摘要
Abstract
Combustible case can produce some combustion ashes in the combustion performance experiment using closed bomb,and it doesn’t satisfy the implicit assumption that all propellant changes into gaseous product in the deduction process of this state equation,and the processing method for propellant force and covolme of combustible case were built based on this assumption. Aiming at this problem,a correction parameter related to the weight of combustible case ashes was introduced in order to obtain more accurate formula of propellant force and covolme to guide interior ballistic design for gun,and the processing method was corrected,and the formula of propellant force and covolume was derived.Aiming at closed-bomb experiment of some batch combustible case,propellant force and covolume were calculated using the corrected state-equation.Compared with the original processing method,correction quantity of force of propellant is smaller after considering the influence of burning ashes,but covolme is bigger.关键词
