Temperature sensitivity of solid propellant burning rate.

Burning Phenomena of the Gun Propellant JA2

“…Formulas like Eq. (2) were derived for ablating surfaces when exposed to heat transfer (25,26) and were discussed by Glick (9) , Ewing and Osborn (10) for rocket propellants to describe the dependence on initial temperature. Crow and Grimshow proposed a similar law for gun propellants (27) although the parameters were of different meaning.…”

“…Simpli®ed approaches of models were used to investigate the temperature sensitivity or the response to the radiation on ignition and on radiation assisted combustion (7,9,10) . The temperature insensitivity effect is frequently used in the case of doublebase rocket propellants.…”

Effect of Initial Temperature and Pressure on the Burning Rate of AGAT/AN Mixtures

“…Theoretical studies have been carried out over the years on the mechanisms regarding temperature sensitivity [2][3][4]. According to Kubota and Ishihara [2], temperature sensitivity could be divided into temperature sensitivity of gas-phase reactions and temperature sensitivity of condensed-phase reactions, and these can be examined if gas-phase and condensed-phase reactions are understood in detail.…”

“…Factors that affect the burning rate of the propellants are pressure and temperature, and there has been much research on the effect of initial temperature on the burning rate of rocket propellants [1][2][3][4][5][6][7][8][9] but there does not seem to be such research related to air bag gas-generating agents.…”

The burning mechanism of ammonium perchlorate- based composite solidpropellants

“…Of obvious practical interest is also the response of a solid propellant to high initial temperature conditions (187); at present, the rocket engineer must still rely on empirical .74-data concerning the effect of this parameter. The prediction of burning rate as a function of initial temperature is the natural outcome of any theory of propellant burning.…”
