The variable-burning rate gun propellant with glue and consolidation was manufactured with the grains of the variable-burning rate gun propellant as the base propellant and slightly managed with energetic glue to surface and firmly pressed. This charge has resolved the problem of progressive combustion of consolidation charge. The law of burning gas release of high charge density gun propellant was effectively controlled by combining the high charge density and progressive combustion performance of the variable-burning rate gun propellant. The combustion performance of base propellant and the variable-burning rate gun propellant with glue and consolidation were analyzed comparatively by the p-t and L-B curves from traditional closed bomb test. The results indicate that the variable-burning rate gun propellants with glue and consolidation kept high progressive burning of the variable-burning rate gun propellant and has high charge density and burning reappearance.
