The purpose of this project is to extend the usable oxygen supply of aircrew walk around system with rebreather technology. The current systems provide too little duration (approx. 25 minutes) for aircrews to perform duties at altitude. This limited duration can be a safety and mission compromising as the aircraft may not be able to descend to a flight level where supplemental oxygen is not needed. These current systems function in an open circuit manner where each exhale is vented into the surrounding atmosphere wasting about 90% of the oxygen. Grey Wolf Innovations Inc. rebreather technology will allow the exhale to be captured and recycled to be breathed again, extending the oxygen supply beyond 2 hours. This closed circuit rebreather design packages in nearly the same size as the current system (22.8" x 8.1" x 6.8") and weighs only 12.3 lbs (includes Oxygen Tank, Regulators, CO2 Scrubber, Electronics, Sensors, Dilution System, Counterlungs and Pressure Relief/Venting System).
