R-2130 RegioJet — 3D CAD Concept Revival Project
A modern re-imagining of Indonesia’s cancelled N-2130, rebuilt as a complete 21st-century digital aircraft.
The R-2130 RegioJet is a modernized digital revival of Indonesia’s unrealized N-2130 jetliner program. This is not an official PTDI product — it is an independent engineering concept, rebuilt in full 3D using modern CAD lofting and surface modeling techniques.
This aircraft is imagined as:
- A next-generation successor to the original N-2130
- A 100–130 seat, A220/E2-class regional jet
- A clean-sheet aerodynamic redesign
- A tribute to Indonesia’s aerospace ambitions
- The entire model is engineered in SolidWorks using true NURBS lofted surfaces, giving it wind-tunnel-grade smoothness and precise aerodynamic form.
- Every external surface — wings, fuselage, nacelles, empennage — is crafted using parametric engineering lofts suitable for 3D printing, rendering, CFD study, and RC design.
What You Can Do With These Packs
Depending on the pack you choose, you can:
- 3D print the aircraft
- Build RC laser-cut models
- Perform CAD or CFD analysis
- Render it in Blender
- Create posters, stickers, and merch
- Study the engineering form
