Abstract:
T w o methods of measuring the velocity of f lying sho ts and the measur ed result s have been discussed in this paper . One is the hig h-v elo city photogr am for measuring the velocit ies o f the shot s at near the muzzle. T he results show ed that the average velocity of the sho t s is about 480 m/ s, the radial spreading velocity of the shot s about 49 m/ s, and the t raverse spreading velocity abo ut 30 m/ s. The other is the sy stem of segmented aluminium fo il targ et for measuring the sing le shot f lying velocity at a dif ferent r ange and the result s show ed that on an average, the velocity is about 361 m/ s at r ange 20 meters, 307 m/ s at rang e 30 meter s and 257 m/ s at range 40 meters. The reduct ion of the velocity decr ease is about 16 % due to the four-layer foil.
