In a recent technological breakthrough, Defence Metallurgical Research Laboratory, a premier metallurgical laboratory of DRDO at Hyderabad, has developed a way to produce critical aero-engine components.
And with this, India has joined the league of limited global engine developers to have the manufacturing capabilities of such critical aero-engine components.
The technology is hard to achieve as a country like China is also struggling to develop cutting-edge technology that can fuel aircraft engines.
DRDO has created a near isothermal forging technology to produce aero-engine components using its unique 2000 MT isothermal forge press. This is built with difficult-to-deform titanium and nickel-based alloys,….which can withstand temperatures of more than 1,000 degrees Celsius.
This development enables India to power its jet engines indigenously.
With the production of aero-engines components with such high-pressure compressors discs through the isothermal forging technology…. India is now among limited nations across the globe with manufacturing capabilities of such critical aero-engine components.
Based on the exhaustive component level and performance evaluation test results, HAL (E) and Indian Air Force cleared the components for engine fitment. Apart from DMRL and HAL (E), various agencies such as MIDHANI, CEMILAC and DGAQA worked in unison to establish this crucial technology.
As of now, along with MIDHANI, Defence Metallurgical Research Laboratory (DMRL) has produced 200 HPC discs.
The discs have been supplied to HAL’s Engine Division in Bengaluru for installation in the Adour 804/811 and 871 engines that run the Indian Air Force’s Jaguar/Hawk Aircrafts.
What is isothermal forging technology?
In metallurgy, the process of Forging is termed as shaping metal and increasing its strength by hammering or pressing.
In Isothermal forging, the die and the workpiece are maintained at the same temperature throughout the forging cycle.
This technology is widely used to forge titanium-based alloys which makes it best suited for the high-pressure compressors discs that are used in aero-engines.
The fighter jet engine needs components with the highest precision, as a small deformity can lead to huge damage and this technology provides the components with the highest precision.
The components produced through the technology are very close to the final (net) shape, reducing the need for surface finishing. More than two-thirds of the production cost is reduced by eliminating traditional finishing processes like machining or grinding.
DRDO’s technological breakthrough has put India on the world platform to create high-end technology in the defence sector. This will further open doors for the nation to build a completely indigenous aircraft.
That is all in this segment, keep watching for more updates on India’s remarkable breakthroughs!
