ESKIMO III. Magazine Separation Test
Abstract
In an instrumented test in June 1974 at the Naval Weapons Center, approximately 350,000 pounds of Tritonal explosive contained in M117 bombs were detonated simultaneously within a steel-arch, earth-covered igloo flanked by two adjacent igloos and near three other igloos located with varying degrees of face-on exposure and at varying distances from the donor blast. The principal objective was to qualify the oval steel arch igloo at the minimum side-to-side spacing now permitted for standard earth-covered magazines. Test results indicated that the range tolerated by the oval steel arch igloo covers the minimum standard distance in feet equal to 1.25 X W to the (1/3) power, in which W is the weight in pounds of the high explosive in storage. Additionally, the results showed the single-leaf sliding door to be effective whether mounted on a new structure or on an existing headwall. The test also included investigation of the response of a new light-gauge, deeply corrugated steel arch and further investigation of separation distance standards, of safety distances specified for public traffic routes, and of the hazards associated with window glass used in commercial and institutional buildings. The report contains data on igloo damage and structural motion, air blast pressures at the site, and vehicle and window damage.
