Abstract
A dual beam apparatus was developed which simultaneously
measured particle size (D32) at the entrance and exit of an
exhaust nozzle of a small solid propellant rocket motor. The
diameters were determined using measurements of dif fractiveiy
scattered laser power spectra. The apparatus was calibrated
by using spherical glass beads and aluminum oxide powder.
Measurements were successfully made at both locations. Because of the presence of char agglomerates in the exhaust, continued
effort is required to improve the grain design in
order to obtain consistent "across nozzle" data.
