tomaspfontes/RotorcraftDesignTool — reverse-engineered prompt

Build me a Matlab app for early stage rotorcraft design. I want something a student or engineer can open and use to explore helicopter and drone concepts, enter basic mission and vehicle assumptions, and get first pass design estimates with simple charts or visuals.

Keep it focused on preliminary design, not detailed simulation. The app should feel like a real thesis project tool, clean enough to demo, with clear inputs, readable outputs, sensible defaults, and room to expand later since this is still a work in progress. If there are PDFs or notes in the repo, please use them to shape the workflow, equations, and terminology so it matches the original academic intent as closely as possible.

Please wire up both the interface and the calculations so it actually runs, and include at least one example case people can load to see how it works. If you need anything missing, check current Matlab App Designer docs online and make practical choices that fit this kind of design tool.
