A team of engineers at the Indian Institute of Science (IISc) has achieved a major breakthrough in aerospace technology by developing a cutting-edge fuel injector system designed for advanced fighter aircraft. This innovative technology is slated to be integrated into India's fifth-generation Advanced Medium Combat Aircraft (AMCA).
"We've developed a new high-performance, high-shear swirl injector," explained Professor Saptarshi Basu, the lead investigator of the project, in an interview with the Times of India. "It produces exceptionally small droplets, which are crucial for efficient fuel-air mixing and complete combustion."
This indigenous technology, developed under a Defence Research and Development Organisation (DRDO) program, signifies a major step towards self-reliance in critical defence technologies. The IISc team collaborated with DRDO's Gas Turbine Research Establishment (GTRE) to create an injector that surpasses existing commercial alternatives in several key performance parameters.
"The high-shear fuel injector, produced using advanced 3D printing techniques, outperforms existing solutions in droplet sizing, spray pattern formation, flame stability, and flow field consistency," Basu stated.
The injector underwent rigorous testing at IISc's world-class experimental facilities, validating its superior capabilities. Basu highlighted the project's blend of fundamental research and practical application, stating, "This achievement represents a perfect marriage between fundamental fluid mechanics research and practical applications in aerospace technology."
While a definitive timeline for testing on the AMCA, which is still under development, remains to be finalized, Basu indicated that the injector could also be adapted for use in civil aircraft with minor modifications.
This project has not only resulted in scientific publications and patents but has also provided valuable training for students in advanced aerospace technology. The successful development has garnered praise from the DRDO, solidifying its significance in India's pursuit of self-sufficiency in defence technology.
This development comes at a crucial time for the AMCA program. India is aiming to develop a fifth-generation fighter jet with advanced capabilities, including stealth technology and supercruise. A high-performance fuel injector is essential for achieving these goals, as it directly impacts the engine's efficiency and thrust.
While the AMCA is still in development, this breakthrough signifies a crucial step towards its realization.
