A new method of measuring the burning rate of as-manufactured grains of nitrocellulose-based propellants was developed. Chamber pressurization to 50,000 psi (3400 atm) was achieved using a hydraulic pump, rather than a nitrogen intensifier system; the burning interval was monitored by recording the acoustic emission from the burning propellant. Burning rate variations of nitrocellulose-based propellants (M1 and M26), burning at pressures between 10,000 and 40,000 psi, were recognized by examining the level of the combustion-generated acoustic emissions.
