DAEDALUS (airfoil design and analysis software)

Daedalus is an interactive software for the design & analysis of airfoils; it was developed in Qt C++ by members of the Turbomachines & Fluid Dynamics Laboratory (TurboLab-TUC). Standard (NACA) and non-standard airfoils can be produced and simulated; the non-standard ones are either introduced from an embedded airfoil database (containing hundreds of airfoils) or parametrically defined using a NURBS definition procedure (using an external file with the distribution of either interpolation points or control points in the two sides of the airfoil). Additionally, a Free-Form Deformation (FFD) procedure is used to parametrically modify existing airfoils; a modified area-preserving FFD procedure can be also utilized. The analysis of each airfoil can be performed by (a) the well-known XFoil software (developed by Mark Drela), (b) an in-house Euler solver, (c) an in-house Navier-Stokes solver. The mesh generation around each airfoil is based on the Delaundo software (developed by Jens-Dominik Müller). The visualization of the computational grid and the produced results is based on the VisIt software.
