What it takes to rule the H

Papers GT2022-80886 and GT2022-82420 at ASME Turbo Expo 2022 (Conference Talk)

Mrs Hofer and Mrs Paulitsch from CBOne will present their research published in two papers in Rotterdam at the ASME Turbo Expo 2022 Conference, June 13 - 17, 2022. While Hydrogen combustion is clearly at the heart of one technology called Bluetifuel, the second technology called MOeBIUS is an up-and-coming option for the design of lightweight, compact, and very high energy density combustion chambers in future hydrogen-powered aeronautical propulsion systems.

 H2llo you :)


Our latest updates on Pure Hydrogen Combustion (Bluetifuel project, FFG / ClimaFonds Energy Call 2019 / Contract Nr. 881129 in partnership with P&P Industries AG and FH JOANNEUM GmbH / Aviation) and on Recursive Sequential Combustion (MOeBIUS project, FFG / Take-Off call 2019 / Contract 881041) will be presented:

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.

Successful Maiden Fire for the First Full AM-Burner Designed by CBOne!

Ok - the title for this article was temporarily changed to "* * Ô la Belle Bleue  !!! " because of some footballistic interference during the summer 2018. Shortly said: Bravo les Bleus, Merci pour cette deuxième étoile! That was it, back to combustion now! 

The first full 3D printed burner designed by CBOne was tested with success. 

This validates our capacity to design a complete burner fit for operation under gas turbine conditions (natural gas-fired, premixed lean combustion, two-stage with a low swirl pilot embedded in a high swirl main), with additional features versus conventional such as a monolithic form, low finishing requirements, advanced thermal management, integrated ignition and prepared instrumentation ports for an advanced monitoring.

Additive Manufacturing: The New Forge (Turbo Expo 2018)

The freedom of design using Additive Manufacturing (AM) opens the door towards new shapes and new designs. In combustion engineering, this is the opportunity to make better burners.

CBOne was present at the ASME Turbo Expo in Oslo, Norway, from the 11th to the 15th of June 2018. In collaboration with our colleagues from Joanneum Research GmbH and FH JOanneum in Graz, Austria, we made a study about shape factors for a novel type of swirler.
