The blades were tested as part of the flying laboratory of a new high-speed helicopter concept. "During the testing, the flying laboratory based on Mi-24 helicopter equipped with a set of new blades, reached a speed of more than 400 km/h without the need to change the base helicopter design. At the same time, we managed to maintain low vibration and load levels, which speaks of the high potential of this design," remarked Director General of Russian Helicopters, Andrey Boginsky.

The new rotor blades are currently undergoing factory flight tests on a Mi-28N helicopter.
