  1. ‘Mjolnir’ Vehicle Testing Results PSU2011 Human Powered Vehicle Tad Bamford Ben Higgins Chris Schultz Aaron Stanton Neal Pang

  2. Overview • Concept • Design Specifications • Final Design • Prototype • Testing (HPVC) • Failure Analysis

  3. Final Design • Based on decision matrix: • Three-wheeled “tadpole” style recumbent • Energy storage deemed unfeasible • Partial fairing • Hub-centered wheels • Leaning Frame

  4. Energy Storage vs. Fairing • Energy Storage Device to heavy for power gain • Fairing More effective for speeds above 10 mph

  5. Carbon Fiber Hub-Centered Wheels • Manufacturing • Testing • Analysis

  6. Testing • Due to leaning mechanism, vehicle was unstable and counterintuitive to ride. • Lockout employed • Further testing showed instability

  7. The HPVC http://www.nbcmontana.com/news/27897784/detail.html

  8. The HPVC • Redesigned Steel Front End

  9. Failure Analysis • What Went Wrong • How it Could Have Been Prevented
