin.Works, GMVIS SKYSOFT, S.A., Delft University of Technology and KE-works B.V. The research leading to these results has received funding from the European Community’s Seventh Framework Programme (FP7/2007-2013) for the Clean Sky Joint Technology Initiative under grant agreement nº CS-GA-2009-255851.
