Bullet impact tests for two solid rocket motors were performed and its results were compared and analyzed. One was loaded with the existing propellant with decreased weight content of burning rate catalyst and added high density additives to improve mechanical properties and the other was loaded with the existing propellant with decreased weight content of burning rate catalyst to improve its insensitivity as well as to maintain the ballistic performance. The composite cases were used for both motors.

Insensitive Munition(IM) reduces the explosive weakness of munitions, at the same time, maintains its performances in the moment of discharge, which improves safety of soldiers and minimizes unexpected accidents and casualties from being shot in case of transportation, storage and military operation. Development of IM has been focused as the global trend, which was required to satisfy the demand of army that is to minimize the loss of non-battle forces and to retain the competitiveness in export abroad. In this study, we categorize all the munitions used by ROK Army, then determine the priority of IM by deploying AHP(Analytic Hierarchy Process) method. In conclusion, we suggest the priority of IM which is suitable to the affairs of ROK Army.

N-Guanylurea dinitramide (GUDN) is an energetic material with low sensitivities and good performance for use as propellants or insensitive munitions explosives. The efficient synthesis and characterization of high energy density material of GUDN is reported. GUDN was characterized spectroscopically as well as elemental analysis. In addition, the heats of formation were calculated with the Gaussian 09 suite of programs. For initial safety testing, the impact sensitivity and the friction sensitivity were tested following BAM procedure.
