Abstract

Abstract

In order to study the influence of the spoiler on the overturning angular velocity of the ammunition in the dispensing process, the central-gas dispersing interior ballistic process was modeled and simulated by a two-dimensional, two-phase flow model. The comparison between the numerical simulation results and the test results proved that the above model was feasible. The comparative analysis of the flow field structure and the ejector stress states shows that the turning torque of the ejector can be enhanced by elevating the spoiler when the holes of the gas generator are on the top of the spoiler. And the final result can provide a theoretical basis to improve the submunition dispersing system.
