Agenda Problem Statement Background Information Deliverables Scenarios Considered Constraints Customer Requirements Engineering Requirements House of Quality Preliminary Project Schedule Issues and Corrective Actions Problem Statement Current State: Boeings 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 Background Information Boeings 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 Background Information thermoelectric module picture thermoelectric IV curve 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 Use Scenarios Thermoelectrics have low efficiency They need a lot of heat supplied 2 Options: Radioisotope Fuel Cell 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
