Aeolus Aero Sketch Pad (ASP) is a free aerodynamic design application for UAVs, drones, and light aircraft. It allows you to easily model arbitrary fixed-wing aircraft concepts and to optimize model parameters (such as wing shape, or flight condition) to meet your design requirements.
Aeolus ASP allows you to test innovative ideas, see the impact of design changes in almost real-time, explore the design space, and to optimize your design concept on your computer. It applies an innovative boundary element method designed for best-in-class computational speed and fidelity, which ultimately enables efficient screening and optimization of new aircraft design concepts.
The graphical user interface (GUI) provides a toolbox for pre- and post-processing. In preliminary design, the designer typically needs to modify the aircraft shape many times to explore the design space. Therefore, the aircraft model in Aeolus ASP is fully parametric and provides direct access to geometry parameters, making it very simple to apply changes and re-run analysis within seconds.
Post-processing features particularly include 3D surface pressure plots, surface flow vectors, flight mechanics properties, tabulated forces and performance indicators as well as plots of all major aerodynamic coefficients.
A built-in optimization feature has been developed for Aeolus ASP taking advantage of the computational efficiency and the parametric design. With only a few clicks you can set-up your optimization problem and automatically search the design space for the best solution. Depending on your problem structure, you can choose between the BOBYQA algorithm, and the CMA-ES algorithm, respectively.
