Kaveri Engine Clears Russian Trials, Paving Way for Indigenous Stealth Unmanned Combat Aerial Vehicle (UCAV)
By Drooid · · How we work
Russian High-Altitude and Flight Tests
India’s Defence Research and Development Organisation (Defence Research and Development Organisation's (DRDO)) Gas Turbine Research Establishment (GTRE) successfully completed high-altitude ground and flight trials of the Kaveri Derivative Engine (KDE) at Russia’s Central Institute of Aviation Motors (CIAM) and Gromov Flight Research Institute. The engine, a non-afterburning version of the original Kaveri, achieved a peak dry thrust of 48.5 kilonewtons (kN), exceeding the target of roughly 46 kN. Test flights used a modified Ilyushin Il-76 testbed in which a standard engine was replaced by the KDE, allowing evaluation across varied ambient pressures, Mach numbers and thrust demands.
Certification and Integration Process
Following the trials, the Centre for Military Airworthiness and Certification (CEMILAC) in Bengaluru will review the test data before granting air-worthiness clearance, according to a defence source. The source added that, after certification, the engine will be integrated with the Ghatak unmanned combat aerial vehicle (UCAV) and subsequently undergo flight trials in cooperation with the Indian Air Force. The same source indicated that induction of the engine-powered UCAV is expected within 2–3 years.
Ghatak Stealth UCAV Overview
Ghatak is a tailless, flying-wing combat drone designed for deep-strike missions. Its airframe incorporates 80–90 % carbon-fibre prepreg composites, reducing weight and radar cross-section. The UCAV will carry missiles, bombs and precision-guided munitions internally to preserve a low-observable profile and is intended to operate alongside manned fighters such as Tejas and the future AMCA.
Significance for India’s Aviation Ambitions
The successful Russian trials mark a milestone in India’s decades-long effort to develop indigenous jet engines, a capability first pursued in the late 1980s for the Light Combat Aircraft (LCA) Tejas. If certification and integration proceed as planned, the KDE could become a domestic powerplant not only for Ghatak but also for other future unmanned platforms, reducing reliance on foreign engines.
Upcoming Milestones
- CEMILAC review of trial data (pending).
- Engine certification before integration with Ghatak.
- Flight trials of the KDE-powered UCAV in collaboration with the Indian Air Force, projected within the next two to three years.
