摘要
推进剂燃烧环境中金属颗粒的结团现象对固体火箭发动机性能有重大影响.本文对双基推进剂结团的表面反应层模型及复合推进剂结团的口袋模型进行了述评.鉴于实验中发现的某些燃速和压强效应的异常,本文还对新近提出的亚口袋机理和口袋间机理进行了述评.
The agglomeration phenomena of metal particles in propellant combustion enviroments have great effects on the performance of solid rocket motors. On the basis of general description of agglomeration phenomena some reviews on surface reaction layer model for DB propellant agglomeration and on pocket models for composite propellant agglomeration are presented in this paper. In view of some anomalies on effects of burning rate and pressure, some reviews on'sub-pocket'mechanism and'inter-pocket'mechanism recently are also discussed.
