M125 부스터 메카니즘의 해석 및 응용

M125 booster is one of the reliable S＆A device(safety and arming device) to determine the arming distance of fuze for gun ammunitions from 90 mm to 8 inch in diameter. And it is also well known that the arming distance of M125 booster is determined by the multiplication value of the gun tube property(traveled distance per turn of projectile) and the S＆A device property(number of turns to arm), not by the projectile muzzle velocity. We have tried and succeeded in executing a proper analysis on M125 booster to figure out its characteristic constant of arming distance by considering only the gun tube properties and the S＆A device properties. More detailed arming distance will be analyzed in the future by considering dynamic characteristics on all elements in the S＆A device with vector analysis.
