• 1. Possible Kite Applications• 2. Selection of a Kite Application• 3. Selection of Kite Type• 4. Chosen Kite Design• 5. The flight of our Kite

• Transportation/Propulsion Kite– Large 160 square meter

kites are being used to reduce fuel costs for large commercial ships by 20%. These sail kites are steered by a computer system allowing optimal wind power.

– A smaller version of this system could be adopted for personal transportation such as skateboards.

Meteorology Kite• Kite would contain a

thermometer, wind speed and direction gauge, barometer, and UV index measurer, among other things

• Would have to be made out of lite materials to support the equipment including a wire frame and lite fabric

• Shaped in a square for stability with UV index on top and the rest of the equipment residing inside the box along with a transmitter to relay data to the ground

Energy-Generating Kite

• Will use a small fan mounted on the kite to generate electricity

• Energy will be stored in a small lightweight Lithium-Ion battery on the kite

Aerial Photography

• The Dopero Kite design is great for an aerial photography application because of its ability to lift a lot of weight with light winds.

• These kites can raise straight upward potentially 150 meters in the air making it perfect for taking a picture.

Our Design

• We have chosen to use the Dopero Kite design.

• The is due to the fact that it takes up a small amount of materials.

• Also, it also is simple enough to be done in our limited amount of time.

The Dopero Kite

• Dopero stands for Double Pearson Roller.• This kite is designed by combining two

Pearson kite designs to make one large, stable kite.

• This kite design is typically seen used either for entertainment or for aerial photography.

=

The Dopero Kite Cont.

• It can lift a lot of weight, which serves our purpose of lifting a camera.

• It is also best known for being an excellent kite for flying in light winds.
