포탄에 묻혀있는 탐지코일에서 유도되는 전압으로부터 총구를 떠나는 포탄의 초기속도를 계산하기 위하여 링 형태의 자석, 요크 및 탐지코일로 모델을 구성하였다. 자기장 해석에 의해 탐지코일의 유도전압에서 구한 마스터 곡선으로부터 포탄의 초기속도를 구할 수 있다. 탐지코일의 유도전압은 포탄에 묻혀있는 탐지코일 직경의 크기에 영향을 받는데, 직경의 크기가 증가하면 유도전압도 비례하여 증가한다. 탐지코일에서 유도되는 전압의 직경 효과를 감안한 초기속도 변화에 대한 정보를 입력하면 목표에서 포탄이 정확하게 폭발할 수 있다.

This paper includes the comparative study between Cr plating and nitriding process with an aim at improving corrosion, wear and maintainability for KNR(Korean Next Generation Rifle) 5.56mm barrel. The endurance test was conducted to compare the performance of standard barrel, Cr plating barrel and nitriding barrel. Main activities are described as follows; optimal Cr plating and nitriding process set-up for KNR 5.56mm barrel; durability test of each barrel(20,000 rounds); salt water immersion test; dispersion, initial velocity, inner diameter data acquisition. According to the results of this firing test, Cr plating barrel is superior to standard barrel and nitriding barrel in view of corrosion, wear and maintainability
