News of the Mi-28HM project
The beginning of the flight tests of an experienced Mi-28HM became known at the end of July. It is reported that on July 29 the pilots of the flight test station of the Moscow-based M.L. Mile ”(Lyubertsy) for the first time raised a new helicopter into the air. The first checks of the car were carried out in the mode of hovering at low altitude. Completion of checks on this mode with confirmation of the required characteristics made it possible to continue the tests, moving on to study the operation of the equipment on other modes. It should be noted that at the end of July the spotters managed to take several photos of the prototype helicopter both in the parking lot and in the air.
A few days after the start of flight tests, military plans were announced regarding the future of the Mi-28HM helicopters. Commander-in-Chief of the Aerospace Forces, Colonel-General Viktor Bondarev on August 5 spoke about the planned dates for the start of operation of promising technology in the army. According to the commander, the serial Mi-28HM will be commissioned at the end of 2017 of the year or a little later. Also, the commander-in-chief touched upon the topic of the technical and operational characteristics of the updated helicopter. V. Bondarev said that the new helicopter will be more convenient for pilots, as well as easier to manage.
In general, the basic characteristics have been improved, thanks to which the new helicopter has an increased engine thrust and an increased ammunition load. In addition, dual control is used, and there is also a full range of means of protection against man-portable air defense systems.
A little later, new reports appeared on the course of tests, as well as on possible export prospects for development. As it turned out, even before the completion of the tests, the attack helicopter Mi-28HM was able to interest potential customers in the face of foreign countries.
18 August edition of "News" reported that a prototype of the machine Mi-28HM recently made the first test flights, which were intended to test the operation of engines and other elements of the power plant, as well as control systems and other equipment. In addition, from an unnamed source, the publication received information about the future plans of the industry. So, it is planned to complete the tests by the end of this year, after which the experimental machine will be handed over to the armed forces. In 2017, the promising helicopter should go into series.
It is reported that already the interest in the new helicopter was shown by the Algerian armed forces. In 2014, this country has already ordered several dozen Russian attack helicopters of the Mi-28HN model and now, apparently, is considering the possibility of expanding and modernizing the fleet of such vehicles through the purchase of newer machines. However, for obvious reasons, the appearance of such a contract is a matter of the distant future. The helicopter is not yet ready for mass production and transfer of finished equipment to a domestic or foreign customer.
On August 28, the well-known BMPD blog announced the appearance of a new agreement concluded as part of the modernization of the attack helicopter and its associated systems. 15 July this year, the enterprise "Moscow helicopter plant named after ML. Mila ”published information about a new contract concluded with the Center for Scientific and Technical Services“ Dynamics ”(Zhukovsky). In accordance with this agreement, the specialists of Dynamics should develop an integrated simulator for the crews of the Mi-28HE helicopter. The contract price is 355,79 million rubles.
According to reports, the development of the Mi-28НМ project (“296 Product”) began in 2009 in the framework of the Avangard-3 development work. The task of the new project was to upgrade the existing attack helicopter Mi-28Н using new systems, components and assemblies. By replacing those or other components it was planned to improve the basic flight, combat and operational qualities of the machine. In addition, some parts of the project were associated with the simplification of the production of machinery due to the rejection of components, the delivery of which may be associated with certain problems.
As part of the modernization project, the existing glider of the helicopter is retained, however, some modifications of its design are used. As a result, both the general layout and the majority of the “old” appearance remain. However, the absence of some units and the appearance of others leads to noticeable external differences between the existing Mi-28Н and the new Mi-28НМ.
The most noticeable external difference between the two machines is the lack of an antenna for the control system of anti-tank missiles of the Ataka family. This device was previously placed on the nose of the fuselage and received a fairly large fairing, giving the helicopter a recognizable look. Due to the lack of an antenna and its fairing, the nose of the upgraded vehicle has different contours, allowing at a glance to distinguish between helicopters of two modifications.
