Abstract:
Serial double-chamber gun is a new-type laucher. It can increase the project ile muzzle velocity, but the maximum pressure is not too high. This has prosperous applicat ions in improving present guns. In this paper, a classical model of serial double-chamber is established and numerical simulation is conducted. The ef fects of dif ferent factors on interior ballist ics are discussed. T he calculat ion result s indicate: ( 1) The effect s of charge ratio on muzzle velocity are too big, but it has a best value. ( 2) If the ignit ion delay is too big, the propellants canÄt be burnt ; if the ignit ion is too small, the improvement effects are small. ( 3) The variat ion of muzzle veloc-i ty with piston weig ht is increased f irst , and then decreased. At last , the development direct ions and applicat ion prospects are also analysed.
