The major technique of an air-defense warhead is to improve the damage after effect. Therefore, a new Kinetic Energy Rod (KER) warhead named profiled rod warhead is proposed in this paper. The detonation process is simulated by ANSYS/LS-DYNA, and the deployment velocity and initial flight attitude of rod are achieved. Rigid body dynamics equations of rod, which accounts for the influence of air resistance, are set up to predict the flight trajectory of long-distance. The results show that profiled rods are conducted to determine a higher penetrability compared with traditional cylindrical rods, and the profiled rods may provide a better penetration angle that still maintains a significant penetrability against projectiles when the rods move off long-distance range.
Introducing an gasbag made of novel textile reinforced composite, investigating the tensile properties of this composite through comparison with different directions and speeds tensile test. The research indicates that this composite has preferable tensile properties, and the tensile properties are the same between transverse and longitudinal direction. The tensile fracture is brittle fracture. This result supplies necessary base for application of this new type textile reinforced composite.
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.
