Combustion of ammonium perchlorate-polymer sandwiches

“…the protrsboundary of the crystal phase change layer sion is dramatic (10 MP*) 110, II, 151.

Prediction of Particle Size of Ammonium Perchlorate during Pulverisation

“…The burn rate, in SHORT COMMUNICATION turn depends upon particle characteristics of the oxidiser, metal fuel, and burn rate catalyst [3][4][5][6] . The coarse/fine combination of ammonium perchlorate affects the burn rate more prominently than the other ingredients used in composite propellants.…”

Computational Fluid Dynamics in Combustion

“…There are other additives in the propellant; but these are not considered at present. To understand the behaviour better, a two-dimensional analogue of the propellant has been experimentally investigated in the literature 19,20 . A schematic of this is shown in Fig.…”
