3. Agenda Problem Statement Background Information Deliverables Scenarios Considered Constraints Customer Requirements Engineering Requirements House of Quality Preliminary Project Schedule Issues and Corrective Actions

4. Problem Statement Current State: • Boeing’s current UUV, the Echo Ranger has a maximum mission time of 28 hours. Boeing would like to significantly extend this mission time. Desired State: • Boeing would like to utilize a thermoelectric system to significantly extend mission time of their UUVs. Project Goals: • Demonstrate proof of concept of thermoelectric system • Use a temperature differential to charge a battery • Achieve maximum thermoelectric efficiency over a range of temperatures • Establish a UUV-based research partnership between Boeing and RIT Constraints: • System must operate underwater • System must utilize a thermoelectric device • System must operate autonomously

5. Background Information Boeing’s UUV, Echo Ranger • Developed in 2001 for seafloor mapping for oil/gas industry • Currently testing the idea for potential military applications • ISR • Harbor security • Current run time • ~28 hours

6. Background Information thermoelectric module picture thermoelectric IV curve

7. Deliverables Functional prototype which demonstrates proof of concept for an underwater thermoelectric device Appropriate design, test, and integration documentation to support eventual inclusion in a UUV Test data verifying engineering requirements have been met

8. Use Scenarios Thermoelectrics have low efficiency • They need a lot of heat supplied 2 Options: Radioisotope Fuel Cell

9. Constraints Economical: • Budget Range - $950-$1800 Technical: • Underwater Operation • Power generation - must be accomplished by the use of thermoelectrics • Size - details have not been furnished

10. Customer Requirements Continuously generate power Charge a battery Operate underwater Heat source provided a constant source of heat Waterproof System can withstand desired water pressure

11. Engineering Requirements Power Output Heat Source Power Input Upper Ambient Operating Temperature Thermal Overload Protection System Operates Without User Input

12. House of Quality Continuously Generate Power Charge a Battery Waterproof

13. Project Plan

14. Issues and Corrective Actions Lack of defined engineering requirements - heat source, battery voltage, etc. • Obtain information from Boeing or design our own Little communication with the end customer • Find a direct contact with Boeing Completion of group tasks • Ensure all group members are notified of current statuses (Drive Notifications)
