Hydrogen-powered jet engine has the potential to reduce climate impact of civil aviation. Compared to kerosene-powered jet engine, some components might need to be designed to handle slightly elevated temperatures due to the higher combustion temperature. With densities around three times lower than conventional nickel based alloys and higher operating temperatures  
Ceramic Matrix Composites (CMCs) are promising candidates for hydrogen-powered jet engine.
In this presentation a status quo of the literature and project researches for CMCs components in hydrogen-driven jet engine will be done.
The potential of SiC/SiC CMC nozzle guide vanes will be presented [1]. The suitability of the cost efficient non-oxide C/C-SiC CMC for piston rings will be shown [2,3].
Challenges and opportunities for CMC applications in future aircraft engine will be highlighted through this presentation.
