| 摘 要： | 从理论上研究了硝酸铵对发射药燃烧产物组成的影响;采用高速摄影仪进行炮口焰拍摄,采用炮口焰面积、炮口焰最大直径、积分光密度对炮口焰进行表征.研究结果表明:在发射药中加入硝酸铵,可以明显降低燃烧产物中可燃气体含量,减小炮口焰;配方中,硝酸铵含量为70%时,与单基药相比,可燃性气体含量降低了98.4%.混装发射药中硝酸铵含量达到25%时,与制式药相比,炮口焰面积减小了44.7%,最大直径减小了31.4%,积分光密度减小了44.7%.

| Abstract: | The impact of different ammonium nitrate content on combustion products of the propellant was studied theoretically.The photographs of muzzle flash were taken by high speed camera.The area,the maximum diameter and the integral optical density of the photographs were used to characterize the muzzle flash.The experimental results show that adding ammonium nitrate in gun propellant,the combustible gas content is reduced and the characters of muzzle flash is lower than that of reference propellant.The ammonium ... |
