美国已经制订了确定固体推进剂化学、物理和界面特性的标准性能表征程序。推进剂性能表征的目的是建立保证其安全性和工作参数的数据库,并更有效地改善推进剂的性能,减少对额外试验的要求。合格鉴定的意图则是验 The United States has established a standard performance characterization program that determines the chemical, physical and interface properties of solid propellants. The purpose of characterization of propellants is to establish a database that guarantees their safety and operating parameters and to improve propellant performance more effectively and to reduce the need for additional testing. The purpose of the qualification test is to test
