[WIP] Soaring Stars Lab: DAD (Digital Airfoil Designer)

1 Like

DAD software let you make, modify and test airfoils or hydrofoils in a simple and fast way. It includes a no dynamic bat interface to run Xfoil and read the result. It will be a commercial product.

DAD is a Digital Airfoil Designer VR CFD editor tool in beta stage for drawing propeller blade, sail, wing sections profiles and testing aerodynamic characteristics in a Digital Wind Tunnel. Specific software for the subsonic field of fluid mechanics. The coefficient results are displayed into charts. It lets you run XFoil in a simple user interface and run a virtual wind tunnel 2D CFD in Windows PC.

  • Re
  • Min and Max alpha
  • Alpha Steps
  • Nc turbulence
  • Airfoil editor via sliders
  • Symmetric airfoil option
  • NACA airfoil series interface
  • Automatic airfoil panelling
  • Chart: alpha lift
  • Chart: drag coefficient and cdp
  • Chart: LD efficient as a function of alpha or lift
  • Xfoil data info display
  • Load and Save DAD format
  • Export .dat airfoil file.

More to come:

  • Artificial intelligence is responsible for choosing the best result autonomously.
  • VR capabilities to expand the user experience (angle of view)

The UI is superb! It looks like a control panel for the Death Star. What do you use for drawing curves and graphs?

Thanks. Yes, and the branding logo has the same feeling of that saga. Iā€™m old; from b/w TV and green monitors. Xfoil is Fortran77 so I try to maintain the visual spirit. I make some research first and then I sketch up the initial idea . For excitement, I added bloom post process effect. I try to make a healthy useful UI without adding superfluous information.

AIRFOIL
In YouTube, I search and found NurFACEGAMES Bezier Curves in Unity. The airfoil is made up using 4 curves using line render and a camera. Control points are in a fixed axis. A camera picks up the final image and transforms it into a render texture. I use that airfoil texture in the UI.

CHARTS
I purchased from the Unity Asset Store, Toucan Systems Smart Charts simple to implement and somehow I was able to work around bugs. Later I purchased BitSplash Interactive Graph And Chart what looks like a more promising better option but is not integrated yet.
