[electronic translation] Holding “Helicopters of Russia” (part of the Rostekh State Corporation) confirmed the possibility of operating the newest multi-purpose helicopters Mi-171A2 in difficult climatic conditions at ambient temperatures up to -50 ° С. Based on the results of tests conducted in Yakutia, the operability of the main systems and airborne equipment has been proved.

Two Mi-171A2 helicopters designed by the Moscow Helicopter Plant. MLMilya (MVZ) performed 8 ground races (provide for the operation of engines without detachment from the ground) and 36 flights on special programs. Despite the fact that the air temperature dropped to -60 ° C, all systems and on-board equipment of helicopters worked properly, confirming the possibility of reliable operation of the Mi-171A2 in the harshest climatic conditions.

“The helicopters of the Mi-8/17 family deserve the reputation of unpretentious and efficient machines that are not afraid of harsh conditions.Therefore, the confirmation of the possibility of using the Mi-171A2 at ultra-low temperatures was quite expected.Only I want to thank the pilots and engineers who with honor withstood the harsh frosts and in the shortest time fulfilled the test program, “- said Andrei Boginsky, the general director of the holding company” Russian Helicopters “.

The specialists of GosNII GA, participating in the tests, especially noted the short preparation time for the Mi-171A2 for flight, the convenience of maintenance, flight and ground operation of the new helicopter, the reliable operation of the digital flight control and navigation system, the digital control and control system of the power plant regimes, and the technical condition diagnostics system. Obtained all the necessary objective data and documents for further certification and additional certification of the Mi-171A2 helicopter for a number of requirements of the certification category “A”.

“The Mi-171A2 is one of the most anticipated Russian helicopter engines, and the first four helicopters are scheduled for delivery this year, and I expect that the order book for this car will grow in the near future.” There is interest in the helicopter both in Russia and abroad ” , – said the Minister of Industry and Trade of the Russian Federation Denis Manturov.

The multi-purpose helicopter Mi-171A2 is one of the most anticipated novelties of the Russian helicopter industry, the result of the profound modernization of the Mi-8/17 helicopters. More than 80 changes were made to the design of the Mi-171A2. The helicopter is equipped with engines VK-2500PS-03 (civil version of engines mounted on combat helicopters Mi-28) with digital control system. One of the most important differences between the Mi-171A2 and the helicopters of the Mi-8/17 family is a new carrier system. The helicopter has a more efficient X-shaped steering screw and a new rotor with integral composite blades of improved aerodynamic configuration. Thus, only due to aerodynamics, the propensity of the Mi-171A2 rotor increased by more than 700 kg, which had a positive effect on the entire range of flight performance.

In August 2017, the helicopter received a Type A certificate from the Federal Air Transport Agency of the Russian Federation providing for the fulfillment of the most stringent safety requirements for civilian helicopters.
