RESPONSE OF DRAG TYPE EQUIPMENT TARGETS IN THE PRECURSOR ZONE
Abstract
The conclusions which may be drawn are summarized by the following statements: Considerable damage data on various vehicles, combat and transport, were obtained. Damage was most extensive on a desert surface. From the displacement measurements and damage, the drag forces are higher on the desert surface than either the water or asphalt surface. Considering the effect of positive duration, the results show that scaling factor for damage radii be as W0.40 when the yield of weapon is varied and the scaled height of burst range is between 80 and 500 ft. An incident overpressure of about .25 psi in the regular reflection region is required to produce significant damage to jeeps from shock loading only. Protection against drag forces can be achieved when the item is placed behind a barri cade which in itself can withstand high drag forces. The roll-over safety bars placed on the vehicles helped minimize cab and body damage. Certain design features can be incorporated in the design of ordnance equipment which will minimize the damage. The average attenuation of gamma radiation by armored vehicles, the M48, T97, and M59 are 0.1, 0.6 and 0.7 respectively. The lethal radii for personnel from gamma radia tion extends farther than blast damage radii for the armored vehicles.
