Boomerang

  1. 1. • Australian Aborigines• the language of the Indigenous Australian Turuwal tribe• Oldest - 30,000 years
  2. 2. WEIGHTFORCE DRAG LIFT
  3. 3. • BERNOULLI’S PRINCIPLE (AIR FOIL)• COANDA EFFECT
  4. 4. Right handed boomerang Left handed boomerang
  5. 5. Gyroscopic effect
  6. 6. One of the wings produces more lift compared to the other whichcreates a moment about an axis perpendicular to the axis of rotationof the boomerang thus creating the gyroscopic precession.
  7. 7. • Weltner, Klaus and Ingelman-Sundberg, Martin - Misinterpretations of Bernaulli’s Law; Physics of Flight• Saulius Pakalnis - Aerodynamics of Boomerang• www.researchsupporttechnologies.com• www.grc.nasa.gov
