Terminal ballistics

Description

Naval Weapons Center. China Lake. California. 1976. – 232 p.This book is based on lecture notes for a course offered at the Naval Weapons Center as part of its training program of day classes in science and engineering. Its publication was jointly sponsored by the Research Department and the Personnel and Organization Development Division, Personnel Department of NWC The course was designed to summarize the fundamental concepts of terminal ballistics for employees who would use the information directly in assignments in research, development, or analysis of weapons, or who would use the information as background in the planning and management of weapons programs. For this audience terminal ballistics is the science of the interaction of a ballistic weapon with a target and must include sophisticated warheads as well as the classical concepts of the defeat of armor. Typically the student was a recent engineering or physical science graduate; however, many technicians who were directly involved in weapon design and testing also took me course. For these and many others associated with ordnance science, there is a continuing need for an introductory summary of the main phenomena of the detonation and fragmentation of explosive warheads and of the phenomena of high-velocity impact and the techniques for measuring and predicting the extremely rapid and intense exchanges of energy and momentum that occur in the interaction of a warhead with a target. Warhead design and analysts will often require the development of these concepts beyond this introductory level. The object here is to provide the starting point horn which the direction for further development will be more clear. The book begins with the ballistics of gun-launched projectiles, the subject matter of classical ballistics, and develops from this base a parallel description of warhead phenomena. In this process parts of several specialized fields of physical science are used: impact mechanics, the deflagrate and detonation of explosives, and the behavior of materials under extremely high toads and rates of loading.Contents: Part I.
