An optimized C library for numerically solving exterior ballistics problems. It supports standard drag models (Drag Functions G1-G8). The solution method is the common "3 degree of freedom" analysis found in many commercial programs.
Arrowmatcher is a ballistics software for crossbow archers. It can calculate the speed, kinetic energy, trajectory, aiming solution and much more of an arrow (or bullet). It uses a simplified 6 degree of freedom model.
pyBallistics is a graphical small arms ballistics program used to calculate ballistic coefficients, and model bullet trajectories. Future improvements will be a reloading database, and web links to industry reloading data.
A graphical interface for solving exterior ballistics problems, based on the excellent GNU exterior ballistics library. This software generates valid 3-DOF solutions to small arms trajectories, including wind and atmospheric corrections.
chamber is a reactive hydrodynamic modeling tool specifically designed for small arms interior ballistics research. Multiple equations of state and burn models are supported. chamber is an adaptation of the BKW, SIN, 2DL and 2DE codes in one package.
