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％.
