• Weapon Systems, Semester 2, position 3

The main objective of the course is that students understand the importance, the basic concepts and methods of projectile design as an integral part of the science of weapons systems. Students should understand the key ideas about the types and purpose of projectiles, safety in the use and mechanisms of action.

Student gets contemporary knowledge about the main types of projectiles (high-explosive, armor-piercing, special) and the basics of their design. Student could use methods of calculation of different types of projectiles and their components.

1. Introduction to the projectile design. Basics of projectile safety during the movement in the gun barrel. Stress of projectile elements in the gun barrel. 2. High-explosive projectiles. Fragmentation warhead. Number, individual mass and shape of fragments. Configuration and direction of the fragments beam. Fragments' ballistics. Efficiency and specific efficiency of fragmentation warhead. Blast effect. 3. Shaped charge projectiles. Theoretical basis for a shaped charge effect. Hydrodynamic theory. Misznay-Shardin's effect. 4. Armor-piercing projectiles. The influence of the mechanical characteristics of the projectile and armor on the penetration process. 5. Special purpose projectiles. Design characteristics of special-purpose projectiles. Smoke projectiles. Illuminating projectiles. Incendiary projectiles. Aerosol projectiles.
