Using this technology, it has produced 60 blades and supplied them to Hindustan Aeronautics Limited (HAL).

  • The technology will help in the production of blades that are capable of withstanding high temperatures of operation, which are vital for helicopters for their performance in extreme conditions.
  • HAL will use the technology for its indigenous helicopter development program.
  • Very few countries in the world such as the USA, UK, France and Russia have the capacity to design and manufacture such Single Crystal (SX) components.

Key Points

  • The blades will be developed using a nickel-based superalloy, which is capable of withstanding high temperatures.
  • The technology has been developed by DRDO as part of a program taken by Defence Metallurgical Research Laboratory (DMRL), a laboratory of DRDO.
  • The supply of 60 single crystal High-Pressure Turbine (HPT) blades is part of the deal of supplying 300 HPT blades to HAL.
