IISC-Bangalore Engineers Develop High-Performance Fuel Injector for Fighter Jet Engines

The Indian Institute of Science (IISc) Bangalore has achieved a significant milestone in advancing India's self-reliance in defense technology by developing a cutting-edge indigenous fuel injection system tailored for fighter jet engines. This innovation enhances the performance and efficiency of high-speed aircraft engines, marking a critical step in India’s defense and aerospace sector.

The fuel injection system designed by IISc focuses on producing finer atomized fuel droplets, ensuring more efficient combustion and reduced emissions. This system is particularly pivotal for afterburner-equipped engines, like those used in advanced fighter jets. Afterburners rely on the precise injection of additional fuel into the exhaust stream to dramatically boost thrust during combat or high-speed maneuvers. The IISc solution integrates advanced atomization techniques, improving both fuel delivery and the stability of combustion under varying operational conditions.

Supported by agencies such as the Aeronautical Research and Development Board (ARDB), the research incorporated high-speed diagnostics to optimize the interplay of fuel sprays, airflow, and combustion dynamics. This innovation will significantly contribute to the performance of engines for projects like India’s Advanced Medium Combat Aircraft (AMCA), a critical next-generation fighter jet under development.

This development not only aligns with the "Make in India" initiative but also strengthens India's strategic capabilities in aerospace technologies, reducing dependency on foreign systems. The system has the potential for further adaptation in various high-performance engines, ensuring broader applications in both military and civilian domains.
