摘　　要：建立了包含半可燃药筒燃烧以及其金属筒底剪断过程的某新型火炮的发射模型。利用Matlab编程进行了数值计算,验证了模型的可行性。分析了半可燃药筒金属筒底的厚度对发射性能的影响规律,确定了最佳剪断条件,且与同口径常规火炮进行了分析比较,结果表明该新型火炮能极大减小火药气体作用冲量,这对火炮武器系统具有重大意义。The launch model of a new type artillery is established, including buming of the semi-combustible cartridge case and shearing of its bottom. This paper carries out the numerical computation with MaUab, verifies the feasibility of the model and analyzes the influerced of the thickness of bottom of semi-combustible cartridge case on the launch property. Finally, the optimum cut condi- tion is determined according to it and the artillery is compared with same caliber conventional artillery. It is found that the artillery can reduce greatly propellant gas impulse, this performance is meaningful for weapon system.
