摘　　要：在分析前置式膨胀波火炮后喷装置结构的基础上,建立ZBL-09式122mm自行火炮前置式后喷装置的简化模型;喷管间距不同时,应用FLUENT软件对影响反后坐效能的后喷装置入口与身管法线的连接角度进行计算分析,得到最佳连接角度与喷管间距的关系,最佳连接角度随喷管间距的增加而增大。Based on the analysis of back blast mechanism for rarefaction wave gun, a sim- plified model of ZBL-09-type 122mm selfpropelled gun is established. In the case that noz- zle spaces are different, with the help of FLUENT, the angle between the inlet of back spray structure and the barrel＇s normal is measured and analyzed, and the relationship between op- timized angle and nozzle spacing is achieved. The result shows that the optimized angle should increase with nozzle space increasing.
