Kaveri dry engine clears Russia trials, exceeds thrust target

India's indigenous Kaveri dry engine has completed a round of high-altitude and flight trials in Russia, recording a peak dry thrust of 48.5 kilonewtons (kN). The figure is higher than the roughly 46 kN the powerplant was originally required to produce.

The trials covered both high-altitude conditions and flight testing, marking a further step in the long-running development of the Kaveri programme. The engine is a dry variant, meaning it operates without an afterburner.

With the test campaign concluded, the engine is positioned to power a new class of Indian stealth drones. The thrust margin over the design requirement is significant for an unmanned platform, where available power shapes payload, altitude and endurance.

The Kaveri has been developed domestically as part of India's push for self-reliance in propulsion technology, a field where the country has historically depended on foreign suppliers. The latest results give the programme a measured performance gain over its stated specification.
