High Bypass Engine Nacelle

Now incorporates Revision 2 of the 3D printable engine from CATIAV5FTW. This eliminates most all the supports required to print the core engine.

A simplified nacelle is available here:

This Nacelle is modeled after the Trent 900 Nacelle as used on the A380. It is designed specifically for the 3D Printable High-Bypass Jet Engine by CATIAV5FTW (Chris Shakal). I used his model with minimal changes and substitutions. While most of his original design remains intact, some parts must be replaced or modified. I have included remixed versions of most of his parts. The remixes simplify or eliminate the need for supports. A few of his parts are in their original format but are included with my numbering system added for convenience.

Note, While the nacelle was designed like the Trent 900, the core engine is not! The Trent 900 uses 3 counter-rotating spools. This engine has only 2 spools rotating in the same direction. Furthermore, the core engine is not designed after any particular real jet engine.

This model does not have operating reversers. It is more like the outer engines on the A380 that don't have reversers. Functional reversers are available separately.

A gearmotor is also available.

**** While the technical requirements to print and build this model are not great, there are a lot of pieces, and many are quite large. Some fitting, adjustment, and gluing may be required. Total cost of this project is around $175 (2025 USD). Print time may exceed 300 hours. It will be a rewarding project but will require significant time and dedication.

Note: Make sure you place the TN1-828 SWIRL_DOME_PLATE inside the TN1-703_COMBUSTION_LINING_BODY. I see many of these models with the dome plate incorrectly placed on the end of the combustion lining body. The fuel injectors will not line up correctly with the swirl dome in the wrong position. The swirl dome plate slides in from the side in a circular motion and may not even require adhesive if it's located correctly.

The STLs should already be in the correct orientation. The parts are large. At 300mm x 300mm x 400mm printer envelope is highly recommended. Optional split parts are provided so the model may be completed with a 206mm x 206mm x 185mm high build plate.

STL files with an S suffix on the part number have built in supports. No additional supports are required from the slicer if these files are used. They will save time and filament and should work better than slicer generated supports. NOTE: It is extremely important to use the recommended print settings (layer height, etc.) on STL files with built in supports. SOME BUILT IN PRINT SUPPORTS WILL BE IMPOSSIBLE TO REMOVE IF THE RECOMMENDED PRINT SETTINGS ARE NOT USED.
