Aeolus - Aero Sketch Pad

Aerodynamic Optimization Toolbox

FAST modeling, analysis, and optimization features for Aircraft DesignERS BASED ON AN INNOVATIVE 3D PANEL METHOD

Aeolus Aero Sketch Pad (ASP) is an aerodynamic analysis software package, designed for Windows PC. It allows designers to easily model aircraft concepts and to automatically optimize wing shapes to a specified objective.

 

Released in 2018, Aeolus ASP offers best-in-class computational speed and fidelity based on a innovative 3D panel method for aerodynamic analysis. Unlike conventional CFD software, the computational costs for modelling and analysis with Aeolus ASP are in the order of seconds, allowing the designer to explore the design space, test innovative ideas, and to optimize the aircraft design on a Windows PC.

Easier Modeling - Faster Analysis - Optimization

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.

Built-in Shape Optimization

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.


Fast analysis for preliminary aircraft design

Challenging performance requirements and short development cycles for new aircraft require efficient tools for preliminary analysis and optimization of aerodynamic properties. At the same time, new missions and technologies increase the design freedom and enable novel aircraft concepts.

 

Therefore, Aeolus ASP is particularly suitable for the conceptual and preliminary design phase, where fast computation is crucial to evaluate a large number of design alternatives and to ultimately find the optimum.


A key innovation in Aeolus ASP is an advanced panel method kernel which was developed for best-in-class computational efficiency and fidelity. In conjunction with feature-based design, this finally allows engineers to change design variables and to evaluate the effect of these changes on aerodynamic characteristics in almost real time. Improve productivity with Aeolus ASP and take advantage of deeper design space exploration for more informed decisions and better products.

 

Aeolus ASP is ideal for aircraft design engineers , engineering consultants, hobbyists, R&D centers, and academia. More specific examples include Product development (Unmanned Aerial Vehicles (UAV) / Unmanned Aircraft Systems (UAS), light sport aircraft, sailplanes, model aircraft, hang gliders and paragliders), Academic R&D (multidisciplinary aircraft design optimization, morphing wings, radical new aircraft concepts, formation flight), but also yacht sails, race car spoilers, and fast illustrations of new concepts.
