3. observed for propellants. Such a flat-flame burner has also been used at ONERA (Fig. 17) and the temperature profile has been matched to that obtained from Eq. (25)for the conservation of energy, confirming the low activation energy of the reaction, Egi = 5-7 kcal/mole. Such a procedure has also been applied to the temperature profiles obtained by Kubota^6 (Fig. 18) on propellants in such a way that an estimate of the effective kinetics of the primary flame can be obtained, again with Egi - 5 kcal/mole. Therefore, it appears quite likely that the primary flame of double-base propellants is due principally to N02/aldehyde reactions.
