Paninian India Private Ltd unveiled the Yantur 4.5 kN turbofan engine programme on 20 July 2026 for indigenous propulsion of long‑range autonomous systems, including combat drones and cruise missiles.
Key technical features
- Thrust rating: Core designed at 4.5 kN; architecture scalable to about 12.5 kN for larger platforms (Svayatt CCAV/Svayatt L1).
- Engine class: Compact turbofan suitable for unmanned aerial systems and cruise‑missile applications where size, fuel efficiency and endurance matter.
- Development status: Conceptual and detailed design complete; subsystem testing, validation and engine‑level certification underway.
- Proprietary technologies: Five patent claims covering engine family architecture, combustor and diffuser‑nozzle design, compressor technology, digital‑twin health monitoring and advanced manufacturing methods.
- Industry base: Development activity centred in Bengaluru and Hyderabad.
Strategic and procurement linkages
- Sovereign propulsion: Programme aims for domestic control of critical engine design and production for defence platforms.
- Make‑I association: Linked to the Ministry of Defence’s Make‑I category for private‑sector development of indigenous defence equipment, including long‑range land‑attack cruise missiles.
IASPOINT Booster Facts
- Turbofan: A gas‑turbine engine producing thrust via a fan and a core flow; common in subsonic propulsion and compact UAS engines.
- kN: Kilonewton, unit of force (1 kN ≈ 100 kgf under standard gravity ≈ 224.8 lbf).
- Digital twin: Virtual replica of a physical system used for real‑time monitoring, predictive maintenance and test‑validation.
- Patent focus areas: Compressor, combustor, nozzle aerothermodynamics and manufacturing techniques are central to turbofan performance and survivability.
