摘要:

本文对AP-CMDB和HMX-CMDB推进剂的燃速特性和燃烧机理进行全面的述评.虽然同属复合改性双基推进剂、且表面结构皆高度非均相,但气相燃烧波结构和燃烧机理及燃速特性都有很大差别.AP-CMDB推进剂燃烧的久保田模型已趋定型,而HMX-CMDB推进剂燃烧的久保田模型则在近年内已有了很大的改进.

Abstract:

An overall review on burning rate characteristics and combustion me-chanisms of AP and HMX-CMDB propellants is presented in this paper.Being composite modified double-base propellants and higly heterogeneous in surface structure,the-se propellants are different from each other in the combustion wave strutures of gas phase, combustion mechanisms and burning rate characteristics. The Kubota’s combustion model for AP-CMDB propellants has not be changed since 1976, but that for HMX-CMDB has been considerably impro ved recently.
