DMRL Supplies Single-Crystal Turbine Blades to HAL for Helicopter Engine
What happened
Defence Metallurgical Research Laboratory supplied finished single crystal high-pressure turbine blades to Hindustan Aeronautics Limited for an indigenous helicopter engine. These blades are grown as a single, continuous crystal, allowing them to survive in a gas stream hotter than the melting point of the metal used to make them.

Why it matters
The ability to manufacture these single-crystal blades is a capability historically held by only a handful of nations. This successful supply chain allows Hindustan Aeronautics Limited to advance its indigenous helicopter engine manufacturing capabilities.
