SCIENCE OLYMPIAD Wright Stuff – B 2009-2010 Matthew Chalker & CeAnn Chalker matthew@chalker.orgceann@chalker.org
Wright Stuff Basics • Allowed 2 Ultra light aircraft built and tested prior to competition • Flown indoors • Timed for duration aloft • No Impound • Aircraft to be labeled with team’s identification name & number • Must be a monoplane with single propeller assembly
Wright Stuff Basics • Allowable Materials • Wood, paper, plastic film covering, carbon fiber, and glue • Thread, wire, plastic tubes & rubber bands may be used to attach major components • Any dense material for ballast • Flight log for 10 previous flights before beginning their test flights at competition
Power for Plane • Plane launched from hand • Plane powered by wound rubber band • Uses a propeller
Building Specifications - • Total mass of plane must be at least 7.0 grams (without rubber motor) • 40.0 cm max horizontal projected wing span • maximum wing chord – no limit • 28.0 cm max horizontal projected stabilizer span • maximum stabilizer chord – no limit
Building Specifications • Propeller • Single two-bladed commercially made plastic propeller • Maximum diameter of 20.0 cm • Trimming, shaving, twisting allowed • Rubber Motor • 1.5 grams maximum mass (includes O-rings) • Only 1 motor per flight allowed
Flight Log • 6 parameters for 10 previous flights prior to competition • 3 required parameters • Motor size before windup • Winds on the motor at launch • Flight time • 3 Additional parameter examples • Turns remaining at landing • Estimated peak flight height • Estimated flight path diameter • Torque at launch
Competition • 8 minutes to launch their 2nd flight after their 1stdeclared official flight begins • Motors impounded after check-in, are available only for official flights • Teams must declare before any launches during the 8 minutes if it is an official flight or a trim flight. If not declared any launch will be considered official.
Competition • During 8 minute Flight Period teams may: • Make adjustments & repairs • Launch trim flights • Qualify additional motors • Timing will be to the hundredth of a second • Timing ends when any part of plane touches the ground or comes to rest on any obstructions (even if prop continues to rotate)
Competition – • Competitors only allowed in testing/flight area • Test flights allowed throughout competition at the discretion of the Event Supervisor, ending at least by the last 30 mins. of the tournament • Test flights will yield to official flights • Multiple aircraft may test fly at once
Scoring - • Winner is team with the longest flight time for any single flight • Ties broken by second flight time
Bonus – WS • State – 30% of the flight time will be added if the plane’s wing chord measures less than 7.0 cm • Nationals – 40% of the flight time will be added if the plane’s wing chord measures less than 6.0 cm
Deductions & Violations – • Flight Log discrepancies • Incomplete flight logs will have 10% of the flight time deducted from each flight • No flight log will have 30% of the flight time deducted from each flight • Rule Violations without a specific penalty will be ranked after all teams that do not violate the rules
