  1. 2009 UCSD Human Powered Submarine Team Stanley

  2. Team History 1999 – 2000: “Subsonic” Set new world record speed of 3.47 knots New unique non-propeller driven design. Utilizes an “underwater rowboat” motion • 6 previous Submarines • Brother Submarine: Odin’s Rage • Team: • Faculty • Non-Faculty • Undergraduates

  3. Project Management • Stanley Plan • Design and Fabricate within 1 years time • Divide the project into 3 constituent parts • Drive Train/Propulsion • Hull • Pool Testing/Computational Modeling

  4. Drive Train Design • Simple and Effective • Leveraged linear slide system • Historically established propulsion methodology • “Drebel” • Linkage system harnesses pilot’s quadriceps and gluteus maximus in unison. • 60 degree Power Stroke • Feathered paddles allow for minimal losses during the return stroke.

  5. Drive Train Construction • Unique binding system for pilot’s. • Adaptive paddle mount system allows for propulsive improvement • The break away oars/paddles makes transportation easier as well as creates less of a risk for damage.

  6. Hull • Ready made solution • Classically streamlined body • Secondary sections • Special order acyclic nose cone • Hand rolled aluminum tail cone

  7. Pool Testing • Purpose of pool test • Establish hull strength • Find • Center of pressure • Center of gravity • Pilot ergonomics • Subs water weight

  8. Computational Modeling Estimated top speed 3.4857 Knots • Solving the governing equations of Fluid Dynamics for a complex flow is difficult. • Approximate dominant propulsion dynamics • Matlab Simulation • Momentum transfer • Paddles displace water mass • Water mass travels rearward at average velocity • Average velocity of water mass can be calculated by accounting for forces • Drives trains inertia • Paddle and oar drag forces • Paddle and oar bending due to drag forces • Assumptions • Average Human Power Output • 224 Watts for short term (5-10 min’s) bursts • Turbulent flow

  9. Safety Features • Quick release hatch - just pull! • Simple two-step pilots foot binding release • Spare airs in case the pilot’s main air supply fails • Clearly-marked safety features for support divers • Warning markings on moving boom and paddles

  10. Lift based propulsion Sophisticated emergency float Minimize drag from hull and propulsion Computer controlled guidance system Future Goals

  11. Matlab simulation Materials science Fluid mechanics Industrial engineering Professionalism Lessons Learned

  12. Sponsors US Grants
