The Defense Metallurgical Research Laboratory (DMRL), a laboratory of the Defense Research and Development Organization (DRDO), manufactures key components such as the Adour engine (which powers the Jaguar attack aircraft) and the Kaveri engine’s discs, shafts and flicks Has developed an indigenous isothermal Forging technology to do so.
With this, India joins the League of Limited Global Engine Developers, which has the potential to manufacture such important aero engine components.
*Aerospace is an important technology for establishing self-reliance in aeroengine technology. The technology is generic in nature and can be used to build other similar aero engine components.
*High-pressure compressors (HPC) using DMRL’s 2000 megaton (MT) isothermal forge press can be used to create all 5 levels of hard disk-deformed titanium alloy.
*For the advancement of technology, DMRL has partnered with companies such as MIDHANI, the CEMILAC Military Airworthiness and Certification Center and the Directorate General of Aeronautical Quality Assurance.
LAToT to MIDHANI for Bulk Production
*To meet the total production requirements, DMRL transferred the technology to MIDHANI (Mishra Dhatu Nigam Limited), a public sector company, through a Technology Transfer License Agreement (LAToT).
*Using the facilities at the DMRL Laboratory in Hyderabad, DMRL & MIDHANI jointly prepared and issued disk amnesties to Hindustan Aeronautics Limited (HAL), Bangalore, for Adour engines to power Jaguar / Hawk aircraft.
