Airblast Damage to 30-kW, Skid-Mounted, Mobile Army Diesel Generator Sets

摘要

A 30-kW, skid-mounted electric generator set of the tactical Army type was tested for structure-only damage under the impact of airblasts with peak pressures of 9.3 and 3.5 psi. Conclusions based on test results apply to three tactical models of 30-kW, skid-mounted, diesel generator sets available for Army field use. Test results indicate that generator sets will operate without interruption when exposed to an airblast with a peak pressure of 3.5 psi. If the impacting peak pressure is 9.3 psi, the operation of the generator sets could possibly be interrupted because engine parts, generator terminals, and control circuits are damaged from major deformation of the access doors. Recommendations for low-cost hardening emphasize redesign of doors and other sheet-metal structures for survival under combined airblast and thermal pulse conditions. (Author)
