What is it about?
Gas turbine engines used for power generation and aerospace propulsion have traditionally used fossil fuels. To achieve zero emissions there is a need for cleaner fuels such as hydrogen. The aim of this paper is to use a combustor to study the use of ceramic matrix composites (CMCs) as an alternative material. The combustor developed for this project subjects the CMC material to elevated pressures and similar conditions to what it would experience in a real gas turbine engine.

Why is it important?
Our aim is to develop a CMC material that would be able to withstand the operating conditions of hydrogen combustion so we can transition from the use of fossil fuels to a more cleaner aviation and power generation industry.
Perspectives
This article gives a general explanation of why we need to switch from fossil fuels to Hydrogen and the main challenges to perform that transition. Also explains the general elements of experimental rigs used for the study of hydrogen combustion and shows the preliminary results obtained in the study.
