An interactive 3D model of the General Electric F110-GE-129 afterburning turbofan, the engine in the F-16C Block 50/70. It runs in a web browser. The engine is driven by a calibrated Brayton-cycle model: move the throttle from cutoff through idle and MIL to max afterburner, and the spools, gas flow, flame, nozzle and cockpit gauges respond.

- Engine geometry. 3-stage fan, 9-stage HP compressor, annular combustor with 20 fuel nozzles, 1-stage HP turbine, 2-stage LP turbine, mixer, augmentor and a variable convergent-divergent nozzle. The LP and HP spools counter-rotate.
- Throttle. Cutoff, idle, part power, MIL and afterburner zones 1–5. From cutoff, the start sequence motors the engine on the JFS, lights off at 20% N2 and accelerates to idle.
- Gas flow. About 9,000 particles. Color them by total temperature, total pressure, velocity, or core/bypass stream. The combustor flame, afterburner flame, exhaust plume and shock diamonds scale with power.
- Exploded view. Modules separate along the engine axis, and the casings can lift off.
- Section views. Quarter cutaway, half (top or front), or a cross-section slice you can move along the engine.
- Systems isolation.
- Rotating spools
- Fuel, main and afterburner
- Lube oil
- Bleed and anti-ice
- Accessory drive
- Engine control (FADEC)
- Variable geometry and nozzle actuation
- Cockpit instruments. F-16-style RPM, FTIT, nozzle-position and oil gauges, plus a fuel-flow counter, a thrust-vs-throttle curve and a live gas-path station table (stations 0–9).
- Part cards. Click any part for its function, typical material, specs and live values.
- Engine sound. Synthesized with Web Audio; turn it on from the panel.
Model results at sea-level static, standard day:
| Setting | Thrust | Fuel flow | FTIT | Nozzle |
|---|---|---|---|---|
| Idle (70% N2) | ~944 lbf | 1,626 pph | 419 °C | 100% |
| MIL | 17,155 lbf | 13,590 pph | 945 °C | 9% |
| Max AB | 29,500 lbf | 52,340 pph | 945 °C | 59% |
- MIL and max-AB thrust are calibrated to match published figures. Airflow (270 lb/s), overall pressure ratio (30.7) and bypass ratio (0.76) are also published values.
- FTIT, nozzle position and fuel flow are computed by the model. They fall inside the GE-129 operating limits listed in the spec sheet.
- Values between those points, blade counts and the five afterburner zones are representative. They are not GE data.
