INFLUENCE OF GAS PHASE REACTION ON THE BURNING BEHAVIOUR OF PROPELLATNS -AN ANALYTICAL AND NUMERICAL STUDY A simple analytical study of heat and mass transfer interaction between condensed and gaseous reaction zones of propellants suggest that the pressure exponent of a burning propellant is the half value of the order of a one step reaction kinetics in the gas phase. A comparison with calculations of a comprehensive numerical model confirms this widely. Additionally the influence of the Arrhenius parameters of the gas phase reaction on the burning behaviour of the propellant is discussed.
