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
||||||||||||||||||||||||||
Hovercraft Basics
• A hovercraft (or Air Cushion Vehicle) uses pressure differentials to lift itself off of the ground
||||||||||||||||||||||||||
Software Tools
• Modeling program – Autodesk Inventor
||||||||||||||||||||||||||
Software Tools
• Finite element analysis – Algor FEMPRO
||||||||||||||||||||||||||
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
