ABSTRACT

The ignition characterization of a natramine minimum smoke HMX/AP/PPE propellant and an AP/HTPB propellant have been analyzed experimentally by a CO2 laser generator and a Kodak Ektapro motion analysis workstation in this paper. Experiment results show that the ignition delay time, initial ignition flame structure and the steady combustion flame structure of the minimum smoke propellant are quite different from those of the AP/HTPB propellant. The results also indicate that the increasing of heat flux or ambient pressure lowered the ignition delay time.
