During the field operation of the Korean MBT(Main Battle Tank), the multi-smoke projectile launching system failed to function. As a result of conducting analysis, it was confirm that the gear shaft of reducer was failed. Therefore, a study on improvement in impact resistance of the reducer was conducted. The reducer was improved impact resistance by changing the design and material of gear shaft. The reliability of modified reducer was investigated by finite element analysis, performance and environmental tests. As a result of analysis, a strength of the modified gear shaft was improved by about 20 times than before improvement. The results of performance and environmental test show that the modified reducer is applicable for Korean MBT under the severe conditions. The quality improvement of multi-smoke projectile launching system contributes to survivability of Korean MBT.
