【Abstract】 The modular propelling charge system is a new subject for propellant charge. It is important and crucial for its development to research performance of modular propelling charge system.In order to investigate its performance, in this paper, the combustion performance, ignition and flame-spreading ability, charging construction, ballistic behavior, insensitivity, operation performance and processability of Modular Charge A in double modular propelling charge system were studied by applying the combustion theory, the ignition and flame-spreading simulation tehnique of propellant, the charging technique, the interior and exterior ballistic theory, LOVA techique and operation and manufacturing process of modular charge.etc. on the basis of propellant charge theory. Other investigations were also conducted,such as effect of erosive burning of propellant on combustion performance of low number of modular charge, the design way of combustible container matching with propellant burning, the effect of different igniting power and different flame-spreading construction on igniting and fame-spreading performance of modular charge, the effect of charge structure on the performance of modular charge, the design way and sheme to meet interior and exterior ballistic requirements of modular charge, insensitivity condition and operation performance of modular charge, the process technology to autoassemble modular charge. The result shows that:The bore pressure of different numbers of modular charge can be changed to a certain extent,and the bore pressure of less number of modular charge increased, by employing erosive burning rule of propellant.It can be quantitatively determined if the content of nitrocellulose in a combustible container matches with the amount of propellant in modular charge burning completely, according to its amount of strong oxizing radical in reaction of its strong oxizing radical, strong reducing radical and free radical with cushioning effect on modular charge burning.Full identical and non-directional requirement and unstable pressure condition of unit modular charge can be solved by researching ignition structure of central black power according to symmetry and strong heat spreading principle.The structure designs of modular charge for different use can be accomplished by adopting non-directional design, minimum amount principle and balance technique, inserting and non-inserting structure techique.Ballistic design of modular charge was finished by applying its comprehensive optimization method and recurrence program according to the interior and exterior ballistic principle.LOVA and operation performance of modular charge were explored so as to find out a way to improve its insensitivity and operation performance through 12M drop test, quick cook-off test, bullet impact test, impact test of cavity charge jet, road transportation test,rain test and high temperature and humidity test.The process and key techique for autofilling modular charge were explored by analyzing its assembly process.The performance of modular charge was studied so as to find out the rule affecting its performance and set forth a way to solve the problem in its performance to develop it.更多还原
