Russia’s latest multirole Mi-171A2 helicopter has completed trials in extremely low temperatures of up to -50 degrees Centigrade, local media reports quoting Russian Helicopters Holding’s press service.

"The results of the tests, held in Yakutia, have proven that main systems and avionics are operable [in extremely low temperatures]. Two Mi-171A2 helicopters have performed eight ground runs (when engines are switched on without taking off), and 36 flights under special programs," the company’s press service said Wednesday, TASS reports.

The tests confirmed that Mi-171A2 helicopters can operate in harshest climatic conditions.

Mi-171A2 design has 80 upgrades against the basic model, the Mi-8/Mi-17 helicopter family. The helicopter has VK-2500PS-03 engine (civilian option of engines mounted on combat Mi-28) with digital controls. Mi-171A2 is distinguished by a new carrying system against Mi-8/Mi-17 family. The helicopter has an upgraded X-shaped anti-torque rotor and the main rotor with all-composite blades of upgraded aerodynamic shape. Thus, the aerodynamic advantages increase the main rotor thrust of Mi-171A2 over 700 kg which improves all flight and technical characteristics.

Russian Industry and Trade Minister earlier described Mi-171A2 as "one of the most anticipated helicopter of the Russian helicopter industry".

In late 2017, contracts for two Mi-171A2 were signed with Indian and Kazakh companies. Another two helicopters are to be handed over in the spring of 2018 to UTair - Helicopter Services (a unit of UTair airlines) for test operations.
