J-2C is a realistic, mechanically accurate two-stage centrifugal turbojet at real-world scale, with its complete internal assembly. Every part is a separate, named object.

FULLY ANIMATED - RUNS LIKE A REAL ENGINE

- Starts from rest, spools up and runs at a steady 5,000 rpm (600 frames, 60 fps)

- 77 moving parts turn at their true gear ratios: impellers, shaft, turbine wheels, bearing races, cages and rolling elements, tower shaft, gearbox and oil-pump gears

- Animation baked into the FBX, GLB and Blender files at 8 samples per frame, so the high-speed spin plays correctly in game engines

- Blender scene adds a one-control rig, fuel spray, igniter sparks, combustion flame, cooling exhaust plume (volumetric), engine sound and a running cutaway copy
