The OpenEaagles Project is an open-source simulation framework that supports the development and integration of simulation systems, particularly designed for applications in research, training, and testing in environments such as aviation. This project aims to provide a comprehensive toolset for building complex, multi-domain simulation systems, incorporating features like real-time graphics, networking, and hardware interfacing.Primarily written in C++, OpenEaagles offers a modular architecture allowing users to assemble custom simulation models tailored for specific requirements. The framework facilitates the simulation of interactive and non-interactive systems which can be used to evaluate human performance, system survivability, and operational effectiveness.Originally developed by personnel at the U.S. Navy's Naval Air Warfare Center Training Systems Division and later maintained by an active community of developers, OpenEaagles provides a robust foundation for anyone looking to develop or enhance simulation capabilities.
