News of the project Mi-26Т2В

21
Currently Russian aviation the industry continues the serial construction of Mi-26 family helicopters, which are the largest and hoisting machines of their class. In parallel, the development of the existing project continues, leading to the emergence of new opportunities. Now a number of enterprises are working on new modifications of the helicopter with the designation Mi-26T2V. In the near future, a new type of prototype will be launched for testing, and batch production should begin shortly after.


The first reports of the modernization project with the letters “T2B” appeared in October last year. Then the press service of the holding company "Helicopters of Russia" told about the new order received from the domestic Ministry of Defense. It should be noted that the topic of modernization of existing machines and the construction of improved equipment was raised earlier, but only in the middle of autumn were the main goals and objectives of the project being developed announced.

At the heart of the concept of a new project, reportedly, is the experience of operating aircraft in the course of recent armed conflicts. First of all, the peculiarities of the ongoing operation of Russian aerospace forces in Syria were taken into account. An analysis was made of the work of military transport aviation, which showed the need for certain improvements to the existing helicopters.



According to official data, the Mi-26Т2В modernization project provides for the upgrade of a number of onboard systems and devices. First of all, the onboard complex of radio-electronic equipment will undergo refinement. According to the results of the removal of some outdated units and installation of the new helicopter will receive some special features. It is expected that the pilots will be able to fly in difficult non-oriented areas at any time of the day. In addition, it was planned to ensure the possibility of work when the enemy applied means of electronic warfare.

New reports on the Mi-26Т2В project, revealing a significant part of current plans, were published by RIA News just the other day - February 14. With reference to the official representative of "Helicopters of Russia", the news agency wrote that so far the Moscow helicopter plant to them. M.L. Mile completed the design of the new machine. On the basis of the developed design documentation, the construction of the first prototype helicopter is currently underway.

The prototype of the T2B modification carries the working designation OP-1. The construction of the machine is carried out at the Rostvertol plant (Rostov-on-Don). The prototype assembly is supposed to be completed in the second half of the current year. After completion of construction, the Mi-26Т2В OP-1 will be sent to Moscow to the plant. Mile, where they will pass all the necessary flight tests.

After completing the required checks, the new transport helicopter will go into mass production. The construction of the first production machine, the Mi-26Т2В, is scheduled for the next 2019 year. In this case, it is only a year. Quarter or month of launching construction has not yet been clarified. This is probably due to a certain complexity of the work and a possible shift in the timing of their completion.

Last fall, Russian Helicopters emphasized the purpose of the new project. It was indicated that the Mi-26Т2В helicopter is being developed on the order of the Russian Ministry of Defense and intended only for it. New modification is not export. Thus, serial machines of the latest modification at the moment will be used only by one domestic customer.

According to published data, the essence of the project under the designation "Т2В" is to replace a number of elements of onboard equipment. At the same time the airframe, power plant, screws, etc. will remain the same. The basic flight performance will not change. Installing new equipment will improve the efficiency of technology in real conditions, expand the range of tasks and, to some extent, simplify its work.

One of the main differences of the Mi-26Т2В helicopter from the techniques of the previous modifications is the modified integrated complex of onboard electronic equipment NPK-90-2. The new version of the existing and used system will provide piloting in the daylight and at night. Flight along the established route, access to a given point and landing approach can be carried out automatically.

In case of flying over an area that does not have suitable landmarks, it is proposed to equip the helicopter with a number of new navigation devices. In particular, in the recent past, the use of an improved inertial navigation system based on laser gyroscopes was mentioned. In combination with an improved autopilot, the new navigation equipment will greatly simplify the operation of equipment in difficult conditions.

Local conflicts of recent decades have clearly shown the vulnerability of helicopters to enemy air defense assets. In addition, they demonstrated the need to create and use so-called. airborne defense complexes - means of timely detection of attacks and countering used anti-aircraft weapons. The authors of the project Mi-26Т2В took into account similar factors and provided means of protection against possible shelling from the ground.

According to RIA Novosti, the required defense complex will be present on board the helicopter of a promising modification. The representative of the holding "Helicopters of Russia", quoted by the news agency, said that using such a complex helicopter can not be afraid of guided missiles with radar or infrared homing heads. However, the type of complex proposed for use was not specified.

At present, the Russian industry produces aviation airborne defense complexes of several types. In particular, the Vitebsk system is installed on helicopters of several types of different purposes. For machines of the Mi-26 family, its modification under the designation L-370E26L is intended. Depending on the configuration, the Vitebsk complex is able to counteract anti-aircraft or aircraft missiles with a thermal or radar homing head. Upon detection of radiation or a rocket launch, the complex’s equipment performs jamming that suppresses the radar homing system, or fires off false thermal targets intended to disrupt the operation of infrared systems.

