摘 要:采用最小自由能法计算了不同氧平衡发射药燃烧产物中可燃性气体成分的含量,用密闭爆发器-气相色谱法分析了燃烧产物成分,用高速摄影仪拍摄枪口焰,分析了枪口焰面积、直径、光密度等。结果表明,提高发射药的氧平衡,燃烧产物中可燃性气体成分含量降低,枪口焰面积、直径和光密度也降低。因此,提高发射药氧平衡,在一定条件下,可有效降低枪口焰现象。The combustible gas concentration in combustion products of propellant with different oxygen balance was calculated by using minimum free energy method. The combustible gas composition of the propellant concentration was analyzed by closed-bomb and gas chromatography. The photographs of muzzle flash were taken by high speed camera. The area ,diameter and photo density of muzzle flash on photographs were analyzed. The results show that with rising the propellant oxygen balance the combustible gas concentration and the area, the diameter and the photo density of muzzle flash are reduced. In particular condition, increasing oxygen balance of propellant can effectively reduce muzzle flash phenomena.
