Key Takeaways
- Eplus3D and UCL Rocket collaborate on a regenerative liquid oxygen (LOX) and isopropyl alcohol (IPA) liquid-cooled engine architecture
- The engine uses IPA as a coolant before igniting it with LOX in the combustion chamber, achieving high efficiency and potential for long burn times
- The cryogenic engine utilizes the temperature difference between LOX and combustion heat to insulate the rocket, preventing damage
- UCL Rocket's new architecture is more complex, with increased heat fluxes and temperature differences, compared to their previous engine
Introduction to the LOX IPA Engine
Eplus3D, a leading 3D printing company, has partnered with the University College London Rocket (UCL Rocket) team to develop a cutting-edge liquid rocket engine. The engine features a regenerative liquid oxygen (LOX) and isopropyl alcohol (IPA) liquid-cooled architecture, which has the potential to achieve high efficiency and long burn times.
Engine Architecture and Benefits
The engine's architecture is based on the principle of using IPA as a coolant before igniting it with LOX in the combustion chamber. This process allows for a high temperature difference between the LOX and the combustion heat, which is used to insulate the rocket and prevent damage. The use of LOX, which is cooled to -183°C to remain in a liquid state, enables the engine to carry a large amount of fuel, making it highly efficient. The following comparison table highlights the key features of the LOX IPA engine:
| Feature | LOX IPA Engine | Traditional Engines |
|---|---|---|
| Coolant | IPA | Water or other fluids |
| Fuel | LOX and IPA | Traditional fuels |
| Efficiency | High | Lower |
| Burn Time | Long | Shorter |
| Insulation | Temperature difference between LOX and combustion heat | Traditional insulation materials |
UCL Rocket's Previous Engine and the Race 2 Space Competition
UCL Rocket's previous engine, made from CuCrZr on the EP-M400S 3D printer, underwent a 5 kN hot-fire test for the Race 2 Space competition. This competition, sponsored by the UK's space agency and space companies, aims to increase the number of highly-skilled graduates in STEM subjects and the space industry. The new engine architecture, however, is more complex, with increased heat fluxes and temperature differences, posing a challenge for the team.
Conclusion and Future Prospects
The collaboration between Eplus3D and UCL Rocket has the potential to revolutionize the field of liquid rocket engines. The LOX IPA engine's high efficiency, long burn times, and potential for low costs make it an attractive option for the space industry. While the new architecture poses challenges, the team's innovative approach and use of 3D printing technology may lead to a breakthrough in engine design.
Bottom Line
The partnership between Eplus3D and UCL Rocket has resulted in a groundbreaking liquid rocket engine that could significantly impact the space industry. With its high efficiency, long burn times, and potential for low costs, the LOX IPA engine is an exciting development in the field of rocket propulsion. As the team continues to work on the engine's architecture and overcome the challenges posed by its complexity, the possibilities for this technology are vast and promising.
