Check the helicopter for strength


Before handing over to the customer, each helicopter passes many different tests on the ground and in the sky. The machine must confirm that it meets the specified requirements and is ready for operation.

Test site must be at the factory that produces aviation technique. At the flight test complex of the Kazan Helicopter Plant of the Russian Helicopters holding, every finished machine gets into it.

“The helicopter is completely filled with oils, kerosene, liquids, screws are fastened, then tied, and the machine passes a complex test on the ground. And then a complex of tests in the sky, ”explains the deputy chief of the flight test complex of the Kazan Helicopter Plant, Andrei Ivanov.

The helicopter is considered ready for transfer to the client only after all the tests have been passed. What must pass the machine to be considered ready for use?

Tests allow you to determine how reliably the airframe and power plant, general and special on-board equipment of the machine function. It is during the tests that the main flight performance data of the helicopter can be obtained within the established limits, to assess how they meet the specified requirements and standards.

Factory tests are also needed in order to pre-determine the characteristics of the home, reliability and performance of the helicopter, to develop temporary recommendations for its piloting and operation.

When all the factory tests have been completed, the cars are modified according to their results, the helicopter is transferred to state tests. They determine how the characteristics of the helicopter meet the specified requirements and standards. According to the results of these tests, it becomes clear whether there are enough means of ground maintenance and equipment for the normal operation of the aircraft. Representatives from industry and industry participate in state trials. Airborne and ground-based facilities (flying laboratories and flying models, flight-modeling complexes) are used for complex testing of experimental aircraft (for strength, stalling, corkscrew and others).

State and factory tests can be combined into state joint tests, then they are carried out by a team of specialists of the customer and the performer under the guidance of the state commission.

Tests of the helicopter can last quite a long time. For example, the state joint tests of an experienced Mi-28H combat helicopter began in May 2005. In order to fully appreciate the combat properties of the helicopter, the GSI program provided for a large amount of ground work and test flights. The test commission was headed personally by the Commander-in-Chief of the Air Force.

By decision of the State Commission of the Air Force, the GSI Mi-28Н helicopter were conducted in two stages. At the first stage, a preliminary opinion was issued on the possibility of issuing an installation batch of helicopters. At the same time, the decisions of the Air Force Command formed the technical looks of the Mi-28Н helicopter, which after the completion of the first stage of the GSI, ensure that the helicopter performs combat missions for the destruction of ground targets with the main weapon system. After the second stage, the technical appearance of the machine should allow the destruction of air targets using air-to-air missiles, as well as the high survival rate of the helicopter by equipping it with electronic jamming equipment.

All helicopter systems must pass the test on the ground. And only after ground tests, you can proceed to checks in the sky. Therefore, the rise of the first production helicopter Mi-28H took place only at the end of December 2005.

The first phase of the GSI Mi-28H ended in the 2007 year. Fully tested the helicopter 26 ended December 2008 of the year. According to the results of the GSI, it was established that by flight performance, stability and controllability characteristics, capabilities of the avionics complex, the range and accuracy of the applied weapons Mi-28H generally conforms to customer specifications.

The Mi-28H “Night Hunter” helicopter was adopted by order of the President of Russia 15 in October 2009, and 27 in December 2013, by the Ministry of Defense.

At the flight test site of the Kazan Helicopter Plant, not only ready and promising machines are tested. Here, at the stand for life tests, similar to a large cell, they pass the time between failures of the system of machines that the plant produces, the Mi-8 and the Ansat. This is necessary to designate the life of the helicopter resources. The place where they are tested, fenced with a dense grid, so that parts of the machine do not fly away over long distances.

Only serious and comprehensive tests allow us to confirm that the helicopter is ready for long service in various conditions.

    New cars are great. Very good. But for me personally, the Mi-24 will probably always be a kind of "standard" of a combat attack helicopter.

