The Kaveri turbofan engine is set to begin flight testing on a TEJAS prototype with a “hollow reheat” afterburner module, which will validate airflow, temperature, and integration parameters before advancing to full afterburner capability. This phased approach reduces technical risk by maturing thermal margins and nozzle control, crucial for future fighter and unmanned combat aerial vehicle (UCAV) use. The dry variant of the Kaveri, developed with French firm Safran, is optimized for stealth and efficiency and is currently in the final testing phase in Russia, targeted for certification by 2026. This engine variant is intended for the Ghatak stealth UCAV program, reinforcing India’s strategy to develop indigenous propulsion systems and reduce reliance on foreign engines for modern combat aircraft. The program, initiated in the 1980s, reflects ongoing efforts to achieve Aatmanirbhar Bharat in aerospace propulsion. Flight testing on the TEJAS prototype with the hollow reheat module is expected to provide critical data for future development phases. This initiative marks a significant milestone in indigenous aerospace technology and aligns with strategic defense goals.
