The idea was especially attractive because it was low cost, added little weight, and required little retrofitting. For the FAA test, the explosives-containing suitcase was placed near the bottom of the container close to the sloping panel. The explosive blast and attendant fragmentation ripped through the foam offset, the LD-3 aluminum wall, and the skin of the aircraft. It also caused some damage to 31 BLAST-RESISTANT CONTAINERS FIGURE 5-1 Cargo hold for blast testing HULDs. the floor beams. Thus, despite the positive results from Bruntingthorpe, the test under the FAA blast criteria was an obvious failure.
Maintain blast mitigation ability after airline “in-service” trial. also any potential fire. This Galaxy container meets all of the FAA design and blast criteria and has been certified. The FAA Transport Airplane Directorate Certification Office documented the certification on July 29, 1998 (FAA, 1998). A second Galaxy Scientific design passed the FAA blast test required for certification in January 1999. The first prototype of the Jaycor HULD was tested in March 1998. In this test, the HULD failed because of separation of the composite ceiling material and the failure of the container door.
Both companies decided to meet this requirement through blast tests. Prior to 1997, the FAA and industry had conducted numerous blast tests on earlier designs and had developed test standards (ISO 6517) for the two candidate HULD designs. , airframe, stringers, skin panels, shear clips, wall liners, cargo floor beams, and passenger floor beams), as shown in Figure 5-1. Although most of the major aircraft systems had been removed, much of the wiring, cables, and air ducts were intact. Each HULD was placed separately into the cargo-hold area at a standard container lock-down location.
