Green Aero Conducts Test Firing of Sub-kN Liquid-Fuelled Aero Engine for High-Speed Drones
Green Aero Propulsion Private Limited has tested a sub-kN liquid-fuelled aero engine using airblast atomiser technology, designed for high-speed drones and Collaborative Combat Aircraft. The test confirmed the engine's subsystems and its capability to operate on multiple fuels. The engine features advanced cooling and manufacturing technologies aimed at enhancing performance and reducing part counts. Green Aero also developed a hydrogen-capable core named 'Blue Dragon' and has raised USD 1.6 million in funding for its projects.

Green Aero Propulsion Private Limited has successfully tested a sub-kN liquid-fuelled aero engine that utilizes airblast atomiser technology, aimed at powering high-speed drones and Collaborative Combat Aircraft. The recent test validated various subsystems, including turbomachinery and fuel injection.
The engine supports multiple fuels and features an electric start system and advanced cooling mechanisms. Manufactured with metal additive technology, it reduces part counts by nearly 70%. The propulsion unit targets the 20 kgf to 100 kgf thrust range.
Additionally, Green Aero has created a hydrogen-capable engine core called 'Blue Dragon'. The company raised USD 1.6 million in July 2025 and is establishing a propulsion test cell while recruiting engineers for further development.
