Tiger computer code

The diazido compd can be detond by friction. It has an expl temp of 165° a Qc of 825.4 (avg) kcal/mole a Qf of 78.9kcal/mole and an impact sensy of 5.7cm using a 2kg wt and an Aberdeen Impact app with No 12 tools (vs 26.7cm for PETN). Theoretical calcns using the TIGER computer code detdthe flame temp (3120°K), force (4.46 inch-lbs/b) and chamber press (39800 psi) of M-2 proplnt when the drazide was substituted for NG in the formulation, (19.34%).

Other versions of the BKW code were written in the 1960 s and 1970 s. Cheret of the French Commission of Atomic Energy wrote a code called Arpege in the 1960 s. The Lawrence Livermore code RUBY was replaced by a code called TIGERS written by scientists at the Stanford Research Institute. It has been used extensively by various U.S.A. military laboratory scientists. Except for coding details, the various computer codes were essentially equivalent. The parameters of the BKW equation of state have been recalibrated by various groups of scientists for use with their particular types of explosives. Many of the parameter sets reproduce the performance of particular explosives, but do not reproduce the shock Hugoniots of the detonation products. 

P) A new digital program for the IBM 360 Computer, named STARFIT, has facilitated the extension of TIGER CODE calculations... 

There now are various different codes available for computing detonation parameters (e.g. TIGER, CHEETAH, EXPL05 etc.). In this discussion, we will concentrate...
