fast-aircraft-design/fast-oad — reverse-engineered prompt

Build me an open source Python framework for rapid overall aircraft design studies. I want something researchers and engineers can use to size and compare aircraft concepts quickly, run multidisciplinary analysis and optimization, and easily switch between different models for the same discipline depending on the study.

Please make it modular and plugin based, so separate add ons can provide models for things like commercial transport aircraft, regional aircraft, general aviation, hybrid or electric concepts, and UAV style designs. It should also be easy for someone to plug in their own custom models later without changing the core framework.

I’d like both a simple command line workflow and a clean Python API. Include good documentation, example tutorials in notebooks, and tests, so people can try it quickly in Jupyter or install it locally on modern Python, around 3.10 and up. Use OpenMDAO underneath for the analysis and optimization pieces. If you need specifics, look up the current docs online and make it feel polished and practical.
