【Abstract】 In this paper,a combustion model put forward resently for the multibase propellants is introduced.Based on its numerical method,the influence of propellant chemical composition,including main components and their proportions,on the burning characteristics is studied;the theoretic analyses on the mechanisms of the transfer in the burning rate versus pressure curve and that pressure index is more than 1.0 of the nitramine propellants in certain pressure region are carried on in the view of chemical structure and chemical reaction,and some basic principles of optimization and designation of multibase propellant burning characteristics are proposed.更多还原
