The current research situation of static burning rate,dynamic burning rate and measurement technology of burning rate under specific environment for solid propellant,and characteristics of various burning rate measure-ment methods were reviewed.Considering that the general development rule of solid propellant burning rate meas-urement technology is that from the static burning rate measurement gradually developed into the dynamic burning rate measurement.On the basis of the dynamic burning rate measurement,the rotating overload burning rate meas-urement technology and burning rate measurement technology under the transient pressure condition appeared.The existing burning rate measurement technology is also used to test the combustion performance of commonly used high-energy additives in solid propellant.The future development direction of the combustion performance testing technology of solid propellant,including high pressure （ultra pressure）combustion performance measurement tech-nology,ultra low pressure （vacuum,）combustion performance measurement technology and low temperature micro-gravity combustion performance measurement technology etc,is pointed out with 55 references.
