Submarine Class
![Page 5: University of Washington Human Powered Submarine Systems Report Michael Thompson-Team Captain Brian Matters-Dive Captain](https://reader036.vdocument.in/reader036/viewer/2022062717/56649e495503460f94b3c5ce/html5/thumbnails/5.jpg)
Propeller Design• Goals and Assumptions– Single screw– Optimize thrust– Design for specific power requirement– Design parameters based on research over
intuition– Design for ease of manufactuing
![Page 6: University of Washington Human Powered Submarine Systems Report Michael Thompson-Team Captain Brian Matters-Dive Captain](https://reader036.vdocument.in/reader036/viewer/2022062717/56649e495503460f94b3c5ce/html5/thumbnails/6.jpg)
Propeller Research• Importance– Previous propeller design was based solely on
intuition– Specific revolution rates and power ranges were
needed– A way to evaluation propeller designs
• Propeller Dynamometer• Pilot Ergometer
![Page 7: University of Washington Human Powered Submarine Systems Report Michael Thompson-Team Captain Brian Matters-Dive Captain](https://reader036.vdocument.in/reader036/viewer/2022062717/56649e495503460f94b3c5ce/html5/thumbnails/7.jpg)
Propeller Dynamometer• Test scale model propellers• Provide physical data• Compare and evaluate computer models
![Page 8: University of Washington Human Powered Submarine Systems Report Michael Thompson-Team Captain Brian Matters-Dive Captain](https://reader036.vdocument.in/reader036/viewer/2022062717/56649e495503460f94b3c5ce/html5/thumbnails/8.jpg)
Pilot Ergometer• Better understand the human ‘engine’• Determine power output and rpm ranges• Optimize pilot ergonomics
![Page 9: University of Washington Human Powered Submarine Systems Report Michael Thompson-Team Captain Brian Matters-Dive Captain](https://reader036.vdocument.in/reader036/viewer/2022062717/56649e495503460f94b3c5ce/html5/thumbnails/9.jpg)
Propeller Selection• Airfoil shapes researched• Ergonomic data used to constrain design• Propeller design evaluated using CFD and
tested on Propeller Dynamometer
![Page 10: University of Washington Human Powered Submarine Systems Report Michael Thompson-Team Captain Brian Matters-Dive Captain](https://reader036.vdocument.in/reader036/viewer/2022062717/56649e495503460f94b3c5ce/html5/thumbnails/10.jpg)
Power Transmission• Design challenges– Previous system had extensive backlash and prone
to gear slip– Bearings degraded when exposed to water
• Goals– Reduce bearing friction– Properly design gear interface– Allow for transmission to be easily removable
![Page 11: University of Washington Human Powered Submarine Systems Report Michael Thompson-Team Captain Brian Matters-Dive Captain](https://reader036.vdocument.in/reader036/viewer/2022062717/56649e495503460f94b3c5ce/html5/thumbnails/11.jpg)
Gearbox Design• Sealed gearbox to eliminate fluid drag• Enclosed shaft and supports• One piece design
![Page 12: University of Washington Human Powered Submarine Systems Report Michael Thompson-Team Captain Brian Matters-Dive Captain](https://reader036.vdocument.in/reader036/viewer/2022062717/56649e495503460f94b3c5ce/html5/thumbnails/12.jpg)
Life Support• SCUBA component evaluation– Air consumption rates– Airway & breathing restriction
• Tanks size requirements– Staging and run times– Breathing rates
• Regulator selection– Pilot comfort
![Page 13: University of Washington Human Powered Submarine Systems Report Michael Thompson-Team Captain Brian Matters-Dive Captain](https://reader036.vdocument.in/reader036/viewer/2022062717/56649e495503460f94b3c5ce/html5/thumbnails/13.jpg)
Primary Life Support System• Tank– AL-40– Enough air for five runs
• Regulator– Ocean Reef G-diver– Full use of airway
![Page 14: University of Washington Human Powered Submarine Systems Report Michael Thompson-Team Captain Brian Matters-Dive Captain](https://reader036.vdocument.in/reader036/viewer/2022062717/56649e495503460f94b3c5ce/html5/thumbnails/14.jpg)
Emergency Air Supply• Design factors– Independent system– Removable in event of emergency accent
• Tank– Al 13 pony
• Regulator– Aqua Lung Titan LX

Safety Systems• Submarine paint scheme• Emergency egress• Diver restraints• Pilot visibility• Emergency beacon• Emergency buoy
![Page 16: University of Washington Human Powered Submarine Systems Report Michael Thompson-Team Captain Brian Matters-Dive Captain](https://reader036.vdocument.in/reader036/viewer/2022062717/56649e495503460f94b3c5ce/html5/thumbnails/16.jpg)
Paint Scheme
![Page 17: University of Washington Human Powered Submarine Systems Report Michael Thompson-Team Captain Brian Matters-Dive Captain](https://reader036.vdocument.in/reader036/viewer/2022062717/56649e495503460f94b3c5ce/html5/thumbnails/17.jpg)
Egress and Restraints• Egress was made to be as simple as possible• Pneumatic cylinders activate hatch release• Hatch release deployed with activation of
dead-man’s switch• Pilot is no longer actively restrained in the
submarine
![Page 18: University of Washington Human Powered Submarine Systems Report Michael Thompson-Team Captain Brian Matters-Dive Captain](https://reader036.vdocument.in/reader036/viewer/2022062717/56649e495503460f94b3c5ce/html5/thumbnails/18.jpg)
Emergency Beacon and Buoy• Beacon system– Beacon is attached to top of hull for
maximum visibility
• Buoy design– Buoy system is self contained to
ensure line doesn’t tangle– Buoy is spring loaded and deploys
with retractable pneumatic cylinder
![Page 19: University of Washington Human Powered Submarine Systems Report Michael Thompson-Team Captain Brian Matters-Dive Captain](https://reader036.vdocument.in/reader036/viewer/2022062717/56649e495503460f94b3c5ce/html5/thumbnails/19.jpg)
Hull Design• Design focus– Design and manufacture new hull– Renovate existing hull
• Existing hulls– Dubsub: sleek but cramped– Sirius: extra real-estate but large cross-sectional
area– CFD analysis
![Page 20: University of Washington Human Powered Submarine Systems Report Michael Thompson-Team Captain Brian Matters-Dive Captain](https://reader036.vdocument.in/reader036/viewer/2022062717/56649e495503460f94b3c5ce/html5/thumbnails/20.jpg)
Hull Selection• Team race goals– Optimize for speed– Research automated controls– Limited manpower
• Formally Dubsub– Internal frame structure– Modular design
![Page 21: University of Washington Human Powered Submarine Systems Report Michael Thompson-Team Captain Brian Matters-Dive Captain](https://reader036.vdocument.in/reader036/viewer/2022062717/56649e495503460f94b3c5ce/html5/thumbnails/21.jpg)

Summary• Team goals– Further research into Marine Engineering– Increase public interest in Undersea Research– Apply education through real world application– Encourage younger students to pursue science as
it relates to the marine industry– Reflect well upon the University of Washington
and strengthen the team structure for the future
