含CL-20改性双基推进剂的燃烧性能

摘要

The formulation of composite modified double base (CMDB) propellant containing different content of hexaazaisowurtzitane( CL-20) or RDX was designed. The effects of the CL-20 or RDX content on combustion properties of two groups CMDB propellants were studied. The results show that the burning rate of CMDB propellant containing CL-20 in the pressure range of 2-20MPa is higher than that of CMDB propellant containing RDX. The pressure exponent of CMDB propellant containing CL-20 increases with the increase in the content of CL-20. Some catalysts lead salts, copper salts and carbon black used at present can adjust the combustion characteristics of the propellants containing CL-20.%设计了两组不同含量CL-20或RDX改性双基(CMDB)推进剂配方,研究了CL-20或RDX含量对两组CMDB推进剂燃烧性能的影响.结果表明,在2～20 MPa,CL-20改性双基推进剂的燃速高于RDX改性双基推进剂的.CL-20含量越高,CMDB推进剂压强指数变大.现有的铅、铜盐和炭黑催化剂可用于调节含CL-20改性双基推进剂的燃烧性能.
