The internal ballistic process and flow field were examined in the context of the launch of hydrogen-oxygen bipropellant explosives. This was achieved through the establishment of an internal ballistic launch model, which employed the high-low pressure launch principle. This approach diverges from the conventional tenets of internal ballistic theory, wherein a combustible gas is employed in lieu of a propellant for the purpose of launch. Furthermore, a high-low pressure chamber scheme was devised with the objective of mitigating the overload peaks that are typically encountered during the launch process. A fluid simulation was employed to conduct a virtual analysis of the flow field alterations within the high-low pressure chamber during the launch of a hydrogen-oxygen bipropellant explosive utilizing the internal ballistic model. The pressure variations over time within the high-low pressure chambers throughout the launch process were investigated, and the results were supplemented with load motion and physical ejection experiments. The results demonstrated that the simulated and calculated curves exhibited slight elevation relative to the real curve under identical conditions, yet remained within an acceptable range of error. Our study successfully validated the feasibility of utilizing hydrogen-oxygen combustion launch schemes for small load ejection, offering a valuable reference point for future research and optimization in this domain.
