研究推进剂凝聚相反应宏观动力学的爆燃延迟法

The Method of the Deflagration Delayed Timefor Researching Macroscopic Dynamicsof the Condensing Phase of Propellant

介绍了一种用爆燃延迟期测定仪研究推进剂凝聚相高速分解反应动力学的方法。通过对硝化棉、双基和催化双基推进剂，以及ＲＤＸ等试样爆燃延迟期的测定，得出了爆燃延迟期与反应宏观动力学参数反应速度常数、活化能、频率因子以及燃速等之间的关系。该方法快速、简便、有效，且在充压条件下进行，更接近于推进剂实际燃烧过程。

A method for researching macroscopic dynamics of condensing phase of propellant by the defiagra-non delayed time measurement device is presented. The deflagration delayed times of nitro-cotton,doublebase and catalytical double base propellants and RDX specdriens are measured,then the relationships of thedeflagration decayed tine and reaction macroscopic parameters such as reaction rate constant, activation energy, frequency factor and burning rate are discussed.The method is easy to operation and because of the operation under a certain pressure so it is very close to the real combustion condition of propellants.
