Defence Research and Development Organisation (DRDO) has developed single crystal blades technology and supplied 60 of these blades to Hindustan Aeronautics Limited (HAL) as part of their indigenous helicopter development program for helicopter engine application.
 
Under this program DRDO will develop 300 blades  of single crystal high pressure turbine blades.
 
Helicopters used in strategic and defence applications need compact and powerful aero-engines for their reliable operation at extreme conditions.
 
To achieve this, state-of-the-art Single Crystal Blades are used.
 
Very few countries including USA, UK, France and Russia have the capability to design and manufacture such Single Crystal components.
 
Defence Minister Rajnath Singh has congratulated DRDO, HAL and the industry involved in the development of this critical technology.
