  1. The Factors Effecting Golf Ball Aerodynamics Harrison DiGia Harry Kucharczyk Period 0,1,7

  2. Need • Techniques can be applied to more significant problems • Flow Control • Airplanes • Gas Turbines • Active Dimples

  3. Knowledge Base • Types of Flow • Laminar vs. Turbulent http://www.aviation-history.com/theory/lam-flow.htm

  4. Knowledge Base • Flow around Smooth Sphere http://www.aerospaceweb.org/question/aerodynamics/q0215.shtml

  5. Knowledge Base • Flow around Dimpled Sphere (Golf Ball) http://www.aerospaceweb.org/question/aerodynamics/q0215.shtml

  6. Literature Review • Hexx Ball • Conventional Ball http://hexxgolf.com/science.html

  7. Literature Review Golf Ball Suspension System http://eng.monash.edu.au/uicee/worldtransactions/WordTransAbstractsVol5No3/23_NjockLibii15.pdf

  8. Literature Review Smooth Dimples Steep Dimples (Kato, 2005) http://pdf.aiaa.org/preview/CDReadyMAAC06_1186/PV2006_2996.pdf

  9. Literature Review

  10. Formulas FD = [ 1 – FL/mg ] mg tan 0max

  11. Purpose • Examine the Effect of Golf Ball Characteristics

  12. Hypotheses • Null Hypothesis- The golf balls will all travel the same distance and have the same accuracy • Alternate Hypothesis- The golf ball with the most dimples will travel further and be less accurate

  13. No Dimples 332-336 Dimples 392 Dimples 432 Dimples Nike One Platinum Titleist Pro V1x Precept Laddie Titleist N-X-T Tour Wilson Ultra Precept Lady Caesar Dimple- less Ball Calloway Big Bertha Nike TA2-LNG Nike Spin and Control Attach to Golf Ball Suspension System (GBSS) Libii (2006) Record Angle at Different Wind Velocities Analyze using statistical analysis Methodology

  14. No Dimples 332-336 Dimples 392 Dimples 432 Dimples Nike One Platinum Titleist Pro V1x Precept Laddie Titleist N-X-T Tour Wilson Ultra Precept Lady Caesar Dimple- less Ball Calloway Big Bertha Nike TA2-LNG Nike Spin and Control Launch In Golf Ball Launcher Record Distance in yards and accuracy in yards (Measure +/- from designated line) Analyze using a scatter plot graph as well as ANOVA (p<.05) followed by a Scheffe Post Hoc Test Methodology
