The results of interior ballistic theoretical simulationindicates that the single PSS charge application need propellants be provided with upperburning rate, adopting PSS and traditional model frame propellants commix charge is apractical applied technique approach.. By optimizing the PSS model frame parameter, wecan obtain "flat roof" domino offect with better even peak value "double peak" p-tcurve. Comparing with current 19 hole propellants charge with the best increasing burningsurface characteristic, the muzzle velocity of projectile can be enhanced about 55m/s, andthe instruct pressure efficiency can be enhanced about 5.7％.

内弹道理论模拟结果表明，PSS发射药单一装药的应用，需要发射药具有较高的燃烧速度，采用PSS发射药与传统药型的混合装药，是目前PSS发射药实际应用的技术途径，通过药型参数的优化可获得"平台"效应更好的等峰值的"双峰型"P～t曲线，与现有增面性最好的19孔发射药装药相比，弹丸初速可提高55m／s左右，示压效率高5.7％左右。
