Construction and Transmission Mechanism of Exterior Ballistics of High-Power Microwave Weapons

Booming technological advances and turbulent military reforms have promoted the continuous advancement of weapons and equipment. High-power microwave (HPM) weapons have changed the damage modes of traditional guns, missiles and other kinetic energy weapons, as well as having the huge advantage of "changing the rules of the game." The study of exterior ballistics of high-power microwave weapons has theoretical support for the design and development of weapons and the verification of performance indicators, and is also an important basis in the firing application of high-power microwave weapons. By studying the coupling mechanism between HPM weapons and targets, an exterior ballistics description of HPM weapons is given According to the description of exterior ballistics, the differences between HPM and traditional weapons in definitions, accuracies, space trajectories, space descriptions and "end points" are summarized and the exterior ballistics space transmission is established. This study reveals the nine major transmission laws of the exterior ballistics of HPM weapons. The constructed model and related theories of the transmission laws for exterior ballistics lay a theoretical foundation for the in-depth study of key technologies of HPM weapons, such as fire control and damage assessment.

Safe Conditions for Conducting Tests Using Ballistic Facilities

Understanding the physical and thermomechanical response of materials subjected to intense dynamic loading is a significant challenge that has a practical implication for modern engineering. Shock compression followed by expansion precipitates both reversible and irreversible physical and mechanical processes in the material. These processes include strong compression in solids, high heating rates, phase transformations, electronic structure change, work hardening, spalling. Methods and devices for producing intense shock loads can be subdivided into several groups. Presently, in worldwide practice, gun type launchers have gained the widest acceptance in studying dynamic compressibility, strength characteristics, and spallatation phenomena in laboratory conditions. In this type of facility, the launched body moves in a tube under the force of a compressed gas. The facilities differ depending on the gas used and the method of its compression. Specific features of the facilities impose certain limitations on the registration and format of the tests. Examples of determining the boundary between the interior and exterior ballistics, the influence of the launched body supporting elements and the conditions of safe testing at high-speed entry in fuel are considered in this work.

Experimental and Theoretical Aspects Regarding Design and Testing of Thermobaric Munitions for Recoilless Armament Systems

The purpose of this paper is to present theoretical and experimental aspects regarding the design and testing of a thermobaric unguided fin-stabilized reactive projectile destined to be fired from a recoilless smoothbore gun, namely the anti-tank grenade launcher SPG-9 (AG-9). Some theoretical aspects regarding thermobaric explosive mechanism are presented and experimental determinations are made considering the relation between the explosive core and the overall calibre of the munition. The interior and exterior ballistics of the munitions are estimated by mathematical models and the results are validated through experimental firings with the prototype munition. The destructive effect of the munition is estimated by real firings against buildings and structures
