Ukrainian Motor Sich JSC told about testing new blades for helicopters


Ukraine now has its own closed production cycle for helicopters. Motor Sich JSC (Zaporozhye) gave a detailed account of the testing and production of new blades for rotary-wing aircraft, writes the Ukrainian portal Defense Express.


On December 24, 2020, factory tests of two sets of blades began at the Motor Sich flight test center. The first (metal) is for the Mi-24, and the second (composite) for the Mi-8.

The test pilots showed the various capabilities of the helicopters. To demonstrate stability, the following were demonstrated: a turn with a roll of up to 60 degrees, a "slide" maneuver and a "turn on a hill".


Nice (soft) on deep bends and during combat maneuvers. Wish this kit successfully overcomes all further trials

- said Vladimir Kolesnik, who drove the Mi-8SB.

After that, the blades themselves were presented and the details of their production were reported.

Everything that you saw today was done by the hands and brains of Ukrainian engineers, scientists and workers.

- emphasized the head of Motor Sich Vyacheslav Boguslaev.

Our blades have been calculated for strength and aerodynamics by our scientists. We are responsible for their reliability. We guarantee that their resource will be longer than that of similar blades manufactured in other countries.

- Boguslaev specified.


The chief designer of Motor Sich and the creator of new products Alexander Zherdev explained that the new blades will be cheaper than imported ones. He recalled that earlier such products were purchased in Russia and paid for them 800-900 thousand dollars per set.

We have been working towards this for 10 years. Science-intensive Technology, complex equipment, many stands, slipways. Structurally, the blades are distinguished by more advanced materials. We have about 200 engineers in the OKB, excluding production workers and technologists, who also took part in the production

- explained Zherdev.

It should be noted that the Ukrainian military showed particular interest. The APU is in great need of metal blades for the Mi-24 shock. More than 100 of these helicopters are "chained" to the ground and cannot take to the sky, as they are waiting for the replacement of the blades.

Old blades have already exhausted their resource. Helicopters don't climb on those blades today. We are already planning, and Vyacheslav Aleksandrovich (Boguslaev) promised us that in 2021 he will significantly help us to raise a serious fleet of combat helicopters into the air

- said the Commander-in-Chief of the Armed Forces of Ukraine, Colonel-General Ruslan Khomchak.

President of Ukraine Volodymyr Zelensky has already ordered to lift at least four Mi-2021 shock units with new blades into the air in 24.

However, it should be recalled that despite the interest on the part of the Armed Forces of Ukraine, only one of the stages of factory tests has passed so far, and state tests are planned for 2021. Only after that the certification will pass and the serial production will begin. But the company is already preparing a production line.

We build a line of these blades - 60 sets per year. Next year we will make 20 sets for our troops

- Boguslaev summed up.

    And what about this in other countries?

    The Russian Helicopters holding (part of the Rostec State Corporation), within the framework of the Army-2020 International Military-Technical Forum, presented one-piece composite helicopter blade a new shape that will increase the maximum speed combat helicopters of the Mi-28 and Mi-35 types.

    All Russian helicopters will receive composite blades
    As reported by Russian Helicopters, one-piece composite structures have significantly increased fatigue strength, combat survivability and resistance to external influences, their resource is many times greater than that of all-metal blades.

    As the information is contradictory and something tells me, from the Ukrainian side this is an "exaggeration" of their own achievements. Who else did he mean by "other countries" is not clear request Maybe Finland or Mongolia? Or have you surpassed your European colleagues? laughing By the way, I have not heard about the opening of the production of composites in Ukraine, if not right, I would be grateful for the information. If the blades are made from imported raw materials, then the statement that ..

    new blades will be cheaper than imported ones

    has no real ground under it. So the imitation of violent activity (IBD) and a hundred fighting helicopters will share the fate of the Lithuanians, rot on the ground and never see the sky. There is simply no money for imported composites and is not expected.

    Ukraine now has its own closed production cycle for helicopters.

    The very first phrase of the post. Did you miss the word "blades" or what? Are the helicopters going to be produced entirely? Given that the blades were mastered for 10 years with an unobvious result.

    Outright lies. But creating HB blades takes YEARS and a HUGE amount of money. First of all, we need SPECIALISTS in this area. They have never existed in Ukraine.

    They also produce mortars, they call it a "hammer", everyone remembers this infernal machine, which ukrvoenov constantly sausages itself ... they cannot assemble tanks, all Soviet / Russian wunderwafers are only repainted in blue and yellow ... blades? This product requires, let's say, good manufacturability in terms of material at least, but they can't even make metal for mortars, so ... it won't take off

    What the hell is a closed loop of helicopter production? They cannot overpower the repair of junk.
