A detailed CAD model of a miniature axial jet engine, designed from scratch as an independent aerospace engineering project. This repository contains the complete 3D assembly and component files.
This project involved the ground-up design of a miniature turbojet engine, covering all major subsystems from the intake to the exhaust. The goal was to apply aerodynamic and mechanical design principles to produce a realistic, manufacturable engine geometry.
For the non-engineer: a jet engine works by sucking in air, compressing it, mixing it with fuel and burning it, then blasting the hot gas out the back — the reaction force pushes the engine (and whatever it's attached to) forward. This model captures all those stages in a compact, miniature form.
| Component | Description |
|---|---|
| Intake | Converging inlet geometry for airflow capture |
| Compressor | 2-stage axial compressor with NACA airfoil blades |
| Combustion Chamber | Annular chamber design |
| Turbine | Single-stage turbine driving the compressor shaft |
| Exhaust Nozzle | Converging nozzle for accelerated exhaust |
| Full Assembly | Complete engine assembly with all components mated |
