The Defence Research and Development Organisation (DRDO) has established the near isothermal forging technology to produce all the five stages of high-pressure compressors (HPC) discs out of difficult-to-deform titanium alloy using its unique 2000 MT isothermal forge press.
The Defence Metallurgical Research Laboratory (DMRL), a premier metallurgical laboratory of DRDO at Hyderabad, developed this technology.
“This is a crucial technology for establishing self-reliance in aero-engine technology. With this development, India has joined the league of limited global engine developers to have the manufacturing capabilities of such critical aero engine components,” the Ministry of Defence said in a statement.
DMRL has transferred the technology to M/s MIDHANI through a licensing agreement for technology transfer (LAToT) to meet the bulk production requirements.
DMRL developed this forging technology by integrating various science and knowledge-based tools. The methodology adopted by DMRL is generic in nature and can be tuned to develop other similar aero-engine components.
The compressor discs produced using this methodology met all the requirements stipulated by the airworthiness agencies for the desired application.
Accordingly, the technology was type certified, and a letter of technical approval (LoTA) was accorded. Based on the exhaustive component level and performance evaluation test results, HAL and Indian Air Force cleared the components for engine fitment.
Introducing ElectionsHQ + 50 Ground Reports Project
The 2024 elections might seem easy to guess, but there are some important questions that shouldn't be missed.
Do freebies still sway voters? Do people prioritise infrastructure when voting? How will Punjab vote?
The answers to these questions provide great insights into where we, as a country, are headed in the years to come.
Swarajya is starting a project with an aim to do 50 solid ground stories and a smart commentary service on WhatsApp, a one-of-a-kind. We'd love your support during this election season.
