Investigation on spatial distribution characteristics of fragment damage field of composite warhead

Most of the threats faced by air combat units consist of clusters of lightly armored targets. Fragmentation warhead technology plays a crucial role in effectively engaging such targets. This study focuses on investigating the power performance and spatial distribution characteristics of the fragmentation damage field generated by multifunctional composite warheads, aiming to meet the damage requirements for these specific targets. The impact of falling speed on the fragmentation damage field is analyzed through a combination of theoretical analysis and numerical simulation. Furthermore, this research examines how the shape and arrangement of prefabricated fragments, as well as the angle at which they are deployed, influence the fragmentation damage field under varying falling speeds. Additionally, a method is proposed to characterize the spatial distribution characteristics of the damage field based on fragment distribution along a cylindrical surface surrounding the detonation point. These research findings can serve as valuable references for enhancing fragment effectiveness and improving warhead design.
