EFFECTS OF ROUGH TERRAIN ON DRAG-SENSITIVE TARGETS
Abstract
The objective of Project 1.8b was to investigate the blast damage sustained by drag-sensitive targets when the blast wave passes over rough, hilly terrain to the target location. Of particular interest was the difference in the damage sustained by those targets which were positioned to take maximum advantage of terrain irregularities and the damage sustained by those targets placed over level terrain at corresponding distances. For this study 51 jeeps were exposed on Shot Smoky. Vehicles were placed on three blast lines: a control line of essentially flat terrain, a line of rolling terrain, and a line of steeply sloping terrain with scattered gullies and washes. Earth revetments were constructed to examine the protection they would provide for vehicles. Project 1.8a made airblast measurements at each station. After the shot, the damage, orientation, and displacement of the vehicles were recorded. The results showed that the damage sustained by those vehicles on regular terrain agreed with the TM 23-200 damage chart. However, the damage sustained by those vehicles which utilized severe terrain irregularities was greatly reduced. Where any su1stantial obstacle, natural or artificial, having steep sloping rear walls was interposed between the detonation and the vehicle, damage was reduced from severe or moderate to light.
