Characteristics of the products of combustion of metallized
solid propellant strands at pressures between 250 and
750 psi were investigated using holography and light scattering
measurements. In addition, scanning electron microscope
and light scattering measurements were used to examine
guenched residue. A reduced smoke ZrC propellant and three
propellants of varying aluminum loading (2%, 4.8%, and 16%)
were examined. The objective of the experiments was to
provide sufficient particle data from strand burners to make
it possible to determine if any correlation of results from
this method of analysis could be made with results from
other more complex solid propellant motor measurements, such
as plume probe and signature measurements. The results
of these efforts reflected the inability of any single
technigue of analysis to completely describe particle
size distributions. These results also suggest the need
for modificaton of current experimental apparatus and
procedures.
