R-2130 RegioJet — 3D CAD Concept Revival Project

Main R-2130 site

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.

Pack B — RC Maker Pack (DXF + 3MF)

Includes:

• Full DXF cross-section slices (wing + fuselage) for laser cutting
• Up to ~50 fuselage stations
• Wing rib sections
• Clean orthographic section cuts
• 3MF file for RC layout reference
• Both engine options included

Perfect for: RC aircraft builders · Laser-cut foam/balsa makers · Workshops
