“BP”: the second prototype Mi-171А2 began to pass tests

Holding "Helicopters of Russia" began flight tests of the second prototype of the newest multi-purpose helicopter Mi-171А2, reports RIA News message of the press service of the company.

“Moscow Helicopter Plant. M.L. The mile of the Russian Helicopters holding company (part of Rostec) has begun the flight tests of the second prototype of the Mi-171А2 medium multipurpose helicopter, the release says.

The press service noted that “the Mi-171А2 is a further development of the world-famous medium multipurpose machines of the Mi-8 / Mi-17 family, with improved flight performance, as well as enhanced levels of safety, comfort and autonomy.”

“The design of the second prototype helicopter fully implemented the design features of this type of helicopters, corresponding to the best foreign analogues,” the company noted.

“The power plant of the Mi-171А2 helicopter consists of VK-2500PS-03 engines equipped with a digital regulation and control system and the Safir control unit, which provides engine start-up at altitudes up to 6 thousands of meters. A thorough modernization of the commercially available Mi-8 / 17 type helicopters has undergone a carrier system. The use of composite rotor blades, upgraded swashplate and bushings made it possible to reduce the total mass of the carrier system and increase the thrust of the rotor on 700 kilograms, ”said the press service.

“The Mi-171А2 helicopter is equipped with an X-shaped tail rotor with blades made of composite materials, which provides increased helicopter controllability and noise reduction. The modernization measures allowed to increase the maximum take-off weight of the helicopter by 1 a thousand kilograms in category A and by 25% to increase the weight of the cargo carried on the external sling, which is now five tons, ”the message says.

“Another new product installed on the helicopter was the complex of the KBO-17 on-board equipment, which makes it possible to carry out flights safely at any time of the day, including in adverse weather conditions. The dashboard of the complex KBO-17 is made on the principle of a “glass cabin” with five multifunctional liquid crystal displays, ”the company said.

    So I understand that we are talking about a civilian version of the car? Well - a worthy continuation of the Mi-8 family. It will be interesting to see it in the sky at the air show in comparison with "foreign counterparts".

      Yes, I suppose - this is a civilian option, but "whatever we do - all the same in the end - a Kalashnikov assault rifle!"

      A beautiful helicopter turned out. The main thing is to maintain the reliability of the ancestor.

        Here I look at such products of our aviation industry and I think, can a "gas station" (remembering McCain's words) create such beauty?

      APU Safir, which provides engine starting at an altitude of up to 6 thousand meters

      import or what? just like a French pancake, slipped all the same ...

    Application of composite rotor blades

    If new materials on breakthrough technologies are used, then one can count on high competitive characteristics for the foreign market, which is encouraging.

    Mi 8 - 17 - 171 is a kind of "Dakota" among helicopters. Such a successful car, it just hit the point of maximum demand. And do not look for "good from good." This car, as it turned out, has a huge modernization potential.

      Eugene, I’m with both hands for the content of the article and for your comment, but one thing that bothers me is the phrase
      Russian Helicopters Holding launched flight tests of the second prototype of the latest Mi-171A2 multi-purpose helicopter

      Why is this an exaggeration about the latest, why just do not talk about a new, advanced modernization of a successful model? request
      Will she get worse from this? No, it won’t, in my opinion it’s just a kind of self-praise. By the way, apart from us, serious foreign companies do not suffer similar ambitions.
      Something like that, I think subjectively. hi

      In fact, the reassembled Mi-8, no matter what.

      Well ..... what’s wrong with that? Ohhhhrennuyu design, the modernization potential which to this day they CAN’t exhaust !!! Like the machine of Grandfather Misha.

    and here the case was redone for innovation.

    Along with the construction of completely new machines, it is necessary to upgrade existing ones. And preferably not on the basis of the parent company, but on the basis of regional certified factories.

    It is clear that MI8 is a good mana, and therefore for some time they will be engaged in external / internal tuning by analogy with the VAZ penny, which has transformed through a three-ruble note into six, or five into seven. Interesting factory workers do not plan to surprise a truly new machine?

    I believe in our MI-8, it's a great car. I rejoice at the success of our developers and my soul for them.
    This helicopter is a kind of "Kalashnikov assault rifle" in its class. HO ... !!!

    We would change his "face", by God, so that it would look modern against the background of all sorts of Bell, Airbus.
    Well, there "muzzle" from the 60s practically unchanged, well, it looks, respectively, like a car of the 60s.
    To him and the attitude of buyers as a CART. I would say that this is a "loaf" among helicopters.

    Experienced people are well aware that the filling has been upgraded more than once and there is little left of the first model of the 60s.
    This product is really high-tech.
    Well reflect these changes in appearance! Show everyone, even amateurs, that you have stepped far forward!
    This is a market! It is necessary that the goods delight the buyer, so that the buyer is suitable and boasts to everyone that he has a great car.
    In order not to be shy, they shot a car in commercials and Hollywood films.
    Well this is prestige, reputation. This will only have a benign effect on sales.

    Well, it’s hard to hire a normal designer and slightly redo the front end so that the car isn’t just there,
    but also looked high-tech, beautiful and modern. This is a purely cosmetic operation, not technical - not expensive.

    By God I do not understand our aircraft manufacturers.
    Turn over a huge layer of work, technically seriously upgrade the helicopter, but do not take the smallest last step.

    The modernization potential of the MI-8 is still very high and today is far from exhausted: the capabilities of new engines, avionics, the introduction of new control systems, the creation of a variant with a quickly replaceable payload module as a standard container, with an airtight cabin, the revival of the sea variant.
    Design in aviation is always a compromise between functionality and the laws of aerodynamics. The first dictates the shape of the brick, the second drops. The lower the operating speed (for example: helicopters for installation work), the less aerodynamic requirements.
    Next-generation production will require comprehensive fundamental work from evaluating new materials in all respects to introducing new assembly principles and erecting a new plant.

    The general director of the state corporation "Rostec" Sergei Chemezov explained the appointment of former Defense Minister Anatoly Serdyukov, dismissed due to a corruption scandal, to the post of industrial director of "Rostec" for the aviation industry. According to Chemezov, the appointment of Serdyukov is an internal matter of the state corporation, which is not obliged to agree with the president and prime minister. Here is the full article

    In addition to engines and electronics, this carrier system (titanium bushing, blades and H-shaped tail rotor) from Mi 28. There is one body and remained from Mi 8.
