TNT , 50% fine 50% coarse (-6+8 mesh) of density 1.12 and chge diam 4.8 mm, initiated with "Knotted Primacord" had initial vel of 2070 at the distance from initiator of 5.0 cm, then at the distance of 7.4 cm the vel was 3190 and after this a stable regime was established with vel 5150m/sec. The three-regime transient phenomena are also illustrated by framing-camera results for cast TNT shown in Fig 3.13, p 55. Here... 

ZePdovich Kompaneets (I960), p 217 stated that in the case of condensed expls (such as NG, cast TNT, etc) it can be assumed that the. reaction mechanism does not differ essentially from that in gaseous... 

Detonation Transients and Unstable Detonation Processes. Allen et al (Ref 1) made detonation velocity vs chge length. measurements on RDX (—65+100 mesh), fine grained TNT (—35 —150) coarse, low-density TNT (—8+10) 50/50 fine-coarse TNT, cast TNT, low-density. mixts of 80/20 TNT/AN, and mixts of 90/10 AN/RDX. Deton velocities were measured by a rotating mirror streak camera and by the pin oscillograph technique, in most cases simultaneously Their exptl data showed six different types of velocity transients ... 

Dual discontinuous transitions from constant or nearly constant velocity regimes. This type of transient was observed in cast TNT, fine grained TNT, and in coarse grained TNT (not previously observed)... 

Similar but somewhat complicated tran-s ient phenomena) have been observed by Allen, Cook and Pack (Ref 44b) in fine-, grained, loose TNT mixture of fine and coarse loose TNT and in cast TNT. 

Ir is operated as a fixed mount, but is strategically mobile when the gun tube is retracted, and the carriage is loaded on heavy artillery transport T10. The,projectile made of a one-piece steel forging is the "deep cavity" type and contains 101.7 lb of cast TNT and a... 

For pure primary secondary explosives (except for border-line HE such as Ammonium Nitrate or Ammonium Perchlorate) dcr decreases as p0 increases until p0 approaches very close single crystal density when dcr may increase drastically. Thus if we limit ourselves to p0 < 0.9pcrySt, increases in p0 (according to Eq 8) should result in a greater sensitivity to impact. This is quite the opposite of what is found for shock initiation and will be examined more closely later on. At a fixed density, dcr increases as p. increases (see A B, p 90). This increase is fairly pronounced at small p (<0.2 mm) but levels off becomes almost asymptotic at large p (>0.4mm, except for cast TNT or TNT with 1% paraffin oil). Thus an increase in p, as expected, leads to a decrease... 

Granular TNT is used as the bursting chge of hand grenades, mortar shells and in mines. Cast TNT is used as a bursting charge in some bombs,... 

Type 94 37-mm HE Ammo had the proplnt as above and the forward 1 /3 of the proj cavity filled with PA, while the after 2/3 of the cavity filled with cast TNT. Used in all 37-mm Guns (p 295)...
