Abstract:

A technique-development program was conducted with the ultimate goal of providing terminal ballistics data for hypervelocity fragments striking selected targets. Shaped-charge hypervelocity fragment projectors and instrumentation techniques were developed and tested which will permit the gathering of terminal ballistics data for fragments one grain and larger in size when they impact targets at velocities between 30,000 and 40,000 ftsec. The fragment projectors developed were shaped charges with conical liners of small apex angle 42 degrees, 30 degrees, 25 degrees, 20 degrees. Special designs and techniques were developed for separating the points of impact of the fragments, and for limiting, eliminating, or preventing undesired fragments. Instrumentation techniques included the application of flash radiographic instrumentation providing sequential and orthogonal v ews of the fragments immediately prior to impact, a high--speed framing camera observing the targetimpact process, and other auxiliary and supple-mentary equipment. The projectors and their performance, the instrumentation and its operation are described and briefly reviews the problems encountered and solutions provided during the development program. Some of the problems which remain unsolved, along with plans for their solution, are also discussed. Author
