Aircraft Design
Objective/Requirements The UAV team at Arizona State
University is designing, optimizing, and building an autonomous Unmanned Aerial Vehicle (UAV) to compete in a 2010 UAV aerial imaging contest.
The objectives of the contest are: (1) to fly an UAV via autopilot non-stop for 20-40 minutes in a square search area of 1 square miles, and (2) use onboard/remote human detectors to locate and identify targets marked by colored alphabets
Additional contest rules: (1) fly between 100 and 750 feet above ground, (2) fly over way points (GPS), (3) some targets are along route/some are not, and (4) better performance = higher score

Wing Design Flow Chart
Wing Design Analysis (cont)
Relatively good at floating. But not as fast due to the thicker airfoil (11.7%). Is flat on the lower surface from 30% of the chord back. It gives reasonable overall performance in respect of its lift to
drag ratio. Has gentle stall characteristics.
Preliminary Weight Budget
Researched Weights of components that were going to be used for building operating the aircraft.

Wing Design Analysis
From research, choose Wing Loading and used it to determine the initial size of the aircraft.
For ease of construction and stability considerations the Wing Loading for our aircraft is
