The question posed in the 2010-2011 AIAA Design Build Fly competition included three missions, each scored differently. The first mission required that the aircraft fly, without payload, around a predetermined competition course and complete as many laps as possible within a four minute flight time. The second mission required that the aircraft complete three laps with a payload of a steel bar. The bar was required to be a minimum of three inches wide by four inches long; the depth of the bar was determined by the team. The third and final mission required that the aircraft complete three laps with a team-selected payload of golf balls. For the first mission, the team focused on eliminating excess weight while maintaining structural integrity. The aircraft needed to be able to fly quickly and endure multiple g-force turns. For the second mission, the team carried that largest steel bar that would create a predetermined optimized payload ratio. For the third mission, the team maximized the number of golf balls carried through a trade study conducted in a MATLAB optimizer. The optimal number of golf balls was found to be three. Since all payloads must be carried internally, a fully defined fuselage was implemented. In order to uphold the design requirements for the first mission, the fuselage was made streamline and was constructed from ultra lightweight material. Extraneous weight was further eliminated by use of the lightest electrical components available.
