  1. ISR #11 University of California, San Diego Odin’s Revenge and Legasea

  2. Introducing UCSD HPS • Building Submarines for 12 Years • ISR #10 • Odin’s Rage (1 person, non-prop) • 2nd Place with Max Speed of 4.103 Knots • 16 Member Team

  3. Developmental Timeline • Finished ISR #10 • Started Design for Legasea • Finished majority of Design on Legasea • Began Fabrication of Legasea • CATASTROPHY! • Improved upon Odin’s Rage

  4. Overview of Legasea • Two-Manned Design • Two Propeller Propulsion System • Reduced Drag from Previous Subs • Still in Progress Rear Recumbent Pilot Front Prone Pilot Dual-Crank, Dual-Prop Propulsion

  5. Hull Design of Legasea • Modified mold of Odin’s Rage • Lengthened hull by 6 feet • Reduced Frontal surface area by 17% • Designed with Manufacturability and Maintenance in mind

  6. Drivetrain Design for Legasea • Dual-Propeller Drivetrain • Center-Mounted • Dual-Crank Mid-Ship Props Cranks (90° out of phase)

  7. Hull Production of Legasea • Fiberglassing • Vacuum bagging with UV Resin • Created a male plug and one portion of the hull

  8. Failure of Mold During Fabrication • Catastrophic mold failure • Complete Chunks of Mold Torn Out • Long Fracture Lines • Shifted priorities of team • No time to repair and finish Legasea • Decided to race Odin’s Revenge instead

  9. Overview of Odin’s Revenge • One-Manned Design • Utilizes Fin Propulsion System • Easily adjustable harness allows for different pilots Entry Hatch Steering Surfaces Pilot Window Fin Propulsion

  10. Improvements to Odin’s Rage • Improvements in Securing the Pilot • Change in Steering Interface • Redesigned Fin System • Newly Redesigned Boom

  11. Propulsion

  12. SafetyFeatures of Odin’s Revenge • Quick Releases on Main Hatch and Belt for Both Pilot and Safety Divers • Redesigned Dead-Man’s Switch to increase both reliability and safety

  13. Testing and Training • Setbacks from Legasea production allowed for increased time to test Odin’s Revenge • Able to fine-tune new additions to submarine

  14. In Conclusion • Problems with Legasea Development • Shift in Team Focus • Improvements to Odin’s Rage
