Low Bypass Turbofan Jet Engine

thingiverse

A first study around a 50 Kg thrust engine model is presented, designed for assembly sequence, volume, and component layout analysis. The model, which will be displayed on a desk, will undergo a second design phase incorporating theoretical studies' outcomes. Some conceptual errors exist, such as bearing placement on hot components, approximate aerodynamic profiles, and missing combustion chamber and fuel injectors. Future revisions are planned. Key items for building the model include bearings, hardware, an LP fan, and tools like sandpaper, files, drill bits, and a hobby woodcraft lathe (optional). Printing settings vary based on item complexity. Assembly instructions involve cutting push rods to length and welding M3 nuts, while the external shell utilizes a modified ducted fan shroud with additional printed components. Printed parts require sanding, filing, and reaming for proper assembly, and a small lathe would aid this process. Completed model pictures along with assembly instructions will be shared soon.
