Abstract: A process and apparatus which can be packaged in a warhead for disseminat a finely divided high explosive by means of a burster charge into the atmosphere as an high explosive dust-air cloud bomb. By interposing a damping means between the explosive burster charge and the load of particulate high explosive, the explosion of the HE explosive inside the container by the burster charge is prevented.

Abstract: A device for calibrating cubes which are used in the determination of the magnitude and pressure of an air blast having a base, a pedestal mounted on the base, a pendulum pivotally attached near the top of the pedestal, a box end for holding the cube at the end of the pendulum, a timing device for determining the velocity of the pendulum during its swing, and a bumper for stopping the pendulum when the pendulum is vertical so as to impart an initial velocity of Vo to the cube whereby the calibration factor of the cube can be determined. Another embodiment provides a metallic block instead of the box end in which case the cube is struck by the block end of the pendulum thus imparting initial velocity Vo.

Abstract: An apparatus for protecting a surface from a projectile having a series of eactive armor plates disposed substantially adjacent to one another and substantially covering the surface to be protected. The reactive armor plates each have an upper inert plate having a front planar surface and a back planar surface, a lower inert plate having a front planar surface and a back planar surface and a high explosive having a front planar surface and a back planar surface sandwiched between the upper inert plate and the lower inert plate. The upper inert plate has a plurality of holes between it's front planar surface and it's back planar surface and the lower inert plate also has a plurality of holes between it's front planar surface and it's back planar surface.

Abstract: A blast focusing technique for producing high pressure on a ground plane, in which a right circular cylinder of explosive material is positioned adjacent the ground plane with the cylinder axis orthogonal to the ground plane. The cylinder is simultaneously detonated at both ends by detonators disposed on the cylinder axis at each end of the cylinder.

Abstract: An improved shock tube generates a reflected wave of an adjustable magnit which arrives at a test object located within the shock tube at the same time that a rarefaction wave arrives so as to cancel the rarefaction wave thereat and counteract the undesirable effects of the rarefaction wave, thereby achieving a reliable free-field simulation.

Abstract: A system and method for wide-area mine clearance employs a plurality of f-containing plastic containers disposed a horizontal distance apart which permits an overlap between adjacent aerosol clouds formed therefrom when explosive bursters are simultaneously detonated within each container. At least one detonation charge is exploded within one of the aerosol clouds following a predetermined time delay for detonating the line of overlapping clouds whereby a line of ground surface is exposed to a fuel-air explosion capable of detonating susceptible mines therein. The distance between adjacent containers and the height each container is suspended above the ground is related to the weight of the liquid fuel contained in each container. In the preferred embodiment, each plastic container is suspended from a tripod having a hook or other means for permitting attachment and detachment of a crane hook whereby the tripod may be positioned over uncleared ground from a location well within cleared ground.
