The Kaveri 2.0 engine programme, a proposed next-generation engine for the Tejas fighter aircraft, has been facing significant delays due to the lengthy approval process in India. Former Defence Research and Development Organisation (DRDO) scientist Ravi Kumar Gupta has expressed his concerns over the decision to delink the Kaveri programme from the Tejas, citing funding cuts and near-shutdown.
Gupta believes that the separation of the engine programme from the Tejas caused the funds to get cut, and the Kaveri project was on the verge of being shut down. However, the programme was revived only after the development of the dry Kaveri engine, which demonstrated around 48.5 kN of thrust.
Gupta argues that India now has substantially more indigenous expertise and technology than when the original Kaveri programme began, providing a better foundation to launch a new development effort. He suggests that a new Kaveri 2.0 programme could aim at 80-90 kN of thrust, which could be potentially developed for applications other than the original Kaveri requirement.

However, this would require significantly more than merely bumping up the Kaveri's thrust to meet the fighter's requirements for reliability, dimensions, weight, fuel consumption, durability, and integration with the airframe.
Gupta also argues that the technology developed through a Kaveri 2.0-class core could eventually have applications in the civilian aviation sector. He suggests that a high-bypass-ratio derivative could be developed from the technology base for commercial aircraft applications. Such an engine could potentially support future Indian transport-aircraft programmes, including a Medium Transport Aircraft (MTA) concept using a twin-engine configuration.
However, a civil derivative would require a different architecture and extensive additional development and certification. A fighter engine and commercial turbofan have very different requirements for fuel efficiency, noise, reliability, operating life, and certification.
Gupta also criticises what he describes as inadequate domestic ground infrastructure for advanced aero-engine development. High-thrust turbofan development requires specialised test facilities, including engine test beds capable of validating the complete engine across operating conditions. Without sufficient indigenous testing infrastructure, developers can face delays even after the core technology has been developed.
In conclusion, reviving the Kaveri 2.0 engine programme is a strategic imperative for India, as it could provide a significant boost to the country's indigenous defence capabilities and potentially open up new opportunities in the civilian aviation sector. By addressing the challenges and concerns raised by Gupta, India can take a crucial step towards realising its vision of becoming a self-reliant defence power.
