Defence Metallurgical Research Laboratory (DMRL), a lab of Defence Research and Development Organisation (DRDO) has developed an Indigenous Isothermal Forging Technology for manufacturing critical components like discs, shafts and blisks etc of Adour engine (which powers Jaguar Attack Aircraft) & Kaveri engine. With this, India joins a league of limited global engine developers which have the manufacturing capability of such critical aero engine components.
- It is a crucial technology for establishing self-reliance in aeroengine technology. The technology is generic in nature and can be tuned to develop other similar aeroengine components as well.
- Using the DMRL’s 2000 MegaTon (MT) Isothermal forge press all 5 stages of High-Pressure Compressors (HPC) discs can be built out of difficult-to-deform titanium alloy.
- For the development of the technology, DMRL partnered with agencies like MIDHANI, CEMILAC (Centre for Military Airworthiness & Certification) & DGAQA (Directorate General of Aeronautical Quality Assurance).
LAToT to MIDHANI for Bulk Production
To meet bulk production requirements, DMRL had transferred the technology to MIDHANI (Mishra Dhatu Nigam Limited), a Public Sector company through a Licensing Agreement for Technology Transfer (LAToT).
- Using the facilities at DMRL Lab in Hyderabad, DMRL & MIDHANI jointly produced and supplied disc forgings to Hindustan Aeronautics Ltd (HAL), Bengaluru for fitment to Adour Engines which power the Jaguar/Hawk Aircrafts.
