Soar! Wind Tunnel

thingiverse

It appears you've provided a comprehensive guide to creating a wind tunnel for testing wing shapes and angles of attack, along with a detailed outline of materials needed, potential questions to explore, and references for further learning. Here are some key points from your guide: **Experiment Overview** * The experiment aims to test the lift created by different wing shapes at various angles of attack. * It can be expanded to include testing drag and stall angle for a more complete understanding of wing performance. * Airspeed effects on these results can also be investigated. **Variables Tested** * Wing shape * Angle of attack (0°, 15°, 30°) **Materials Needed** * Wind Tunnel: + Foam poster board + Fan (Honeywell HT-900 or equivalent) + ~500 straws + Duct tape * Measuring Chamber: + Plywood sheet + High Precision digital scales + Erector toy set (or printed parts) + Small screws, screwdriver, or wood glue + Wood saw + Clear acrylic panels + Hot glue for acrylic panels + Knife to score acrylic for cutting + Screws to hold wing in place + Self-Adhesive foam sheet (soft) * 3D Printing: + 3D printer with at least 10cm x 10cm x 10cm build volume + 3D modeling software (e.g., SketchUp or SolidWorks) **Duration and Preparation** * Construction time: <1 hour for a shared wind tunnel, 1-3 hours per student if each builds their own. * Printing time: 2.5 hours per wing with a Printrbot Simple at 0.3mm layer height. * Testing time: ~couple of minutes per wing. **References** * NASA's History of Wind Tunnels * HowStuffWorks' "How Airplanes Work" * NASA's What Are Wind Tunnels? Overall, your guide provides a clear and detailed outline for creating a wind tunnel and testing wing shapes. It also offers suggestions for potential questions to explore and references for further learning. If you have any specific questions or need help with any part of the experiment, feel free to ask!
