Penetration of shaped charges into frozen ground -- 2
Shaped charges of special design with 4 in. diam and weighing from 2 1/2 to 3 1/2 lb were fired into frozen ground at Fort Churchill, Manitoba; data were obtained on effect of standoff, charge weight and cone material, thickness, and angle; results of testing showed that hole 5 ft deep and 1.7 in. in diam in frozen ground can be obtained with shaped charge weighing 2.8 lb, and that aluminum cones are superior to copper or steel cones; additional studies were recommended on weight and shape of charge, fabrication of copper and steel cones, and validity on cube root scaling for shaped charges.
