  3. Presentation Overview • Objectives • Hovercraft Basics • Initial Design • Design Obstacles • Refined Design • Future Improvements • Acknowledgements • Questions ||||||||||||||||||||||||||

  4. Objectives • Build a two person hovercraft • Land and sea travel • Attain speeds of 5 mph or greater • Craft weight must remain under 400 lbs • Fabricate as many components as possible • Make craft safe for operators and bystanders • Intuitive design ||||||||||||||||||||||||||

  5. Hovercraft Basics • A hovercraft (or Air Cushion Vehicle) uses pressure differentials to lift itself off of the ground ||||||||||||||||||||||||||

  6. Software Tools • Modeling program – Autodesk Inventor ||||||||||||||||||||||||||

  7. Software Tools • Finite element analysis – Algor FEMPRO ||||||||||||||||||||||||||

  8. Initial Design • Hull constructed from foam and wood • Two engines; one for lift, one for thrust • Triangular in shape, 6 ft x 12 ft • Bag style skirt • Air directed into skirt by splitters • Joystick style controls • Electronic engine shut off ||||||||||||||||||||||||||
