3. Matthew Wright Team Manager/Seating Position/Steering James VanBiervliet Frame Dante Mucaro Drivetrain/Frame Integrations Rich Nelson Fairing Advisor: Dr. Lisa Grega Co-Advisors: Dr. Norman Asper Dr. Manish Paliwal Team Members

4. Project Management, Seating Position, and Steering Matthew Wright

5. Assisting other team members with all aspects of the project build Making sure parts and materials are ordered and ready when needed. Making sure the project is staying within budget, Completing application process for competition Keeping the team website up to date <TCNJhumanpowered.blogspot.com> Management

6. Senior Project 2 Gantt Chart

7. Modified frame design from mock up due to the rider position Ordering a 20” solid front fork with disc brake mounts Will weld mounts for other front brake Begin manufacturing steering assembly Rider Position and Steering

8. Frame James VanBiervliet

9. Frame A full scale model was created from wood

10. Frame Using the finalized dimensions obtained from model, a roll bar was designed

11. Frame The frame was then broken down into elements and nodes

12. Frame Pieces of bamboo were then cut according to the list of elements

13. Drivetrain & Frame Integrations Dante Mucaro

14. Drivetrain Revisions Gearing 50-34T crankset replaced in favor of 50-36-22T triple ring crankset 10spd 11-28T cassette replaced with 9spd 11-34T cassette Crank arm design modified to collar-type adjustable crank mount

15. Table of Gear Ratios

16. Comparison 27 available speeds vs. previous 20 speeds Broader range of gearing “Granny” gear equivalent speed decreased ~40% Top gear equivalent speed increased ~13.5% Negligible cost impact

17. Twin Disc Front Hub Twin disc mounts for standard 6-bolt rotors Machined from 6061 aluminum stock

18. Current Drivetrain Status Components ordered Cassette, crankset, bottom brackets, single sprockets, chain, derailleur (F&R), rims & spokes, brake rotors & calipers, shifters, cables Front hub and wheel construction To be completed by March 8 Crank arm implementation To be integrated into frame structure prior to frame completion Rear dropout fabrication Design to be finalized and implemented prior to frame completion

19. Aerodynamic Fairing Rich Nelson

20. Design and construct, respective of constraints, a single-rider recumbent fully faired human powered vehicle. Compete and win the 2010 ASME East Human Powered Vehicle Challenge. Aerodynamic Fairing - CFD Velocity Contour Plot Pressure Streamlines

21. Aerodynamic Fairing - CFD #1 #2 #3

22. Aerodynamic Fairing – Plug Construction Took cross sections from CAD model Made wooden cross sectional templates

23. Aerodynamic Fairing – Plug Construction Using wood templates to shape foam into plug Next – Sand plug smooth, prepare for Vacuum Bagging

24. Aerodynamic Fairing – Fabrication Vacuum bag layup of both halves of Fairing Cut out top hatch of fairing and wheel cutouts Integrate fairing into the frame and fiberglass halves together