The proposed upgrade affects only the onboard equipment and therefore is not associated with significant processing of the airframe, power plant, screws, etc. Thus, the upgraded Mi-26Т2В will still have an eight-blade main rotor with a diameter of 32 m with a swept area of ​​more than 800 sq.m. The length of the vehicle along the fuselage will remain at the level of the 34 m. With a maximum take-off weight of up to 56, the helicopter will be able to lift into the air 20 and cargo, both inside the cabin and on the external sling.

The serial construction of the new Mi-26Т2В will start next year and, obviously, will continue over the next few years. As follows from the available data, the duration of construction and the amount of equipment collected will be directly related to the order of the military department and, possibly, security agencies. At the same time, the exact number of helicopters required has not yet been announced. Until the publication of the volume of the future contract for mass production will have to rely only on estimates and projections.

Recall that at present in the aerospace forces of Russia there are just over four dozen basic Mi-26 helicopters. Still 10 of such cars belongs to armies of national guard. There is also information about the operation of this technique by the border troops of the Federal Security Service, but its quantity is unknown. It is unlikely that the new plans will provide for the complete replacement of all existing Mi-26 previous modifications, but there is reason to believe that the new T2B will become quite numerous and will eventually occupy a significant place in the relevant parts.

It is curious that at the moment official sources speak only about the serial construction of the Mi-26Т2В helicopters. Obviously, in the series they will have to change the technique of previous models. At the same time, the possibility of repairing and upgrading cash helicopters with bringing their condition in line with the new project has not been mentioned. This may indicate that the main customer does not intend to completely re-equip his fleet of equipment. However, it cannot be excluded that the process of repair and modernization will be launched later.

In addition to the army and power structures, the Mi-26 is operated by a number of Russian civil organizations. Such equipment is available from the Ministry of Emergency Situations and from several commercial airlines. Will they buy the updated Mi-26Т2В - it’s too early to say. The special capabilities of such helicopters associated with the installation of advanced navigation systems and the presence of an airborne defense complex may be unnecessary for operation in civilian areas.

Russian Helicopters claimed that the Mi-26Т2В project was intended for the Ministry of Defense and is not an export one. The equipment of the Mi-26 family in various quantities is operated by a dozen foreign countries, and they could show interest in the new modification. However, to the best of our knowledge, the updated T2B will be supplied only to a domestic customer. At least, in the framework of the first serial batches.

In recent decades, Russian military transport aviation has repeatedly had to work in areas of local conflicts. According to the experience of such work, the requirements for an updated version of a heavy helicopter for aerospace forces were formed. According to the latest data, not so long ago, the Moscow Helicopter Plant. M.L. Mile completed the development of the Mi-26Т2В project, which made it possible to launch the construction of the first prototype machine.

The Rostvertol plant is already building a prototype with a working designation OP-1, and in a few months will hand it over to Moscow specialists for testing. The following year, after the completion of inspections, the start of serial construction of new equipment for the Russian military department is planned, which, apparently, will continue for a certain time.

The very first version of the heavy transport helicopter Mi-26 appeared a few decades ago, but the development of the original design continues to this day. By replacing those or other units, the machine improves its characteristics and gets new features. The next project of updating the Mi-26Т2В will allow helicopters to fly in difficult conditions, as well as with less risks for themselves, passengers and cargo.

    That's interesting, but equipping the Mi-26 with a wing like the Mi-6 will improve its flight characteristics or not? And why did they immediately abandon the wing, for what reasons? Specialists, help me figure it out!

      The wing on the Mi-6 was removable, and was installed as necessary for long-distance flights. During normal work from the base, it did not cling. I think on the Mi-26, with a rotor whose efficiency is 40% higher than on the Mi-6, the concept of a removable wing has lost its relevance, and without it, now it’s less of a hassle to operate.

        Where does this information come from? The Mi-6 has been with a wing all its life, due to which it had additional lifting power at speed. He was not even considered a helicopter at all. And the maximum speed of 350 km / h speaks for itself. I only saw the Mi-6 without wings (in their places there were large latches) and these wings were removed for some reason, due to which the performance characteristics of this helicopter were underestimated. I came across such a helicopter in Afghanistan (1983-85)

          indeed, mi6 from Afghanistan came to us for repair without planes, most likely they were dismantled due to damage, mi6 came to repair and almost all cars with a 100 percent replacement of the bottom, there was no living space, after repair, the wing planes were put back on the machines

          Well then do not write nonsense! Mi-6s were both with and without a wing. The wing serves to unload the rotor in horizontal flight. It had two positions - horizontal flight and flight in self-rotation mode.

          "Where does this information come from?"
          Here is an excerpt from a 50-page technical description.




