A Future Named Hydrogen
It took us time to write this title. We needed time indeed to get convinced. We went through the process. We manipulated hydrogen combustion. Now we are sure: hydrogen is the future of combustion. A bright future.
Why did it take us so long?
High-fidelity optical fast-pressure sensing (conference article)
A better combustion monitoring is made possible using the advanced optical pressure sensor and advanced processing techniques developped by Meggitt SA, with the help of Combustion Bay One e.U. These works are presented at the European Conference of the Prognostics and Health Management Society 2021.

Combined Optic-Acoustic Monitoring of Combustion in a Gas Turbine (Journal Publication)
A compact, high temperature- and pressure-resistant probe was developed with success in the frame of the FFG / Take Off / emo(o)tion projects. This probe combines acoustic and optical sensors for a better description of the gas turbine combustion, in-situ.
The results of the probe are published in the International Journal of Turbomachinery for Propulsion and Power. The article is open access. The reference is:

MOeBIUS: Recursive Sequential Combustion (Conference Talk)
Paper GT2021-59592 at ASME Turbo Expo 2021
MOeBIUS stands for a Momentum-Enhanced Blend of the Reactants With Recirculated Burnt Gases. It is a novel concept for high-efficiency and low-emission combustion, developed by CBOne with the support of the FFG.
The concept and the combustor design are presented at the ASME Turbo Expo 2021, Virtual Conference and Exhibition: June 7 – 11, 2021. Its principle is called recursive sequential combustor, a synonym for arranging the burners behind each other and in a circle, so that a considerable part of burnt gases emitted by one burner enters the next.

Forcing Pulsations by Means of a Siren for Gas Turbine Applications (Journal Publication 2020)
An article summarizing 20 years of experience about CBOne's pulsation Technology and focusing on the very latest developments has been published in the International Journal of Turbomachinery for Propulsion and Power. To this point, we wish to thank the Board of the EVI-GTI Conference for their recommendation for journal publication.
CBOne developed a special actuator, able to generate with precision airflow modulations over the 0-6000 Hz range, with amplitudes achieving up to 150 dB SPL. The article describes into details:
- The siren technology
- The generation of a precision airflow modulation, for dynamic sensor calibration purpose
- The drive of flow dynamics, for laboratory applications
- The drive of thermoacoustics, for gas turbine applications
