LOX engine learning lab
3D simulation of a simple LOX engine.
Explore a cutaway liquid-oxygen engine model, internal combustion animation, cooling jacket flow, injector mixing, and engine readouts for engineering education.
Internal Combustion
LOX and fuel enter through injector elements, atomize, mix, ignite, and expand through the nozzle. The animation shows flow direction and qualitative flame behavior.
Cooling Jacket
The chamber wall is protected by regenerative cooling. Higher coolant flow improves thermal margin but adds pressure-drop and pump work tradeoffs.
Control Learning
Throttle, mixture, pressure, injector swirl, and cooling sliders update estimated temperature, mass flow, thrust, Isp, and stability so teams can explore design intuition.
1. Injector
Creates fine oxidizer and fuel streams so combustion happens smoothly rather than in damaging pressure waves.
2. Chamber
Confines hot gases long enough to release chemical energy and build pressure before expansion.
3. Throat
Chokes the flow, setting mass flow for a given pressure and gas state.
4. Nozzle
Expands hot gas and converts thermal energy into directed exhaust velocity.
5. Sensors
Engineers watch chamber pressure, temperature margins, vibration, valve timing, and injector stability during tests.
6. Review
Use this as a classroom and review-board tool, not as certified real-engine control or fabrication guidance.
