The Defense Research and Development Organization (DRDO) has developed a single technology for crystal blades using nickle based superalloy for helicopters.
The Defense Research and Development Organization (DRDO) has developed a single crystal blade technology for helicopters and has provided 60 blades to Hindustan Aeronautics Limited (HAL) as part of their helicopter development program for engine use.
This is part of a program developed by the Defense Metallurgical Research Laboratory (DMRL) to make five sets of crystal high-pressure turbine (HPT) sheets using nickel-based superalloy.
Helicopters used in strategic and defense systems require integrated and powerful engines to operate in extreme conditions. To achieve this, crystal blades single state-of-the-art crystals with sophisticated geometry and geometry, produced without nickel-based superalloys are able to withstand high operating temperatures. Very few countries in the world like the US, UK, France and Russia have the ability to design and manufacture these things.
According to the DMRL, “Complete the process of dispersing the investment to detect blades, including mortar formation, wax formation, ceramic molding, actual removal of non-corrosive test components (NDE), heat treatment and size measurements have been established at DMRL “.