    It would be nice to test the "birds" in a real combat situation in order to correct possible shortcomings and flaws, so that in the future only ideal combat vehicles would be in service soldier

      There are no ideal ones, but why the author did not say a word about the fact that the Mi-28 is being produced in Rostov, at Rostvertol, it’s strange! By the way, as far as I know. they have already sang in real actions, and have shown themselves perfectly, although, "crocodile" has not yet been canceled.

        We don’t have to think about it, but about how to activate an individual crew rescue system, the Czechs already have this feature, I think it’s worth introducing it to this pepelats, because basically they now earn from the transportation of wealthy people who want to join the air sport = this imposes a special relationship on TB

        No, this is the official layout that was submitted by the MO and approved. This show is the official premiere, so to speak.

        By October 2015, they should have already collected the flight and completed the first flights.

        The cabin, if possible, is made similar to the Yak-130 which will be planted after training on the Yak-152 training center.

    The topic is interesting, but in my opinion everything was mixed together. As an amateur, I still did not understand what kind of running-in the ser. helicopters before delivery to the customer, which are experienced. You read the article, you think: "aha, the production before delivery ...", further prototypes are woven in, the plant is added. and state. tests well, etc. It would be interesting more precisely and in more detail.

      Not run-in, but PSI (acceptance tests): 3 flights for the quality control department of the plant, 3-4 flights for the customer (equipment, motors, etc. are checked in flights). In addition, the Chief Designer’s car (usually one of a small series of three to four cars) undergoes flight tests during the TOTAL service life of this type. Something like this...

        Thank. Clear and intelligible.
        Plus a question on operating time for equipment failure.
        "Here, at the endurance test stand, similar to a large cage, the operating time between failures of a system of machines manufactured by the plant, Mi-8 and Ansat, is being carried out. This is necessary in order to set the service life of the helicopter's resources."

        This is for new or modern. equipment, or also passes already accepted for a specific model, but tech. year of release there or lot. Sorry if clumsy thought issued.

          Life tests are carried out constantly for both new and old equipment. They are necessary to confirm the resource of the main product (aircraft, helicopter ...) For example, the aircraft resource (IL-96) is 60000 flight hours at 10000 landings. Resource tests allow you to extend the operation of the aircraft during the development of the main resource (most often in flight hours, since the resource for take-off and landing is more critical), then, by the decision of the Chief Designer, according to the results of the life tests, they extend the operation of the aircraft according to the technical condition to the so-called critical conditions and failures ...

      Preliminary tests, the car passes at the plant, in Rostov, apparently in Kazan it is going through the final stage, so to speak, for the document, and flight tests, they pass "at home", I regularly see them in the sky over Rostov.

        The Rostov and Kazan plants should not be confused. There is no such thing as "preliminary tests". At the Rostov plant, the helicopter is flown in the same way as at the Kazan plant ...

      Why does the station need this rare crap of a drunk designer? What will it radically change in aerodynamics ?? Design ?? It’s very similar to trying to pack a wooden stool in a suitcase — it doesn’t fold, but I want it to fit wink
      Designers, do not feel, do not "give birth" but before the people "on their fingers" felt the matter, created in fact, on a whim, all science, created aerodynamics, brought matbase under it, rechecked, yeah, it turned out very cleverly on you, 3dizigners appeared , designers do not raise their hand to call them ... sad

      I saw Czech eraplans on the Eradrom, not bad, the built-in rescue system is very pleasing, our flyers often fly, most often on the Yak52 .. or something similar, I hate when the pilot gains altitude above the runway turns off the engine in the dive, you must probably bring a bucket of valerian to flights ... Because I think any new planes are very good, now people are drawn to the beautiful (my wife already wants to fly as a "flight attendant"), and I am a helicopter modeller, it turns out that I need to share the sky with my fair half ... laughing

      These machines are cheaper than the Ka-52, this is their main +, in general, this machine survived only thanks to ROSTVERTOL, they invested the company's profit in the work on this helicopter. At the expense of a lot of things, it is unclear what is meant. I am ashamed to admit but I like 52 more.
