Mi-171А2 helicopters successfully passed tests in extremely low temperatures

The possibility of operating the newest multi-purpose helicopters Mi-171А2 in conditions of extremely low temperatures has been confirmed in Yakutia, Russian Helicopters holding reported.

Holding Helicopters of Russia (part of Rostec State Corporation) confirmed the ability to operate the latest Mi-171А2 multi-purpose helicopters in difficult climatic conditions at ambient temperatures up to —50 degrees. The performance of the main systems and on-board equipment was proved in Yakutia.

- the report says.

The press service notes that two Mi-171А2 helicopters developed by the Mil Moscow Helicopter Plant (MVZ) carried out eight ground races (involving the operation of engines off the ground) and 36 flights using special programs.

Despite the fact that the air temperature dropped to —60 degrees, all the systems and on-board equipment of the helicopters worked properly, confirming the possibility of reliable operation of the Mi-171А2 in the most severe climatic conditions

"It was informed.

According to Andrei Boginsky, Director General of the Russian Helicopters holding company, who are quoted by the press office, the confirmation of the possibility of using the Mi-171А2 at extremely low temperatures was quite expected, since "Mi-8 / 17 helicopters have earned the reputation of unpretentious and efficient machines that are not afraid of harsh conditions.

Today, in Yakutia, the sin of not experiencing the "cold" ...

I am interested in passing and the "return temperature", that is, say, in the desert, they flew at a temperature of +55 degrees in the shade! Is there any such information? ?????

This machine is designed for the Arctic. It is not practical to use it in hot countries. Although it is possible. But helicopters assembled for operation not only in the hot desert, but also in the jungle are best suited. And this “moped” should work better for what it is intended A heavy machine turned out. We are waiting for the new VK-2800. Maybe we will.

Sanchez! I sometimes take part in testing our winged ones in the North. 171A2 is not the last machine. Believe me. I proved my own. But to warm it up at -52, at least the heat and sleeves with TZ are at a maximum. TZA is the temperature start of the unit. 150 gives out for heating!

... And "150" - what kind of figure?

.. And "150" - what kind of figure? Degrees when heating VNA. Your system unit does not start even at -30. You have to adjust the machines for heating. Oil is like jelly. Heavy kerosene. Pumps cannot pump. More precisely, they pump, but they cannot ignite in engines. So far, we don’t VK-2500, and quite sensible TV-2.117

...Clear. On marine diesels, heating oil (steam / electric) in the "tanks" and before injection

Some kind of stupidity. At -40, a simple launch from the APA, that TV2-117, that TV3-117. If below heating from the MP, and then to -50 in question.

Starting from APA-5D is no problem. But at this temperature, engines and the interior are usually warming up. Gearboxes are also warming up. Running in the cold is fraught.

I will not argue. although we warmed up the engines and gearbox. With the cabin (more precisely, with the cargo compartment and crew cabin), the KO-50 did an excellent job.

Tests in Yakutia always gave an understanding of the conditions for the use of aircraft in the Arctic ...
In my memory, in the interaction between the Design Bureau and the 139th Air Detachment (Yakutsk), they tested the YAK-40, AN-72 ... this is very serious ... especially the preparation of equipment at extremely low temperatures ... take-off and landing and low-flight modes height ...

[faiver]

to us and planes and helicopters and cars are driven for verification ..

Only on the ground. In flight, the KO-50 is like a chicken bone. It only warms the cabin, it’s cold in the cabin.