          Why, in your opinion, insert non-existent (“forbidden”, etc.) modes into such a short description? But, of course, the standard configuration was “winged” and the wing “was not necessarily” set, but removed. It was possible in the 1990s to communicate with helicopter pilots from the Khanty-Mansiysk District. According to them, at that time the wing was removed from the Mi-6 quite legally: supposedly, due to the fact that the wing resource was not synchronized with the resource of the rest of the airframe (a la blades) and the wing was removed to save on repairs.
          But with the Mi-24, I think such a trick would not have rolled.

      No, the wing will not work on the Mi-26. Just because of the eight blade screw. Inductive current too strong. So there are more cons.

    Some sources say about MI26T2 that it can be controlled by a crew of two people. Interestingly t2v will get the same ability or not? And in general, from the point of view of the specifics of the military use of mi26, is it more expedient for him to have a crew of 2 people or 4?

    "Inductive flux?" Do you mean bevel flow? If it is beveled, I’m not sure that this is the reason for rejecting the wing. It would be necessary to clarify somewhere - it became interesting to myself.

        The flow rate should be lower compared to the Mi-6 screw because the efficiency of the propeller is inversely proportional to the speed of the air stream passing through this propeller. Thus, the higher the efficiency of the propeller, the lower the flow rate. In addition, in all modes of operation of the VMG, with the exception of the hovering mode, it is necessary to take into account the very bevel of the flow, about which I wrote above. Actually, I mean, I don’t see (at first glance) obstacles to installing the wing on the Mi-26. Another question: do Mi-26 need such crutches? )))

          No more reliable way to make aerodynamics a bad luck than calling an airplane propeller, also bearing, or a helicopter tail rotor with a propeller. But this is so, by the way.
          Further, I do not know what's in your personal theory, but in reality, efficiency. more precisely, the efficiency of the propeller / rotor depends on the ratio of the thrust generated by the rotor and the power supplied to it.
          As for the inductive flow from the rotor, please excuse your fantasies and read the impulse theory of rotor thrust.

    1) You didn’t even understand what I wrote)) By the way, calculating the rotor efficiency is only a special case of calculating the ideal propeller. Accordingly, there is a so-called. impulse theory of an ideal propeller. The main rotor will again be a special case thereof. Well, okay - I'm not a fan of finding fault.
    2) I already said above that you did not understand the main conclusion of your own statement (by the way, the correct one): "the ratio of the thrust generated by the screw and the power supplied to it is efficiency." If you take V the speed with which air passes through the plane of the propeller, you get the efficiency formula: E = F / N, where N is the power transmitted by the propeller to the flow (it follows from the Euler theorem on momentum in the flow - if interested, I can write more ) is equal to F * V. Substitute in the formula E. We get E = F * F / V. Reduce the numerator / denominator and get that E = 1 / V1. Or in other words, “the efficiency of the propeller is inversely proportional to the speed of the air stream passing through the given propeller” (I wrote this in the post above).
    3) If you have questions - do not hesitate to ask))

      Propeller boy, stop raving and carry speculation.
      Here it is, the NV thrust formula for impulse theory:

      Despite the fact that the air discharge speed V2 with a screw is two times higher than the suction speed V1 in the HB rotation plane.
      Further knowing that the diameter of the NV Mi-26 32 m, with a maximum take-off weight of 56 000 kg, and for the Mi-6 35 m, with a maximum take-off weight of 44 000 kg, we get that by V2 the Mi-26 helicopter is 1,5 6 times .
      That's it, the educational program is over, go learn lessons. hi

      Yes, one more comment for the ignoramus. The calculation of the propeller is a special case of the calculation of the rotor. Because for the propeller there is only one mode, axial flow, while for the carrier there is also oblique flow.

    According to published data, the essence of the project under the designation "T2V" is to replace a number of items of onboard equipment. With this glider, power pointscrews etc. will remain the same.

    To replace the Ukrainian D-136, a new PD-26V engine will be created on the Mi-12 heavy helicopter. The successful implementation of the project to create the PD-14 base engine for equipping the MS-21-300 passenger aircraft makes it possible to create on the basis of its gas generator a whole family of engines with a thrust of 9 to 18 tons. UEC based on the PD-14 gas generator is ready to develop the PD-12V turboshaft engine for the Mi-26 helicopter. It will become the most powerful turboshaft engine in the world. We are talking about the development of an engine on a new technological base, with new materials, with improved specific characteristics, including power. UEC is awaiting the announcement of a tender for the remotorization of Mi-26 using a Russian-made engine - PD-12V.

      I think those who are talking about a replacement. And the author of the article could have misunderstood the interviewee, or when writing the article, the data was outdated - “pre-sanctioned”.
      In gas turbine engines, after all, the most important thing is a gas generator, and they take it from PD-14, which they have been messing with for a long time and, we would hope, have already more or less licked it. And the main gearbox is manufactured here.
