Rostec, January 23, 2018 - Russian Helicopters holding, part of Rostec State Corporation, has confirmed the possibility of operating the newest multirole Mi-171A2 helicopters in harsh climates at an ambient temperature of -50 °C.

The tests conducted in Yakutia proved operability of the main systems and avionics.

Two Mi-171A2 helicopters, designed by Mil Moscow Helicopter Plant, performed eight ground runs (providing for the engine running without liftoff) and 36 special program flights.

Despite the air temperature dropping to -60 °C, all helicopter systems and avionics functioned properly, confirming the possibility of reliable operation of Mi-171A2 in the harshest climates.

“Mi-171A2 helicopters are among the most anticipated machines of the Russian helicopter industry. The first four helicopters are scheduled to be delivered this year, and I expect the backlog for this model to increase soon. The helicopters have attracted notice both in Russia and abroad,” said Denis Manturov, Minister of Industry and Trade of the Russian Federation.

The multirole Mi-171A2 helicopter is the result of a full-scale modernization of the Mi-8/17 helicopter series.

More than 80 changes were introduced to the Mi-171A2 design, with a new carrier system being one of the major differences between Mi-171A2 and other helicopters of the Mi-8/17 series.

The helicopter has more efficient X-shaped steering screws and a new carrier with blades made of composite materials with enhanced aerodynamics. Thus, thanks to that factor only, the Mi-171A2 propeller thrust is increased by more than 700 kg.
