概述小型战术导弹加速用的双基固体推进剂发动机的特点是:燃烧压力很高、工作时间短、装药几何形状复杂;传统的方法是把许多根管形药柱联成一簇,这样试验测得的燃烧室压力与按紧密系数计算的值相距甚远。因此,问题就在于要建立一个考虑了不同推进剂起始温度 Summary The characteristics of small double-propellant solid-propellant engines used in accelerating small tactical missiles are: high combustion pressure, short working hours and complicated loading geometry; the traditional method is to combine many root-shaped pellets into a cluster, The measured pressure in the combustion chamber is far from the value calculated by the compactness factor. Therefore, the problem is to create a starting temperature that considers different propellants
