In a major technological breakthrough, the Defence Research and Development Organisation (DRDO) recently developed single crystal blade technology and it has supplied 60 of them to the Hindustan Aeronautics Limited (HAL) for the company’s indigenous helicopter development program for helicopter engine application.

About:

  • It is part of a programme taken up by the Defence Metallurgical Research Laboratory (DMRL), a laboratory of the DRDO.
  • The DRDO will develop total five sets 300 in number, of single crystal high pressure turbine (HPT) blades using a nickel-based super alloy.
  • They supply of other 4 sets will be completed in due course.
  • This single crystal blades technology has been developed by the Defence Metallurgical Research Laboratory (DMRL), one of the DRDO’s laboratories.
  • A few countries such as the US, the UK, France and Russia have the capability to design and manufacture single crystal components.

What is the use of single crystal blades in helicopters?

Helicopters need compact and powerful aero-engines for operating at extreme conditions and as single crystal blades have complex shape and geometry and are manufactured out of nickel-based superalloys, they are capable of withstanding high temperatures.
