Abstract

The history and the actualities of developing earth-penetrating weapon are described. The fighting assemblies with penetrator have been applied in accurate guided weapons widely. The technical difficulties for developing low-yield earth-penetrating nuclear weapons have not been primary obstacle. The experimental technique of gas gun and its applications in earth-penetrating weapon tests are introduced. The experimental results indicate that there is a favorable analogical relation among earth-penetrating events, but there are many essential differences between penetrating phenomena of concrete and of granite. A method for calculating profiles on acceleration, velocity and displacement of penetrating projectile upon penetrating depth data is introduced.
