For solving timely ignition of travelling charge and regular energy releasing, a new mode of travelling charge has been proposed. Propellant is substrate propellant, adopt existing energetic binder, use the energetic binder with lower burning rate and energy by compaction technology to shrink and wrap the propellant with higher burning rate and energy, press it into travelling charge cylindrical grain with high density and high strength, and achieve the purpose of controlling energy releasing control of travelling charge. Clad the end of the cylindrical grain with newly developed slow-burning material, combine cylindrical grain's compactness, and achieve the timely ignition of travelling charge. And research it through closed-vessel experiments, the results show that combine the cylindrical grain's compactness, travelling charge timely ignition can achieve by slow-burning layer; the whole combustion performance of travelling charge is stable, repeatability is good, it has good macro properties of progressive combustion and energy release rule.
