Viraj Aero
Viraj Aero develops steam-injected turbine technology that operates in a closed loop, recovering exhaust heat and water to improve efficiency without an external water supply. The system targets up to 40% lower fuel consumption and CO2 emissions, up to 30% greater power output, and up to 99% reduction in NOx emissions. The technology is applied in the EYJA engine for light aviation and the GENA system for on-site power generation at data centers and AI facilities.

Problem
Conventional gas turbines operate with significant thermal inefficiency, wasting exhaust heat and producing high levels of NOx emissions. Steam injection can improve turbine performance, but traditional approaches require an external water supply and heavy condensation equipment, making them impractical for aviation and many distributed power applications.
Solution
Viraj Aero develops steam-injected turbine technology that operates in a closed loop without needing an external water supply. The system recovers exhaust heat through a heat exchanger to generate steam, which is injected into the combustor to increase mass flow through the turbine and moderate peak combustion temperatures. A proprietary lightweight condenser then captures water vapor from the exhaust and returns it to the steam-generation loop. This approach delivers up to 40% lower fuel consumption and CO2 emissions, up to 30% greater power output, and up to 99% reduction in NOx emissions. The technology is applied across two product lines: the EYJA engine for light aviation and the GENA system for on-site power generation at data centers and AI facilities.
Target Audience
Primary customers include aircraft manufacturers and operators seeking more efficient propulsion for light aviation, as well as data center operators and AI infrastructure providers needing compact on-site power generation with lower emissions.
