EXTERIOR BALLISTIC TEST OF LARGE-CALIBRE MACHINE-GUN DUPLEX-AMMUNITION

摘要

In this paper, Multiple-station spark flash shadowgraph method and test results of large-caliber machine-gun duplex-ammunition(LCMGDA) are presented. On the basis of the distinguishing features of LCMGDA, experimental model and system are set up. Multiple-station spark flash shadowgraph method is employed to take self-disturbance, muzzle flow field and flight attitude of the two bullets of LCMGDA.. The experimental results show that the two bullets of the LCMGDA have been separated departing from the muzzle, their flight attitude is stabilized, and therefore it is proved that there isn 't mechanical disturbance each other between the two bullets departing from the muzzle.
