Introduction: Building a Hang Glider

 After looking back on my instructable i have realized how stupid my idea was. I have been over designing. I am going to leave the instructable up, but do not take anything in this particular design too seriously. Look at them mearly as ideas.

  I wish to start off this instructable by saying that this is not a tutorial on making a hang glider. Instead i have made it to show what i have been doing to make one and to hopefully inspire you and to help me to get some ideas from you as to how i can change my design to make it more efficent, less costly and easier to but together. ( I will post a instructable once i have made a hang glider i am pleased with. )

I also want to say that hang gliding can be dangerous to those who do not know what they are doing. If you decide to build this or any moving machine really, work with caution

   Gereral ideas in my design:
- A large piece of plastic sheeting is placed over a frame made of heat treated bamboo succured by sewing it over on itself over the 2 poles making the leading edge.
- The bamboo is succured by a fiber glass structure on each attachment that is fixed to only one of the poles in the attachment. The other pole can slide out of the attachment to allow it to be transported on the top of a car.
- The leading edge is kept in shape by a bunch on dog food bags put together, shaped and glued to strengthen it. 13 small tubes are glued onto this said structure to help secure the bamboo ribs. (The ribs will fit into the small tubes and the other end of the bamboo ribs are placed into small pockets sewn into the trailing edge of the sail.)

Step 1: The Frame

   The frame is made of heat treated bamboo. The whole thing has a wing span of ~8.5m. The 2 poles making up the leading edge are ~4m. long and go off at an equal angle from the "wing keel". The wing keel is ~3m. long and is attached perpendicualy to a very long pole meeting the 2 leading edge poles about half way down. The ribs are shaped like an airfoil with a flat tailing edge like a up aileron to help keep the whole thing stable.
   The poles making up the frame are attached by fiberglass; made in such a way as to let one pole in the attachment detach from the attachment while the other pole is fixed to the attachment. (The pole that is detachable from the joint is sanded down to alow it to slide out of the fiberglass joint more easily. Screws are placed into the attachment to help hold the lose pole.)

Step 2: The Sail

   The sail is made of a plastic tarp/sheeting. (I prefer white/clear sheet.) It is stretched tightly over the frame and permanently attaches to the leading edge poles and the wing keel. The attachment over the leading edge follows from the tip all the way down to the tip of the wing. The edges are first covered in a layer of duct tape to prevent the sail from ripping. Then the edge is folded under the leading edge pole and is sewed to the part of the sail directly above it. (which is also layered in duct tape.) In other words the sail is sewed to make a tube that the leading edge pole can slide through. The attachment to the wing keel consists of another strip of plastic tarp. This piece is also sewed to the direct middle of the sail and fits tightly around the wind keel pole. (once again you use duct tape.) The very tip of the sail is attached just by a hell of a lot of duct tape (unless i can get any other suggestions. Or maybe fiberglass.)

Step 3: The Ends of the Leading Edge

   At the ends of the leading edge are 2 carbon fiber rods. (I plan to use some of my uncles old hunting arrows. They are cheap and strong.) One sticks out of the leading edge at about a 100 degree angle. The other acts as a brace and attaches to the end of the previous stick and to the leading edge pole about a foot down from the previous's sticks attachment to the edge. These poles could be attached to the sail by the folding over method i explained twice before. 

Step 4: A-Frame

   The second to last piece is a isosceles triangle that attaches to the wings C.O.G. (Center Of Gravity) This acts as the steering mechanism and controls pitch, yawn and roll. This is also made of heat treated bamboo and is about 3 feet wide and 4 feet tall. The top of the frame where the two equal length poles meet is attached to the  wing keel about 2 feet up from the frame's C.O.G. by a final fiberglass attachment. This piece must be firmly attached so the bottom two ends of the 3 foot pole are attached to the ends of the poles to the sides and to the front by high-tension wires.  

Step 5: The Harness

   The harness is a rock climbing harness that is modified to fit on backwards and attaches to the persons C.O.G. and to the Gliders C.O.G. It allows you to hang parallel to the wing keel and to pull yourself forward and to push yourself back using the a-frame.

Step 6: What I Need From You

    As you can probably tell, i do not know much about building flying machines. So, I need your help to build this glider. I am asking for suggestions and professorial advice regarding to how to make the hang glider
- Stronger
- Safer
- More controllable 
- More portable
- And more efficient

Thank You.
