  1. Human Powered Submarine

  2. Introduction • The submarine’s general characteristics • The hull • Propulsion system • Fins • Propeller • Security system • Direction system • Conclusion • Questions??

  3. Introduction • The team • Previous speed records • Our goal

  4. General Characteristics • One person, Propeller • Modeling done with CATIA V5R19 • The hull • Smallest in volume (105 in x 20 in x 24 in)

  5. General Characteristics • The propulsion system • Similar to Omer4 • Pedaling = rotor movement • Variable pitch added • The direction system • Four fins • Fully mechanical system

  6. General Characteristics • The security system • Same as Omer7 • Pneumatic system with actuators • Dead man switch

  7. The hull • Constraints • Methodology • Ergonomic test • Hydrodynamic analysis • Fabrication • Results

  8. The hull (Constraints) • Minimum required space for pedaling • Size of the pilot • Dimensions of the constraints

  9. The hull (Modeling) • CATIA V5R19 • NACA series 6 airfoils • Technique • Horizontal airfoils(shoulder and foot width) • Vertical airfoils(hip length and minimum length) • ellipses

  10. The hull (Ergonomic test) • Enough space? • Sectional analysis -Knee fitting -Shoulder and tank fitting -Pedals fitting

  11. The hull(Hydrodynamic analysis) • Computational Fluid Dynamics • Floworks by Solid works 2007 • Simulates a fluid at a speed of 4m/s • Trajectory of fluid + power of drag • Optimal results

  12. The hull(Fabrication) • Resin infusion process • Saves time and $$

  13. The hull(Fabrication) • Carbon fiber+ epoxy resin • Difference: carbon/innegra fiber • Nose window = polycarbonate(Lexan) • Good impact resistance+ translucent

  14. Results • Final hull • NACA66020 for vertical plane,NACA63013 for horizontal plane

  15. Propulsion system • Modeling • Description • Technical specifications • Variable pitch • Functionality of the variable pitch • Fabrication • Electrical system

  16. Propulsion system(Modeling) • CATIAV5R19 • Bearings • Bevel gears • Seals • Motors • Etc.

  17. Propulsion system(Description) 1- Plate glued to the hull 2- Structure support 3-Top cover plate 4-Driveshaft tube 5-Bottom cover plate 6-Gear box

  18. Propulsion system(Description) 1-Pedal 2-Crank set level 3-Lateral cover plate 4-Bearing housing 5-Lateral structure 6-Button bracket 7-Big bevel gear 8-gear box case 9-Button bracket bearing 10-Small bevel gear 11-Drive shaft 12-Drive shaft bearing 13-Drive shaft tube support

  19. Propulsion system(Technical specifications)

  20. Propulsion system(variable pitch) • In dependent electrical system • Holds two blades at a certain angle 1-Head cone 2-Rotor cone 3-Turning plate 4-Hub 5-Cover tube 6-Driveshaft

  21. Propulsion system(variable pitch) 1-Electrical motor 2-Motor support 3-Head cone seal 4-motor bushing 5-Rotor cone seal 6-Propeller blade bearing 7-Battery pack 8-Bevel gears 9-Bearing 10-Water proof connector 11-Electrical board

  22. Propulsion system(variable pitch) • Angle of the blades for best acceleration • Electrical system (pcb + code) • Magnetic switch + direct programing • Rpm = angle • Reajusting

  23. Propulsion (fabrication) • Mostly fabricated within our facilities • Standard bicycle parts • Aluminium

  24. Fins and propeller • Polyurethane casting • Aluminum moulds • Fabricated on CNC at 12000 RPM (4hrs) • Aluminum • Clouds of points and aeronautics airfoils

  25. Direction • Fully mechanical • Joystick on rails + cables • Direction on joystick= Direction of sub

  26. Safety system • Pneumatic • Dead man switch • Same air source as pilot
