Russian Helicopters completes Mi-171Е2 testing
Russian Helicopters has completed testing of the Mi-171E2 helicopter with a new power unit and rotor system, the company announced on 7 February.
Designed for air transportation, the Mi-171Е2 has been developed by the Mil Moscow Helicopter Plant and will be produced in lots at the Ulan-Ude Aviation Plant (UUAP).
The testing included a total of 45 flying and non-flying stages for a total of 50 hours. The tests confirmed improved performance characteristics including increased operating efficiency at high altitudes, carrying capacity, maximum and cruising speed, climbing ability, directional control reserve, and the reduction of noise level caused by main and tail rotors.
The helicopter also has a considerable increase in the main rotor thrust, an improvement in controllability and manoeuvrability, and significant power reserve in various flight modes.
The Mi-171Е2 features an upgraded body, modified tail and keel beams and a larger stabiliser. It has VK-2500PS-03 engines with improved power and FADEC digital control system, as well as new main rotor made of polymeric composite materials with improved profile and an Х-shaped tail rotor.
The new Mi-171Е2 will be exported under the name Mi-171Е.
