Aviation Safety Program Accident Mitigation Project OBIGGS/OBOGS Program Status • Retarget from B 757 -200 to B 737 -700 • 6 -month feasibility study finishing on 3/26/03 • No new technology entrant: • Higher-Temperature membranes • System-level performance improvement • Oxygen waste stream for emergency-cruise breathing • Phase II evaluation and selection by 4/26/03 • Enough funding for 3 of 4 proposed Phase II contracts 4 26 March 03 IAFPWG: CTC

Aviation Safety Program Accident Mitigation Project Alternate OBOGS Application • Currently no suitable means for OBOGS to satisfy surge load • Surge load requires some form of stored oxygen • Higher-altitude emergency cruising (20 -25 kft) requires better membrane selectivity or PSA-type enrichment • Enriched oxygen for hybrid fuel-cell APU • All-electric airplane requires larger electrical load • Electrical generation from more efficient fuel-cell • Oxygen-enriched waste stream increases power density • Lower pollution -- Clean APU exhaust • Contact Clarence Chang at 216 -433 -8561 Clarence.

Aviation Safety Program Accident Mitigation Project Fire-Safe-Fuels Research Status • Established test methodology to produce repeatable lowenergy ignition tests – level-field for world-wide fuel test comparison – coordinating effort with FAA and Do. D • Establish a surrogate Jet-A blend from pure substances for ignition-reduction additive testing. • Raise flash point another 20 F • Contact Marty Rabinowitz at 216 -433 -5847 Martin. J.
