  1. Full Scale GBI Testing with B747 SP July 17-18, 2001International Aircraft Systems FireProtection Working GroupWilson, NC AAR-422 Fire Safety R&D

  2. Background • Focus of the Testing is to Better Quantify the Parameters that Effect the Benefit of GBI • Wind and Weather • Equipment Usage • Cross Venting • Study Manifold Design • Study the Cost and Benefit of Potential OBIGG Systems. • Platform to Examine Cross Flow Reduction Methods AAR-422 Fire Safety R&D

  3. Boeing 747 SP AAR-422 Fire Safety R&D

  4. Work Completed • Wrote Research Plan and Testing Safety Plan • Have a Preliminary Schedule • Start Testing 8-6-01 • Test for 12 Weeks • Obtained Aircraft • Located Preliminary Parking Spot • Have Most Support Equipment Required • Began Installing Testing Control Center and Instrumentation. • CWT has Been Opened and Cleaned and is Ready to be Modified AAR-422 Fire Safety R&D

  5. Instrumentation Planned • Gas Sample Tubing • Sample Oxygen at Eight Locations in the CWT • Sample THC at Any Two of Those Locations • Sample Oxygen in Surge Tanks, Dry Bay • Thermocouples • 8 in Fuel • 8 in Ullage • 16 Mounted on Interior Wall Surfaces • Plan to Measure Pressure in Tank Bays • Record NEA Volume Flow and Oxygen Concentration AAR-422 Fire Safety R&D
