摘要
Abstract
The combustion model of multi-perforated disk(MPD)gun propellant was established to simulate and improve its combustion behaviors.Under the precondition of the geometry combustion law,the calculations describing pressure history and dynamic vivacity relationship of MPD were carried out.Influencing factors such as disk thickness,perforation diameter,burning rate coefficient and exponent were analysed.The results showed that the geometry and formulation influenced the burning char-acteristics of MPD.The maximum dynamic vivacity and burning time increase with the increase of disk thickness and the de-crease of perforation diameter.But the influence of MPD geometry has lower impact on the combustion behavior.Compara-tively,the burning coefficient and pressure exponent influence the burning behavior most,and the best propellant formulation should possess higher coefficient and pressure exponent.关键词
