THE DETONATION PROCESS 



detonation wave for a 40/60 TNT/RDX mixture of density 1.5 from 

 adiabatics calculated by Jones. The experimental velocity U = 7,280 

 m./sec. was used, and the pressure, particle and sound velocities were 

 obtained as 177 kilobars, 5,660 m./sec. and 1,620 m./sec. The pressure,

although found to be initially 10 per cent lower than for TNT, fell less 

 rapidly to a final value of 44 kilobars, 10 per cent above that for TNT. 

 Although these results are the best available for the actual form of the 

 detonation front, no calculations of shock wave pressures from them 

 have been reported at the time of writing.
