3. Types of kite What Kite we chose Kite test Purpose of delta kite How to make a kite Why we chose delta kite Analysis of how our kite went

5. Why it looks this way Deer horns represent longevity and good luck. Tigers eyes, the tiger is the king of the beasts, mighty and strong. Catfish whiskers, to represent the material wealth. A humans beard, as a symbol of intelligence and talent.(The longer the beard the wiser you are). The segmented body represents a snake. With a dragon kite all the lift is created by the tail segments. The feathers are essentially stabilizers. In strong winds the tail rises almost vertically. They can tolerate very high wind speeds, can be flown in 25 mph winds. They can range from a small dragon with a 3.5m tail, or up to a monster, with 80 m tail.

6. The Diamond kite is probably the most recognized type of kite in the world It is shaped like a diamond A tail is needed to keep it balanced The tail allows it to be stable and reliable

7. This kite is primarily used for the enjoyment of young children Its easy to fly and handle in the air While in the air the kite catches the wind and creates an area of low pressure giving the kite lift VERY FUN!!!

9. - High-performance kite that reaches relatively high heights - This type is a cellular kite - The typical design has four parallel struts - The box is made rigid with diagonal crossed struts - There are two sails, also known as ribbons - Each sail is a quarter of the length of the box - The ribbons wrap around the ends of the box, leaving the ends and middle of the kite open - Sails help stability during flights

10. Usually have triangular wings. Spars on the leading edge of the wings which can pivot on the spreader bar One or more longitudinal spars help the kite to keep its shape. spars can be made stiffer and stronger if necessary A keel is usually used but is not always necessary. A high-wind Delta kite will have its towing point more towards the nose of the kite.

11. Usually designed to fly in light wind. The ability to fly at very high line angles. Used at festivals. Used for surveillance

20. Figuring out wind direction Not enough wind Kite was too heavy Removed wooden dowel Kite got more lift
