  1. NASA KC-135 Flight Georgia Tech Aerospace Engineering October 24, 2001 Dynamic Behavior of Surface Tension in Microgravity

  2. Agenda • NASA RGSFOP Program • 2001 Georgia Tech Microgravity Team • Experiment Overview • Experiment Setup • Flight Day 1 • Flight Day 2 • Data Reduction • Continuation of Project • Acknowledgements

  3. NASA’s Reduced Gravity Student Flight Opportunities (RGSFO) Program Students submit scientific experiment proposals If selected, spend a week in Houston and fly proposed experiment aboard KC-135 NASA RGSFO Program • KC-135 Weightless Wonder • a.k.a the “Vomit Comet” • Flies in parabolas to simulate weightlessness • Used primarily for astronaut training

  4. 2001 GT Microgravity Team Courtney Spells – Team Leader Robert Coffman Jordan Drewitt Alisa Hawkins Judy Kim Daniel Uhlig Advisor: Dr. Jerry Seitzman

  5. Experiment Overview 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 • Practical Applications • Further research in quick deployment of liquid shapes in zero-gravity environment

  6. Design and Construction • Box Design for liquid containment • 3D design done using Pro-E • Box built in AE Machine Shop • Ground Testing • High Speed camera test • Absorption test • Popping and procedure test

  7. Pre-Flight in Houston • Test Readiness Review • Lectures • Motion Sickness • Tours of NASA • Hypobaric Chamber Ride Taken to simulated altitude of 25,000 ft to experience hypoxia

  8. Flight Day 1 • Flyers • Robbie Coffman • Daniel Uhlig • Tested - Balloon sizing • ½, 1, 1½, 2 fluid ounces • Found - 2 fluid ounce balloons were most favorable • More liquid for viewing • Less shearing effect

  9. Flight Day 2 • Flyers • Courtney Spells • Alisa Hawkins • Experiment Parameter • Varied Liquids Used • Water • Milk • Water/Soap • Olive Oil • Jello • Video Taped Motion of liquids during deployment

  10. Video

  11. Data Reduction • Drops Vibration • V vertical diameter • H horizontal diameter V and H versus time (frames) v H

  12. Data Reduction • Different types of liquids

  13. Data Reduction • Different Sizes (Water) • Drop 1 (red) is twice as big as drop 2 (black Dash line is vertical Solid line is horizontal

  14. Continuation of Project • 2002 Microgravity Team submitted follow-up flight proposal last Friday • Recommendations to 2002 team • New popping method which does not have such a shearing effect • High Speed camera • Better measurement techniques
