Development of the Continuous Wire Method

Abstract

This report covers the second period of development work on use of the continuous wire method to follow shock-todetonation transitions. It describes a successful method of producing satisfactory cast charges containing properly aligned wires. Methods of data reduction which have been developed are reported; they include as much automation as possible and have greatly reduced the data handling time. Detonation velocity measurements by the wire method on charges 15 cm long are accurate to within 0.5% (six shots). Values for cast Comp B and DINA are 7.97 and 7.72 mm/psec, respectively. The first objective of future work is improvement of synchronization in the electronic circuits.
