Definition: Emplanes is a software development framework developed by Airbus Defence and Space. It is designed to enable rapid prototyping of complex systems, including spacecrafts, drones, and unmanned aerial vehicles (UAVs). Emplanes allows for the creation of reusable models without needing expensive prototypes or expensive equipment. The framework was originally developed as a tool for engineers and scientists working on large-scale projects, but it has since been adopted by many other industries to help with development and testing of complex systems.
