Warheads
Software for warheads serves for design and performance analysis of warheads - high explosive fragmentation and shaped charge. The software was used and testing for several classical and rocket artillery projectiles and anti-tank weapons.

| Program name: | FragPred - Fragmentation Prediction |
| Version/Year: | Version 3.0, 2016. |
| Capability: | Calculation of number of fragments produced by the detonation of the high explosive (HE) warhead. Calculation of distributions, of fragment’s mass, linear and angular velocity in the polar zones surrounding the projectile. Prediction of parameters of the effective lethal area of naturally fragmenting warheads. Program has a clear GUI for entering and manipulating with data, and for controlling the execution. The results of calculation are printed in files and plotted on graphs. |
| Purpose: | Simple and fast, prediction of lethal area parameters with high reliability. Simulation of parameters that can be experimentally obtained from Arena and Pit tests. Powerful tool for weapon designers and warhead test. Computer program written specifically for naturally fragmenting warheads design and analysis. |
| Method: | A two dimension space, time dependent, fluid dynamic computer code. Metal casing is treated as sets of mass points of which motion is found along with the gas flow. The gas dynamics following detonation of the explosive is Lagrangian, with provision for slippage along the metal boundary. A conventional Lagrangian scheme with artificial viscosity is used for the interior gas dynamics. Gas grid points are made to slide along the metal boundary. |
| Origin: | Original development based on published literature and own experience. |
| Platform: | Windows XP, Vista, 7, 8, 8.1 and 10 |
| Required software: | None |

| Program name: | STINGER - Semi-empirical Shaped Charge Code |
| Version/Year: | Version 2.1, 2014. |
| Capability: | The STINGER is a computer code to address the shaped charge problem. The code accurately predicts jet-tip velocity and treats the buildup of the massive lead pellet for confined and unconfined charge Calculation of the pellet is accomplished in the code by including time dependent acceleration and material compressibility in the region of the liner near the apex of the conical liner. Comparison of the results from the code with experiments, as well as to more sophisticated hydrodynamic computer codes, showed good agreement. Program has a clear GUI for entering data, manipulating with data and controlling the execution. The results of calculation are printed in files and plotted on graphs. |
| Purpose: | Detail calculation of all parameters of shape charge jet and penetration process for constant and various depth of liner and calotte on the top of the cone liner. Analysis of the influence of various design parameters – liner geometry, initiation point, charge characteristics and others, on the jet penetrability, optimal standoff, jet diameter and deep of penetration in homogenous armor. |
| Method: | Combined, empirical and potential method (semi-empirical) based on huge data base collected from published data from western and eastern countries and own experience. |
