A new design of shaped charges with a complex cumulative casing was proposed. The casing consists of two parts: conical and spherical. Mathematical modeling is conducted to determine the optimum shape of the cumulative casing. The feasibility of increasing the inlet area formed at detonation of the proposed shaped charge up to 2.8 times has been demonstrated.
The paper proposes the new technique of manufacturing the elongated cumulative charges (ECC); the technique was developed to advance the ECC efficiency and to reduce the production costs through lowering their manufacturing cost.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