During the upgrade, the helicopter received new engines with enhanced performance. Serial Mi-28 of existing modifications are equipped with TV3-117ВМА turboshaft engines with take-off power 2200 hp. and 2400-strong emergency mode. The main production of such products remained abroad, and in addition, the supply of the required engines is hampered by political problems. As a result, the Mi-28HM project proposed to use VK-2500П-01 / ПС engines. They differ from TV3-117ВMA with higher characteristics. In addition, these engines are produced by Russian enterprises.
VK-2500П-01 / ПС product is equipped with a modern electronic work management system, as well as is equipped with fire protection. Due to new constructive solutions, increased reliability of work in areas with hot climate and in high mountains has been ensured. Also provided superiority in performance over existing engines in its class. The engine power of VK-2500П-01 / ПС on take-off mode is 2500 hp Emergency mode allows you to get power up to 2800 hp. for 2,5 min.
Earlier it was reported that in the framework of the new project, improved blades were proposed for use as part of the rotor. By changing the design of these products, it is planned to raise the maximum flight speed by about 13%. The increase in cruising speed should be 10%.
An important feature of the "Products 296" should be the processing of a complex of onboard radio-electronic means. Thus, a standard installation of a H025 radar station is proposed with the antenna placed in a spherical nadvtulochny fairing. At the same time, as reported, when creating a new helicopter, the existing station underwent a modernization aimed at improving the main characteristics. Due to this, the updated radar H025 should improve some combat characteristics of the new helicopter in comparison with the basic modification.
Declared an increase in the number of accompanied targets and improving the accuracy of determining their coordinates. New algorithms for the operation of equipment have also been developed, and the performance of computing systems has been increased tenfold. Such improvements should significantly improve the combat capabilities of vehicles, as well as to some extent simplify its piloting.
The new project eliminates one of the main drawbacks of previous modifications of the Mi-28. Previously, only the pilot could control the machine, while the operator’s cabin had a different composition of equipment. The Mi-28HM project proposes to equip both cabins with a complete set of controls needed for piloting the machine. Thus, in the event of a pilot being hit, the operator will be able to take control and withdraw the helicopter from the dangerous area.
According to domestic press reports, the Mi-28HM project proposes a set of tools aimed at improving the safety of the crew and the machine as a whole. The latest developments in the field of various passive protective equipment mounted on equipment are used. In addition, the concern "Radioelectronic Technologies" created a new laser station suppression. When an attack is detected, this device using laser radiation should divert enemy missiles away from the helicopter.
There is information about plans to upgrade the weapons complex. The nomenclature of weapons of a modernized helicopter still must include guided and unguided missiles of various types, etc. At the same time, a decision was made to use some new systems. As already mentioned, the helicopter Mi-28HM lost the bow antenna of the radio command control of anti-tank missiles. There is information according to which it is now planned to use guided missiles guided by a laser beam. To do this, use the emitter, which is available in the composition of optical-electronic equipment. Apparently, such a change in the helicopter will lead to the need to use new types of missile weapons.
The development of the Mi-28HM project was completed no later than 2014-15, after which work began on the construction of a prototype. Last year, the company Rostvertol (Rostov-on-Don), engaged in mass production of the equipment of the Mi-28 family, built a prototype of the Mi-28НМ machine, which has the additional designation OP-1. Soon the car was transferred to the flight test station for the required checks. As follows from recent reports, until recently, an experienced Mi-28HM passed preliminary tests, and only at the end of last July for the first time took off.
By now, according to press reports, a number of flights have been performed, which allowed testing the operation of the main systems. After that, new checks should be conducted to establish the capabilities and characteristics of various components and assemblies, as well as their interactions. To conduct all the necessary tests takes some time. It is mentioned that the checks will be completed by the end of the current year, after which the experimental vehicle will be handed over to the armed forces.
Already in 2017, the Russian Helicopters Corporation is about to begin the deployment of mass production of new equipment. According to the estimates of the commander of the VKS, by the end of next year, combat units will be able to begin the development of the latest serial helicopters. In the future, the mass production and supply of the Mi-28NM will make it possible to replenish the attack helicopter fleet, adding to, and eventually replacing the equipment available in the troops. The implementation of current plans will lead to a certain increase in the combat strike potential. aviationusing newer equipment with enhanced technical, operational and combat characteristics.
