Chapman-Jouguet pressure:

A linear relationship between Chapman-Jouguet pressure and density was confirmed for Cyclotol and Octol (Ref 28). Despite the near-equal performance of RDX and HMX at equal densities there appears to be no economical way of making the density of RDX equal to the cast density of HMX. Dinitrobenzene (DNB) has been evaluated as an economical or emergency substitute for TNT but charges prepared with DNB gave somewhat poorer performance than... [Pg.415]

Pressure, Detonation. Detonating condensed expls develop very-high pressures. For most military expls and many of the commercial expls the pressures attained within the expl column do not depend on confinement, provided the column diameter is appreciably larger than the critical diameter of the expl. This confinement-independent pressure associated with a steady detonation is called the Chapman-Jouguet pressure or PCJ... [Pg.844]

Dremin Shvedov (Ref 3) measured by an electromagnet method the CJ pressure time of reaction in detonation waves of RDX, TNT, PETN, Tetryl, DINA, and of some of their mixts.

Detonation, Shock Pressure in and Its Measurements. A brief definition of shock pressure is given under Detonation, Shock, Shock Effect, etc. Besides shock pressure, known also as spike pressure, there is also the pressure at the end of the reaction zone (See Detonation, Reaction Zone in). The latter pressure is known as Chapman-Jouguet Pressure or C-J Detonation. It is explained under "Detonation, Chapman-Jouguet Parameters and also under "Detonation (and... [Pg.519]

The Aziz et al theory appears to be less successful in matching exptl data than the Gurney theory, except at m/c < 0.1. For m/c < 0.3, the Aziz curve for T = 3.16 is good fit for the exptl data. For m/c 1, T must be decreased to 3 to obtain a fit, and at m/c of about 2 it appears that T must be slightly less than 3. Thus the Aziz et al approach requires a variable T to fit exptl data. What is even more disturbing is that these T s (0 < m/c < 2) are all appreciably larger than the T s obtained from Chapman-Jouguet pressure measurements (Table 6)... [Pg.211]
