摘　　要：在文献1建立的RLPG集总参数内弹道学数学物理模型的基础上，对RLPG压力平台产生的条件进行了详细的探讨，推导了满足压力平台的喷孔面积与膛内其它参量之间的解析关系式，编制了计算程序，处理了计算过程中所产生的压力振荡问题，获得了工程设计中实用的产生压力平台的中心杆半径与其行程的变化关系曲线。On the basis of the lumped physical-mathematical model of interior ballistics given in reference 1,this paper gives a detailed discussion about the conditions leading to the formation of pressure plateau in the combustion chamber of a RLPG,and derives the analytical relationship between the jet area and other parameters under which the pressure plateau can be formed.A computer program is introduced in which the problem about pressure oscillation in calculation is solved.A curve for the radius of the central rod vs.its travel is obtained which is of practical use in the engineering design of a RLPG.
