钝感火药和混合装药定容燃烧性能的评定方法

Evaluating Methods of Combustion Performance at Constant Volume of Deterred Propellant and Mixed Charge

密闭爆发器试验是目前评定火药定容燃烧性能最主要的方法。通过密闭爆发器装置直接测量的ｐ—ｔ曲线经数学处理得到的各种参数关系，其基本条件是均质火药和平行层燃烧规律。但对混合装药或表面经钝感处理的火药，这种传统的处理方法有一定的局限性。该文分析了产生这种局限性的原因，提出了适用于钝感火药和混合装药的定容燃烧性能评定方法。

Propellant’s combustion performance at constant volume accessed by closed bomb test is the most universal method of today.The relationships between parameters received from mathematically treated p t curve measured directly from closed bomb device are based on homogeneous propellant and parallel combustion law.But for mixed charge and deterred propellant,this traditional method has some limitations.In this paper,the reason causing the limitations is analysed and evaluating methods fit for deterred propellant and mixed charge’s combustion performance at constant volume are advanced.Application of all evaluating methods is discussed.
