Review of solid-propellant ignition studies

Experimental study of peat ignition upon exposure to radiant energy

“…This approach enhances the flammability index of an object. In the case of smoldering combustion, the minimum exposure time leading to steady peat combustion [12,13] was used as the delay time, and in the case of flaming combustion, the period from the start of exposure to the moment of flame oc- currence. The beginning of flaming combustion of peat was detected by the infrared imager.…”

Modeling of combustion and ignition of solid-propellant ingredients

“…A comprehensive review of the early work was conducted by Price et al in 1966 [181]. The experimental and theoretical literature pertaining to the ignition of solid propellants over the period of 1966 through 1980 was reviewed by Kulkarni et al [182] and Hermance [183]. The state of understanding in Russia up to 1989 was presented by Vilyunov and Zarko [184], giving a detailed examination of the various ignition models and related experimental approaches.…”

CuO/Al Igniters For Solid Rocket Motor Ignition

“…Both criteria stem from solid-phase ignition theories, in the terminology of Kulkarni, et al, 14 and thus gas phase heat release and mass diffusion effects are neglected. To establish the minimum energy required to build the thermal wave in the propellant to the necessary thickness for sustained combustion, a Michelson preheat profile for steady burning is assumed,…”
