Method of Obtaining a Massive Hypervelocity Pellet from a Shaped Charge Jet.

摘要

A method of isolating the tip of a shaped charge jet is described. The tip, thus isolated, provides a massive pellet for research in the field of hypervelocity impact. Aluminum pellets of 3.2 to 4.0 grams mass with velocities between 7.57 and 10.95mm/micro sec (25,059 and 35,478 ft/sec) were produced with a 3.33-in. diameter Composition B charge. For one charge design, in which sufficient observations were made, the standard deviation of the velocity was only 0.10mm/micro sec. Shaped charge scaling laws predict that pellets in the order of hundreds of grams can be ejected at equivalent velocities. (Author)
