Have you ever wanted to design your own aircraft? Think you could build something that would actually fly? John's Wing Designer gives you a chance to do just that without ever leaving your desktop.
Wing Designer provides a user interface that enables you to adjust 20 different parameters for a wing and the aircraft you plan on attaching it to. You choose the wing dimensions: wingspan (width), root chord length (center length), and tip chord length (edge length). You choose the airfoil, which determines the shape of the wing's cross-sectional area. Want your wings to slope back or bend like a V in the vertical? You can adjust the sweep and dihedral angles, too. Once you enter all the parameters, you push Calculate and get a prediction of your aircraft's range and payload capacity. Performance is summarized by an overall score...the higher the better.
When I was an undergraduate, I would have loved to have gotten my hands on this tool. It's a great way to quickly get a sense for how design choices impact system behavior. For giggles, I tried to reproduce the F-16 wing. A clean screenshot of my results are shown above. Below, I annotated the user interface to give you a sense of how the wing would be placed on the fuselage.
The tool doesn't have the exact airfoil used by the plane, but I was able to get good results with a 4412. I found that if I used a different airfoil at the tip, I could increase the aircraft's range and bump my score up a little. If anyone can find a pair of airfoils that top a score of 29252, please let me know!
