DRDO ESTABLISHES NEAR-ISOTHERMAL FORGING TECHNOLOGY TO PRODUCE ALL FIVE STAGES OF HPC

Highlights
• The Ministry of Defense said that “With this development, India has joined the league of limited global engine developers to have the manufacturing capabilities of such critical aero-engine components.”

According to an announcement made by India’s Defence Research and Development Organisation (DRDO), it has been successful in developing a jet engine with the thrust to power a fighter in combat.
The Ministry of Defence (MoD) on Friday made an announcement where it said that “The DRDO established the near-isothermal forging technology to produce all the five stages of high-pressure compressor (HPC) discs out of difficult-to-deform, titanium alloy, using its unique 2000 MT (metric tonne) isothermal forge press.”
The ministry further said that “With this development, India has joined the league of limited global engine developers to have the manufacturing capabilities of such critical aero-engine components.”
This technology to produce the five-stage HPC discs, was developed by , the Hyderabad-based Defence Metallurgical Research Laboratory (DMRL) and by using the isothermal forge press facility available at DMRL, Hyderabad, DMRL & MIDHANI have jointly manufactured 200 HPC disc forgings pertaining to various compressor stages. All these HPC discs have been supplied to HAL’s Engine Division in Bengaluru for fitting into the Adour 804/811 and 871 engines that power the Indian Air Force’s (IAF’s) Jaguar/Hawk Aircrafts.
