  1. NASA Fire-Prevention Update International Aircraft Systems Fire Protection Working Group by Clarence Chang & Bob McKnight NASA Aviation Safety Program (AvSP) Fire-Prevention Element Leader March 26, 2003 Phoenix, Arizona IAFPWG: CTC

  2. Quick 5-minute briefing Aviation Fire / Fuel Security Workshop State of the NASA OBIGGS/OBOGS contract Alternate OBOGS technology leveraging Fire-safe fuel research status IAFPWG: CTC

  3. Aviation Fire / Fuel Security WorkshopMarch 11-12, 2003, Alexandria, VA Scenarios: Shoe bomb, API sniper round through tank, MANPAD Technologies: Fuel foam, solid polymer fuel, active suppression reticulated foam, inerting, MCK, metal mesh Board evaluation of ideas to help NASA sort out technologies for security program from FY04-07. Security program Aircraft Hardening Fire Prevention: 1 to 2 M /yr funding: IAFPWG: CTC

  4. OBIGGS/OBOGS Program Status • Retarget from B757-200 to B737-700 • 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 IAFPWG: CTC

  5. 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 (20-25kft) 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.T.Chang@nasa.gov IAFPWG: CTC

  6. Fire-Safe-Fuels Research Status • Established test methodology to produce repeatable low- • energy ignition tests • – level-field for world-wide fuel test comparison • – coordinating effort with FAA and DoD • 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.Rabinowitz@nasa.gov IAFPWG: CTC
