The Defense Metallurgical Research Laboratory (DMRL) under the Indian Defense Research and Development Organization (DRDO) has developed a near-isothermal forging technology for the production of titanium alloy components for aircraft engines. At present, the Indian Defense Research and Development Organization is using this forging technology to manufacture aero-engine high-pressure compressor discs made of titanium alloy on its 2,000-ton isothermal forging press.
It is reported that DMRL has signed a technology transfer license agreement (LAToT) with India's MIDHANI, and plans to use DMRL isothermal forging equipment and MIDHANI to jointly produce 200 high-pressure compressor discs, and provide parts for Hindustan Airlines (HAL) to produce Adour engines. DMRL revealed that the compressor discs produced with this technology have passed the type certification and can meet all the requirements set by the airworthiness department. Both HAL and the Indian Air Force have approved the use of such compressor discs. In addition to DMRL and HAL companies, MIDHANI, Indian Military Aircraft Airworthiness and Appraisal Center (CEMILAC), and Indian Aviation Quality Assurance Agency (DGAQA) and other institutions have recognized this technology.
