Previous Research

Diamond Kite:

It is the most recognizable kite and probably the most popular, due to its stability and reliable flying characteristics. Simple to make, requiring only a diamond shaped piece of cloth and 2 rods. They are usually less than 1 meter long. Sail is modernly made of nylon, plastic, or polyester.

Previous Research

(Traditional) Box Kite:

Made of 2 long straight spars running the full length of the kite, the diagonal braces which made the whole structure rigid, and the flat cloth sails giving it the unmistakable 'box' appearance.

Previous Research

Foil Kite:

Like most land-based kites these days, rip-stop nylon is the usual sail fabric. These surfing kites have upper and lower surfaces, with ribs sewn in between to form cells. When in flight, air pressure inflates the cells, giving the kite a wing-like shape that generates lift. Just like an aircraft wing. The designers have taken care of kite-surfers here by providing an extra feature. Inlet valves! They can be flown in a wide range of wind conditions

Previous Research

Dopero Kite:

Has a reputation for being an excellent light wind flier. It flies at high line angles like a Delta, and yet has very good stability and lifting capacity as well. Modern Doperos are often constructed from Rip-stop nylon sail material and carbon fiber spars for minimum weight. The Dopero kite is basically 2 Pearson Roller kites side by side.

Design Of Dopero

Dimensions Of Dopero

To make our kite larger, we multiplied all dimensions by 3.

Construction

Used wooden rods, plastic canvas, tape, hot glue, and string to construct our kite.

Folded canvas in half, and cut out a template.

We then added supports, tape and glue for structure

And then added string for control.

Testing Flight

Improvements

Add a keel

Use different adhesives to make the kite more lightweight

Change the positions of the strings to make it support more of the kite while in flight

Make sure that the kite sail was fully attached to the rods

Increase size to make it easier to catch wind
