  1. Science Olympiad Summer Institute Phoenix, AZ July 16 – 20, 20112 Rotor egg drop

  2. DESCRIPTION: • Construct a helicopter type device to safely transport a raw chicken egg from a given height to the floor

  3. EVENT PARAMETERS • Use wings/blades that rotate around a central axis to slow decent • No energy producing mechanisms • No pre-made rotor assemblies • Cannot be: • Airplane • Balloon • Parachute

  4. PARAMETERS (cont.) • Grade A large chicken egg • Sealed in plastic bag • Placed in cup • 8 – 10 oz • Foam? • Attached to device by tape Egg, bag, cup, and tape provided by event supervisor

  5. PARAMETERS (cont.) • Cup is 1st surface to touch the floor • Devices where cup does not touch floor first will be ranked below other devices where cup does touch the floor first • No other shock absorbing material allowed • Devices must fit w/in 51 cm x 51 cm x 51 cm

  6. COMPETITION • Impounded before start of event • No modifications allowed other than to attach egg • Students may inspect egg • If cracked may request another egg • Once accepted if broken before drop students may receive another egg • 2 sec. penalty subtracted from final time

  7. COMPETITION (cont.) • Only one drop • Height announced day of tournament • 5 meter minimum • Time – release time until it hits floor • 3 timers – MEDIAN of the 3 times • (the middle time is used)

  8. COMPETITION (cont.) • After drop student removes egg from device and gives to supervisor • All devices with eggs surviving will be ranked ahead of devices with broken eggs • even if student breaks the egg after the drop and before giving to supervisor • Broken egg defined by wet spot on paper towel

  9. SCORING • Highest time wins • Devices not meeting construction parameters will be ranked below all devices that do • Devices with broken eggs will be ranked below successful devices • Tiebreaker • Lightest helicopter (w/o egg, bag, cup) • No appeals after device leaves impound

  10. Practice • To practice without wasting eggs, take a plastic egg and weight with pennies to approximate mass of egg • Plan on making lots of different rotor designs. • Rotors must rotate at least 360 degrees in its descent or it is not a rotor it is a parachute • The higher the drop, the easier it is to get rotor to rotate 360 degrees • Angled blades rotate better than flat blades
