  1. The Effect of Mass of Helicopter and Length of Hanging Mass from Helicopter on Acceleration Abby Bault – Center Line Megan Satawa – Warren Woods Tower

  2. TABLE OF CONTENTS • Background • Problem & Hypothesis • Materials & Procedures • Data Collected • Odd Trials/Data • Statistical Tests • Conclusion • Errors Made • Real World Application • Further Research • Review • Questions

  3. BACKGROUND • Lift • Thrust • Drag • Weight

  4. LIFT • Force that causes helicopter to move up • Bernoulli Principle • Pressure increases as speed increases • Wings • Air flows around body: changes pressure and velocity • Through center of pressure

  5. THRUST AND WEIGHT • Thrust moves helicopter forward • Must be equal to weight • Weight is force of gravity – pulls down

  6. DRAG • Force that opposes motion • Created by contact with fluid • Skin friction: interaction between solid and gas • Acts through center of pressure

  7. BACKGROUND

  8. PROBLEM • To determine the effect of mass of helicopter and distance of hanging mass from helicopter on the acceleration of the helicopter.

  9. MASS

  10. DISTANCE

  11. HYPOTHESIS • If the distance of the hanging mass from the helicopter and the mass of the helicopter are the greatest then the acceleration will be the slowest.

  12. DESIGN OF EXPERIMENTAL VALUES

  13. MATERIALS • TI-nSpire • Meter Stick • Propel RC Toy Helicopter • Craft String • Propel RC Controller • Different Masses • Video Recorder                 • Timing Device • 18 AA Batteries

  14. PROCEDURES • Randomize trials and set up camera and meter sticks • Fly the helicopter and record the flight • Analyze the video using LoggerPro • Record the acceleration

  15. VIDEO

  16. DATA COLLECTED

  17. OBSERVATIONS • Outline trials with specific observations HERE

  18. ANALYSIS • Two-Factor DOE • Mass and string length

  19. STANDARDS

  20. EFFECT OF MASS

  21. EFFECT OF DISTANCE

  22. INTERACTION EFFECT

  23. CONCLUSION • Lack of statistical significant • Based of D.O.E analysis

  24. CONCLUSION • Scientifically significant results • Based on dot plot of effects Distance Mass

  25. CONCLUSION • Hypothesis: Accepted

  26. ERRORS MADE • Wrong weight on helicopter for DOE 1 • Trials redone • Lack of operating experience

  27. Design Flaws • Inconsistent helicopter battery power

  28. FURTHER RESEARCH • Different types of helicopters • Different factors • Humidity, air flow(turbulent or laminar) • jkda

  29. real world application • MedEvac Flights • Emergency Rescue
