  1. NASA KC-135 Flight Georgia Tech Aerospace Engineering October 18, 2001 Dynamic Behavior of Surface Tension in Microgravity

  2. NASA’s Reduced Gravity Student Flight Opportunities (RSGFO) Program College and high school students submit scientific experiment proposals If selected, fly experiment aboard KC-135 What is the KC-135? • KC-135 Weightless Wonder • a.k.a the “Vomit Comet” • Flies in parabolas to simulate weightlessness • Used primarily for astronaut training

  3. Our Experiment Dynamic Behavior of Surface Tension in Microgravity • Basic idea • View the dynamic motion of liquids of varying surface tension in zero-g • Objectives • Determine the frequency at which liquids oscillate • Determine a dampening effect

  4. Experimental Setup • Liquids used Water, water and soap, milk, olive oil, and Jello • Liquid deployment Popped balloons with needles • Liquid Containment Housed in a sealed container with access by gloves

  5. Pre-Flight • Test Readiness Review • Lectures • Chamber Ride Taken to simulated altitude of 25,000 ft to experience hypoxia • Tours of NASA

  6. Flight Day 1 • Flyers • Robbie Coffman • Daniel Uhlig • Tested • Balloon size • Found • Large balloons popped the best

  7. Flight Day 2 • Flyers • Courtney Spells • Alisa Hawkins • Tested • Liquids of different surface tension

  8. Plane Motion Variables: a – acceleration t – time v – velocity g – gravity y – position What shape must the plane’s trajectory be in order to match the acceleration of gravity? Equations of Motion: a = -g ∫ a dt = - ∫ g dt ∫ a dt = - g ∫ dt v = - gt + Vo ∫ v dt = - g ∫ (t + Vo)dt y = -gt2/2 + Vo t + yo
