Og. Glotov, Condensed combustion products of aluminized propellants. II. Evolution of particles with distance from the burning surface, COMB EXPL R, 36(4), 2000, pp. 476-487
Condensed combustion products of a model propellant on the basis of ammoniu
m perchlorate and aluminum were studied using the sampling technique. The g
ranulometric composition of combustion products and the content of metal al
uminum in particles of size from 1.2 mum to maximum were determined within
the pressure range of 0.6-7.5 MPa at a distance from the burning surface up
to 190 mm. A multimode structure of mass distributions of oxide particles
within the size range of 1.2-40 mum was found. An empirical dependence of b
urnout of metal aluminum from agglomerates on the residence time of particl
es in the plume of combustion products of the propellant sample was obtaine
