Project 2 Practical Application Kite

Project 2 Team #5Practical Application KiteBy: Cathy, Meteb, Matt, & NathanTo make a kite thats stable, efficient, and can stay in the air for the longer period of time to take accurate air temperature measurements.

NeedUse for Task- For our kite, the goal is to create a kite that can take the temperature measurements of the air.Suitable for the Task- The kite must be stable, and can fly easily under any weather conditions.Helps Manage Resources The kite must be environmental friendly and be made of recyclable materialsTechnology Feasible- Whether or not the accessory is capable of working.Possible Cost- The least costly kite with accessory.Safety- Making sure that the accessory is secure to the kite while on the ground and in flight.RequirementsSled KiteDiamond KiteBox KiteDelta KiteOptions

This kite has a basic, easy design.The shape is produced mostly by the pressure of the wind.Without wind the kite might collapse.The cover is made of polyethylene.Due to the ease of design, it is mostly used for childrens recreation.The original type of Sled has 2 straight spars running the length of the kite

Diamond Kite

Basic shape = simple triangleTwo thin dowels or spars along each wing edgeAnother dowel for the spineAnd a fourth dowel intersecting the spin and fixed to each wing edge A triangular keel is also present along the spine from which the string is attached

Delta Kite

Abox kiteis a high performancekite, noted for developing relatively highlift.The typical design has four parallel struts. The box is made rigid with diagonal crossed struts. There are two sails, whose width is about a quarter of the length of the box. The sails wrap around the ends of the box, leaving the ends and middle of the kite open.
