Aviation the plant of the city of Ulan-Ude is preparing for testing another prototype of the Mi-171A2 helicopter - the latest representative of the Mi-171 family of helicopters. This is the fifth prototype of the Mi-171A2 helicopter. Tests, according to the press service of the Russian Helicopters concern, will make it possible to bring the state of a rotorcraft to a state of airworthiness. The next step should be the stage of the certification test program.


It is noted that the first and second prototypes have already passed the necessary tests in November 2014 and October 2015, respectively. An experimental laboratory based on the Mi-8 / 17 was also involved in the tests. Prototypes with numbers 3 and 4 did not pass flight tests, since they are bench tests.

The press service reports that the fifth prototype of the Mi-171А2 installs the main rotor and tail rotor blades, as well as equip the cabin of the helicopter and the cockpit.

The 5 th prototype of the medium multipurpose helicopter Mi-171А2 is being prepared for flight tests


Certification of the medium multipurpose helicopter Mi-171А2 should take place in the first quarter of the year 2017.

From the materials of the concern "Helicopters of Russia":
The Mi-171А2 is the newest member of the Mi-8 / 17 helicopter family that embodies the best features of these world-famous cars. The helicopter is equipped with an integrated digital flight-navigation complex onboard equipment KBO-17 ("glass cabin"), which allows you to operate the machine without the presence of an engineer on board, thereby reducing the number of crew members to two people.

A thorough modernization of the commercially available Mi-8 / 17 type helicopters has undergone a carrier system. The Mi-171А2 has received a carrier and an X-shaped tail rotor made of composite materials, as well as an improved skew machine and a sleeve for the carrier mechanism. The innovations allowed improving helicopter controllability, reducing the total mass of the carrier system and increasing the rotor thrust by 700 kg. In addition, the performance of cruising and maximum speed increased by 20%, as well as increased flight range.

    Why do we call airplanes and helicopters with old gliders "new"?

      Because you can’t come up with anything fundamentally new in the glider, look at the car, all the same elements haven’t come up with anything fundamentally new in the body. All pulp in the electronic filling and materials from which the glider and the nodes are made.

        Why are the wheels round? so much time has passed, it’s already possible to come up with something

        People what can I do here. They take the old and change closer to the TTX ideal, but do not take and do not make a new one

          Nobody says about the wheels - "a new wheel has been released."

        nevertheless, each new car has a new body, which makes it not only beautiful, but also taking into account aerodynamics. Otherwise, everyone would have continued to drive Rusbalts with a new filling. What was bad about "Victory"? The same rounded, streamlined shape as modern cars.

      Because everything is new there, except for the form of a glider bully

      But what about the new glider? Helicopters do not participate in the beauty contest. They upgraded the launch, installed a new dviglo - a new helicopter. Because it flies differently, it works differently, and the performance characteristics are different.

    Even my heart skipped a beat until it realized that it was the Mi 17th, although I respect this car, the first thought came that it was the new high-speed one. For Mi 17, the work is the same.

    Now they are privatizing Russian Helicopters, then we will rejoice. Especially if the UAE gets a large block of shares, as some media write.

    By the way, Ulan-Ude is releasing MI-17, it seems with a different "muzzle."
    Here are the recent acquisitions in Shymkent. Mi 171Sh. Ulan-Ude.

    These are helicopters with a carrier system from MI-28/38. The helicopter is undeniably good, only it will slow down the progress of MI-38. The characteristics are generally similar, but the prices are different. In this case, the best enemy of the good! We need to competently change the generation of helicopters on the assembly line. The line will probably look:
    Easy-Ansat, Ka-226
    Medium -Ka-60/62
    Medium + Mi-38 / Ka 32
    Heavy Mi-26 / promising heavy

    The most popular here are Light and medium

      Well, yes, Mi-8/17 not long ago, our emergency announced the price of 8-9 lyamov killed raccoons.
      So 8/17 will exist and be modernized for a long time. Really "workhorse" than ECcopters 725 from 11 Euros! But damn it is quieter.
