Viraj Aero Proposes Steam Injection for Enhanced Gas Turbine Efficiency in Aviation

Viraj Aero is introducing steam injection technology into aviation gas turbines through its Eyja engine, targeting a 30% reduction in fuel consumption compared to existing turboprop engines. This technology, adapted from industrial power plants, leverages water vapor from combustion gases, creating a closed-loop system that eliminates the need for heavy water tanks on aircraft.

The startup's presence in Toulouse-Blagnac enhances collaboration with major aerospace stakeholders, accelerating development timelines. Notably, steam injection also addresses non-CO₂ emissions, which constitute approximately two-thirds of aviation's climate impact, thus providing a comprehensive solution for decarbonization. The integration of hydrogen fuels further amplifies efficiency gains, establishing a synergistic relationship between the two technologies.
