Innovative Thrust Chambers for Hydrogen Based Low Emissivity Propellants

ongoing

The technology being advanced in this proposal is the design and development of an innovative ceramic-based combustion chamber for aerospace engines (both aeronautics and space) powered by hydrogen. The primary goal is to leverage the high power and low visibility of H2/O2 and H2/air flames. These unique characteristics, which offer significant advantages for defense systems (such as higher cruise velocity and reduced detectability), are however accompanied by extremely high combustion temperatures that exceed the capabilities of current combustion chambers, whose materials melt well below the H2 flame temperature. To address this, an innovative combustion chamber made from ultrahigh temperature ceramic matrix composites, inherently capable of wall thermal protection, will be developed. A secondary goal of this project is to foster European expertise in advanced defense technologies related to high-temperature composite ceramic materials. This capability is essential for ensuring selfreliance and advancing EU-based innovations in defense and aerospace applications. The project includes initiatives like developing material processing technologies, setting up dedicated research infrastructures, and establishing training programs to cultivate skilled talent. The integration of these efforts could further reinforce the EU’s position as a leader in high-temperature composite ceramics and support broader objectives of strategic autonomy in aerospace defense technologies.
