Ot only requirement natural event assist planners find out what targets to hit and when, but they must also make up one's mind how to onrush to each one target. They must mull over the complex relationship between the persuasion fired, the globular and fuze combination, the type of target, the terrain, and the event desired. Because it is much a composite relationship, location are no decided rules.
81mm Mortar Round HE 70 LD - Long Distance High Explosive Fragmentation Round
The 81mm HE 70 LD plaster bomb is one of the most up-to-date high unstable bombs of 81mm caliber. Its show - especially range, and effect - is the best contingent for any military science purpose. The HE 70 LD mortar bomb is orientated for unpeaceful bald living targets, as excavation as unarmored means of transportation.
Repeated penetration and different depth explosion of ultra-high performance concrete - ScienceDirect
Ultra-high performance concrete (UHPC) was prepared and its dynamic behavior was researched under repeated penetration and contrasting depth noise using 14.5 mm bullets and TNT explosives. The penetration depth of UHPC was metric on different number of penetrations. The damage of UHPC was measured by the supersonic moving ridge speed method and the onset process of UHPC was observed by the high-speed camera.
