TsAGI (a part of NRC “Zhukovsky Institute”) and Kazan Helicopters jointly developed new-generation composite blades that will be used in the Ansat light multi-purpose helicopters. The activity is done under the contract with the Russian Helicopters Holding (a part of Rostec State Corporation).
TsAGI has accumulated a years-long experience of developing specialized profiles of rotors and tail rotors that exceed the world level. This experience, alongside with an innovative manufacturing technology and study of the blades’ characteristics with different methods, provided a large amount of calculations and tests. This allowed developing the helicopter’s rotor blades and tail rotor blades with enhanced aerodynamics. Combined with the new manufacturing technologies and composites, this brings Ansat into a new technology level.
Preliminary calculations show that the development will increase the maximum takeoff weight by 200 kg, reducing noise level, vibration and fuel consumption. Apart from that, climb rate will be increased, and the cruise velocity will increase by 15 kph—to 235 kph. The blades were equipped with a deicing system that would allow for flights in short-term icing conditions.
Currently, preparation activities are being performed to test the samples manufactured with the state-of-the-art technology. The results obtained with TsAGI wind tunnels will allow for comparing the aerodynamic performance of the existing and new rotorcraft rotors.
‘The new milestone has been passed within the Ansat research that TsAGI has been doing since the very start of the project. This time, the scientists focus on such a vital area as new technologies of manufacturing composite rotor blades. Their usage brings potentially many advantages. Still this is an area for prodigious amount of calculations and tests that TsAGI and Kazan Helicopters will do jointly,’ said Kirill Sypalo, Director General of TsAGI, Corresponding Member of the RAS.
Supposedly, the new blades will be used for equipping not only the delivered Ansat helicopters but also the operated ones. The flights of the helicopters with the new blades are planned for late 2023; the mass production of the blades for import-substituted rotorcraft version is to start in 2024.
