New Design of Deep Penetrating Bomb

摘要

The present article proposes two new designs of cases for deep penetrating bomb. The BLU-122 deep penetrating bomb (BLU-122 penetrator) was developed by the USAF in 2003 made improvements upon the BLU-113 penetrator which would enable it to have significant penetration through hard targets. The weapon incorporates more energetic explosive fill, higher strength case material, and modified nose shape for increased penetration. Despite the improved case, the BLU-122 possesses only 18-20ft (5.4-6.0m) penetrability in 5.0ksi (34.5MPa) strength reinforced concrete. A monolithic case made from new developed high strength steel provides more than 50% projected increase in penetrability in regular reinforced concrete of the BLU-122 penetrator compared to the standard case from the Eglin steel. A composite case made from the joined different super-high strength materials has several improvements compared to the monolithic case. Penetrator with the composite case is able to penetrate the Ultra-High Performance Concrete.
