You can make this prototype of free flying glider for your kids, nephews, or just for yourself. May it be the trigger for you to design more excellent new one. Just for fun ............haaa haaaa haaaa.
|Make a body from a square cut wood with the dimension beside (L=50cm
x W=0.75cm x T=1.5cm). Cut the bottom rear side, about 20cm from the rear
to become 0.5cm thick.
Note that the 3cm of the front side is cover by the tin layer lead for the balancing. Don't put it right now. Put after every part already combine.
|Make wing parts from a thin wood (the dimension is about 10cm x 10cm x 0.5cm). There are 4 pieces of wing parts.|
|Make fin parts also from a thin wood (the dimension is about 10cm x 7.5cm x 0.5 cm) and also for the standing fin (the dimension about 5cm x 7.5cm x 0.5 cm). Only one needed for each part.|
|Cut the wing parts and fin parts like beside picture. This is the most difficult part. The cut must be a stream line cut, so the air can pass smoothly.|
|Make a curve cut for the wing both sides like beside picture. Remember that, each wing side has an opposite direction. Then cut the both side to make a sharp point (become taper). Leave the rest two pieces as it is.|
|Make a curve cut both sides for the fin part (the big one). This is for the flat part. Then taper one side for the other. This is for the standing fin. Make a cut relief like beside picture.|
|All the four wing parts are assembled with the slope of 10 degrees for the inside parts and 25 degrees for the outside parts. You can use a triangle wood to support this wing. Make this section first, before assemble the whole parts together.|
|Assembly all the parts together like beside and below picture. Note that, wing is placed at the center of balancing point (15cm from the nose glider). The fin placed at the rear side closely.|
|After the assembling done, make a balancing point between the front side and the rear side. Put a tin plate layer in front of the glider. use a nail or glue to keep it tightly.|
|After everything is done, then it is the time to fly it for the first time. Hope it can fly without problem. How to fly this glider? You see the above picture. Moving direction must be against the wind direction. So if you throw the glider while running, then the glider will rise and then reverse side, follow the wind direction. If you are lucky, your glider will make a somersault in the air. Happy playing!!!|
