human powered flight - vertical take off, flexible wing
I'm interested in contacting groups or individuals who are working on
human powered vertical take-off vehicles or ornithopters. I have a number of design ideas I would like to share and get feedback on and I am also interested in materials. Some of my ideas are as follows: 1. Wings made of light, strong, sandwich-layered foam like Voltek mini-cell. 2. Wing density gradually decreases toward the middle of the material, or if 3D printed, the wing density can be varied precisely to translate motion from each part of limb to surface of variously shaped wings. 3. Leg wings, tail or whole body fin (like a ray) add lift. 4. Thickness of wing tapers gradually away from body so edges are sharp and flexible. 5. Full body Crawl or Doggypaddle style stroke evenly distributes effort to every muscle group and force over the greatest possible area. 6. Wing silhouette is rounded 3x5 rectangle used from corner to corner. 7. Leading edge of Wing curled down and trailing edge curled up so cross-section is s-curve and figure-8 wing-strokes apply constant force downward. (no upstroke) 8. Sharp corners in wing design possibly tapering to spirals. 9. Standing take-off, like a pidgeon. I am in the Washington DC area, so I would be especially interested to hear from locals, but others too. Patrick Timony |
