It has a large region of application in solid rocket motor grain design and has made new improvements compared with other available codes . user can easily and rapidly build his initial grain shapes and then obtain geometric information of his design . according to the theory describeds in the paper , the regressions of the burning surface area and the pressure are obtainded
该系统扩展了固体火箭发动机装药的设计能力，用户可利用它简捷地构造出三维药柱的初始形状，并获得设计所需的各个几何参数，进而依据本论文提出的复杂三维药柱内腔燃烧推移和燃面计算的方法，计算出燃面变化和压强变化，得到推力随时间变化的曲线，再依据这些计算结果进行再设计，直至达到满意的结果为止。
