Defence major Hindustan Aeronautics Limited (HAL) and Safran Aircraft Engines signed a long-term agreement for the production and supply of turbine ring forgings in superalloys for the CFM LEAP engine programme. The deal was signed on the sidelines of the Farnborough International Airshow in the UK.

Superalloy ring forgings are used in elevated-temperature applications of the rotating section of the aero-engine and are critical to engine performance and reliability. Forging is a fundamental manufacturing process involving the shaping of metal using compressive forces.

Under the agreement, HAL will manufacture near-net shape ring forgings for the LEAP engine at its state-of-the-art Ring Rolling facility in Bengaluru.

LEAP engine is an advanced, high-bypass turbofan engine produced by CFM International, which is a joint venture between GE Aerospace and the Safran Aircraft Engines.
