Orange Slice

Orange

The 2011 Orange Team truly did lead the way in innovation.  Pioneering the blended-wing body  for remote-control aircrafts and inventing new ways to manufacture structural and propulsion components, this design was complex, sleek, fast, and strong.  The design incorporated span-loading of the batteries, which allowed for the airplane to sustain 27 G’s in a turn.  In addition, the blending of the wing and fuselage eliminated most interference drag and gave the airplane a very sleek appearance.  Other innovations include welding battery cells into new configurations, creating a shear web that wraps around the components housed in the central wing/fuselage, and perfecting the “live hinge.” Because of all these factors, Plane #8 was able to set the OSU speed record to date at 195 mph.

Contest Summary: 

This year's contest was build entirely around speed and agility.  There were only two missions that the plane had to compete in.  The first mission was a pylon race.  The plane had to perform 10 laps in a figure "8" pattern around two pylons spaced 600 feet apart.  The second mission was a straightline speed calculated by measuring the time it takes the plane to fly from one pylon to the other, averaging a northbound and a southbound run to eliminate the effects of wind.

The team was limited to using electric propulsion only, 11.1 Volt nominal voltage as a source, and running the entire propulsion system through a 40 Amp fuse.  The team was further limited to designing a plane that can takeoff without human touch.  Only the propeller and batteries could be changed between missions.

Total score was calculated by adding the percentage of the team's best scores in each compared to the team in the lead, and then dividing by two.  For example, a team that was leading in both missions would score a 100, but a team that was leading in one mission but was 5% below the leader in the other mission would score a 97.5.
