Ôh Toulouse...
CBOne is pleased to be present at the 26th Conference of the International Society for Air Breathing, in Claude Nougaro's city from 22 to 27 September 2024.
Mrs Andrea Hofer from CBOne will present the successful demonstration of Sequential Recursive Combustion, a safe and robust lean-burn concept for aviation.

Paper 157: Experimental Validation of a Recursive Sequential Combustor and Study of the Model
Sequential recursive combustion is a proprietary CBOne technology that we have been working on since the early 2020s. Recently, thanks to an approach that makes good use of additive manufacturing methods, we have been able for the first time to achieve sequential recursive combustion using multiple burners arranged in a loop. The results in terms of good emission performance and lean flame robustness are there for all to see.

Hiring young talents: A hydrogen named desire

Towards desirable H2 machines
... that are simply better than the state of the art with conventional fuels. This is within reach.
CBOne is offering for internships to work on technical subjects relating to hydrogen, with recruitment opportunities by 2025. Are you a mechanical or process engineering student? Are you interested in fluid mechanics, energy and gas turbines? We'd like to hear from you.
The subject covers the following topics:
- Design of a burner capable of operating at 100% with hydrogen in premixed mode, towards stoichiometry close to one
- The safety of using hydrogen, particularly with regard to the risk of detonation
- Thermal management and transitions of hydrogen as a working fluid, from the cryogenic state to the gaseous state in the positive temperature range. Use of hydrogen's high calorific value as a coolant.
- Design of thermal machines capable of operating with moderately hot gases (around 1000°C), using hydrogen highly diluted in air, where the lack of thermal efficiency is offset by the simplicity of cooling, if any.
- Improving the combustion performance of conventional fuels by adding hydrogen: thermal performance, emissions performance (NOx, CO, soot, unburnt fuel), stability performance (passivation of combustion instabilities), combustion range performance (towards ultra-lean regimes).

KI-Pirinha: intelligent protection versus H2-detonation

- Published on Monday, 01 April 2024 08:34
KI-PIRINHA stands for Key enabling technologIes on Performance, Efficiency and Resilience by Artificial INtelligence for Hydrogen Applications.
Contrary to its name, the aim of this research project is the avoidance of a detonation cocktail at all costs.
It aims to develop viable technical solutions to improve the safety and operational efficiency of H2-powered applications by combining the knowledge of experts in combustion research (CBOne) and experts in the simulation and control of complex dynamic systems using AI (FH JOANNEUM, Institute of Aviation). FH JOANNEUM is the project leader. This Austrian national research project is funded by BMK and FFG.

No, no, don't kick our Franco-Austrian team out of the Proud Albion! What we mean by this slightly provocative title is that we'll be presenting hot topics in the field of combustion at this year's Turbomachinery Conference, which is being held at London's Excel Conference Centre, overlooking the River Thames.
Project LIQORNE – a dependable LH2 fuel system

The world moves towards renewable, low emission fuels and this development includes aviation. Hydrogen enables clean, CO2-free combustion, but the stored liquid fuel needs to be cold – very cold. Temperatures lower than -252°C to be exact.
