Radiative ignition of double-base propellants. I - Some formulation effects

Experimental study of peat ignition upon exposure to radiant energy

“…Depending on the mode of peat ignition (smoldering or flaming), the ignition time was determined by the yes/no criterion [11] or the occurrence of flame. In this work, in contrast to the yes/no criterion from [11], as the ignition time we used the minimum exposure time of the radiation flux that led to the development of combustion in at least one case; i.e., after the cessation of irradiation, the sample was observed for 20 min, and if peat combustion continued, it was considered that peat ignition occurred.…”

Nonlinear Burning Stability of Solid Propellants.

“…No criterion whatsoever is found in the literature for the case of dynamic extinction by fast deradiation reported by the Princeton group (Refs. [38][39][40]. As to the low pressure extinction (or PDL extinction), a large amount of experimental and theoretical work was performed on pure AP deflagration but without conclusive results; less work appears to have been done on AP-based composite propellants and even less on other propellants.…”

“…This line of research was motivated by experimental results, on dynamic extinction by fast deradiation collected by the senior author during his stay at Princeton University (Refs. 12,[38][39][40]. An original theoretical approach of nonlinear burning stability of solid propellants was hence developed (Refs.…”

“…(ii) §ame retention, or the ability of the propellant to self-sustain upon removal of the external heat §ux; and (iii) §ame spreading, or the ability for propellant adjacent to the ignition site to become ignited [3].…”
