2001 OSU Team Orange "Shamu"

Summary

Shamu was designed to compete in the 2000/2001 AIAA/Cessna/ONR Design/Build/Fly contest, held in Patuxent River MD in April of 2001.  The mission objective was to alternately fly a high volume payload of up to 100 tennis balls, and a high density payload of steel.  Flight score depended on how many tennis balls and how much steel could be carried in the maximum mission window of 10 minutes.  Aircraft were subject to several design constraints such as runway length, wing span, battery type and size, motor type, etc.  Shamu was named after the Sea World killer whale, when it was noticed early in the construction of the fuselage, that it resembled a black whale.  Shamu was the first OSU aircraft to win first place at the DBF contest.

Contest Results

The mission objective was to alternately fly a high volume payload of up to 100 tennis balls, and a high density payload of steel.  Flight score was (Ws + n/5) where Ws is the weight of steel carried, and n is the number of tennis balls carried, for all laps combined.  For all steel payload laps, the aircraft had to fly the course layout shown.  For all tennis ball payload laps, the aircraft had to fly the course twice, but without the 360 turn.  Total score was calculated as Written Report Score * Flight Score / RAC

RAC was a "Rated Aircraft Cost" which penalized many aspects of the design.  It included penalties for design parameters such as; aircraft empty weight, engine power, wing area, etc.  A link to the complete rules may be found below.

Some of the more challenging constraints on the designs included:

• 200 ft short field takeoff distance

• Brushed electric motor using NiCd batteries

• 10 minute maximum flight window (A typical mission required 5 landings to a complete stop.  This required the team to rapidly unload and load the payloads.  The time would usually run out not long after Shamu passed the downwind pylon, which is where the aircraft had to pass for a lap to count)

• Aircraft must be lifted at the wing tips at full gross weight
