4. ●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 Problem Statement

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

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

13. Project Plan

14. ● 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) Issues and Corrective Actions
