Presentation Outline Problem Definition Project Description Design Norms Important Resources Engineering Analysis Feasibility Study Results Obstacles and Accomplishments Questions 2/19 Team 1: On Wings Like A Penguin

Problem There are some situations where neither aquatic vehicles nor land vehicles can access certain locations In these situations an amphibious vehicle that travels above the surface could reach these locations Team 1: On Wings Like A Penguin 3/19

Build an amphibious air cushion vehicle Should seat two passengers Two engines: one for thrust, another for lift Approximately 12 x 6 ft, triangular shape Lift engine will duct air into skirt using air splitters Project Description Team 1: On Wings Like A Penguin 4/19

Design Norms Humility – The project is not perfect Integrity – Carefully crafted Transparency – Easily understandable and operable 5/19 Team 1: On Wings Like A Penguin

Important Resources Professor Heun Universal Hovercraft Homebuilders Showcase The Internet (Various Sites) The Hekman Library Brian, Friend of Dave Ryskamp 6/19 Team 1: On Wings Like A Penguin

Thrust Propeller Analysis Determined propeller tip speed would not exceed the speed of sound Calculated craft drag forces and determined required propeller pitch Calculated angle of attack along the propeller blade 7/19 Team 1: On Wings Like A Penguin
