On 22 July 2026 Hindustan Aeronautics Limited (HAL) and Safran Aircraft Engines signed a long‑term agreement for production and supply of turbine ring forgings in superalloys for the CFM LEAP engine programme; manufacture will take place at HAL’s Ring Rolling facility, Foundry & Forge Division, Bengaluru.
Agreement — scope
- Components: turbine ring forgings in superalloys for high‑temperature sections of LEAP turbofans.
- Manufacturing site: HAL Ring Rolling facility, Foundry & Forge Division, Bengaluru.
- Programme: CFM LEAP family (LEAP‑1A, LEAP‑1B, LEAP‑1C) used on Airbus A320neo, Boeing 737 MAX and COMAC C919.
Technical and production facts
- Superalloys: predominantly nickel‑based alloys engineered for creep and oxidation resistance at >600°C.
- Ring rolling: hot forging process producing annular rings with directional grain flow for improved fatigue life.
- Acceptance requirements: aerospace forgings require defined chemistry, heat treatment, non‑destructive testing and full traceability.
Industrial and institutional facts
- HAL: Central public sector undertaking with foundry and forging capabilities for civil and military aero programmes.
- CFM International: joint venture of Safran Aircraft Engines and GE Aerospace; maker of CFM56 and LEAP engine families.
- Supply‑chain impact: contract places India as a production location for critical LEAP components under manufacturer approvals.
IASPOINT Booster Facts
- LEAP technology: uses composite fan blades and ceramic matrix composites in hot sections to improve efficiency.
- Controls: aero‑engine parts are subject to export and industrial quality controls and OEM approvals.
