英文摘要：

The small caliber combustion and propulsion device of bulk-loaded liquid propellant was designed. Using stepped-wall chamber, the problem of combustion stability of bulk liquid propellant has been studied. The results show that the consistency of p- t curves and the stability of combustion are better by means of 3-step-chamber. Based on above experiments, a simplified mathematic model of interior ballistic of bulk-loaded liquid propellant gun has been developed. The numerical simulation is well matched with the experimental results.
