New helicopter blades developed by Russian Helicopters promise to increase the seed of their popular Mi-28, Mi-35 combat helicopters from the current 250kmph – 280kmph to 400kmph.
The blades were presented by the company at the ongoing Army-2020 Forum. They possess modern aerodynamic characteristics and elastic composition; and are manufactured using the technology of one-stage compression molding.
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.
