Soviet transport helicopter crane Mi-10K

The multipurpose heavy helicopter Mi-10K is a specialized crane helicopter. The Mi-10K helicopter can carry bulky cargo not only inside the fuselage, but also on the external sling. The helicopter crane is mounted a conventional cable external suspension assembly, which is designed for 8000 kg cargo. The helicopter is widely used when installing poles of power lines, filtration equipment at chemical plants, when installing radio relay towers and other construction and installation works.

Helicopters Mi-10 cranes found limited use not only in the armed forces, but also in the national economy. The versatility of the application was limited by the need to equip the cargo with counter units for hydraulic lifts. The gain from the lightweight weight of the chassis of the fuselage was negated by the length of the chassis. Anticipating these problems, the Mil Design Bureau in the 1964 year began the development of a "short-legged" modification of this helicopter. The lead designer was appointed A.A. Kh. Modification of the Mi-10K was developed specifically for construction and installation works.

Single-rotor helicopter with Mi-6 scheme: steering screw, two GTE and four-chassis. The design of the fuselage and chassis are somewhat different from its predecessor. The semi-monocoque fuselage has a two-seat cockpit in front, with an improved downward view. The bearing screw is like a Mi-6 helicopter. Structural tilt forward is reduced to 0 ° 45 '. Also the steering screw was no different. The transmission system and powerplant are the same as those of the predecessor, fuel is contained in 2 fuel tanks (total capacity 9000 liters) in front of the main landing gear on the sides of the fuselage.

Designers abandoned hydraulic grippers and external platform. Thus, the chassis height was reduced, which reduced weight and drag. Instead of cameras for control when loading and unloading, which did not justify themselves, the Mi-10K was equipped with a suspended cabin with a third set of control levers and all-round visibility. The gondola was located under the nose of the fuselage. When carrying out loading and unloading and installation work, one of the pilots goes into a suspended cabin. Sitting down facing the cargo, he was able to observe the cargo and at the same time control the helicopter. "Savings" on the racks made it possible to increase the mass of cargo transported on the external sling up to 11 tons. The bottom post provided high accuracy of assembly operations. In the 1975, all the Mi-10s were equipped with an external vibration damping and vibration system.

On the Mi-10K, the autopilot was installed, which had channels of direction, pitch, roll and height, as well as a rotor stabilizer. The autopilot was included in the control system in a differential scheme. Depending on the type and working conditions, the type of application, the number of crew members ranged from 3 to 5 people (3 pilot, flight operator and flight mechanic).

Main rotor - diameter 35 m, five-blade, with three-hinged mounting of the blades and hydraulic dampers. The blades are all-metal, rectangular shape. 20 sections consisting of a nose section with an anti-icing package and a counterweight, a tail section and an end fairing are attached to the steel one-piece tubular spar. The blades were equipped with an electric anti-icing system and a spar damage indicator. The pushing four-blade tail screw with a diameter of 6,3 m had a trapezoidal blade. The blades are wooden with a spar and steel tip, have anti-icing system and a sock trim.

The power plant - two gas turbine engine D-25V design Solovyov PA, power 5500 hp / 4045 kW. The engines operate independently, which makes it possible to fly with one engine running. Each engine has its own oil system with oil cooler and oil tank.

The chassis of the Mi-10K is a non-retractable four-bearing, truss with twin wheels and oil-air shock absorbers. The front have a lever wheel suspension. A truss guard was installed on the tail boom.

The external suspension system of the Mi-10K mounted on a special frame inside the fuselage had a lifting capacity with a cable length of less than 25 meters - 11 tons, with a length of up to 40 meters - 8 tons.

New modification created in a fairly short time. Flight tests began at GosNII GA. The first flight took place 6 September 1966 g. During the flight tests the machine was used in Leningrad for installation work and the mountains of Dagestan. Mi-10K in 1967 was presented at an aviation show in Paris. MGA in 1969, the year took the car to supply officially. Production began in the 1975 year at the Rostov helicopter plant (in just two years 17 helicopters were built, and the 4 was refitted from the Mi-10). Mi-10K used in the construction of high-rise objects and in the present. The Mi-10 and Mi-10K helicopters were used for transportation, when building drilling rigs in the oil-and-gas producing areas of the Far North and Eastern Siberia, and for unique installation work during the reconstruction and construction of industrial enterprises, significantly reducing the cost and time of work.

The Mi-10K helicopter during the reconstruction of the Gorky Automobile Plant carried out special installation work. The car lifted and laid on the roofs of three workshops in the carved openings two sloping galleries of tons of 6,2 and 7,3. If during the work they didn’t use a helicopter, then the assembly line of passenger cars had to be stopped for three months and the cranes installed directly in the workshops. With the help of the Mi-10K helicopter in Paris, the factory bridge crane with farms weighing 11 tons was dismantled.

Also, with the help of Mi-10K, a unique work was successfully completed at the Kostromskaya GRES. At the top of the 250-height pipe for meters, the Mi-10K helicopter pilots helped to install 150 tons of steel structures.

In 1980, the Ukhta division of the "flying cranes" used for the first time in world practice two helicopters simultaneously for the installation of heavy metal structures. A relay mast assembled on the ground with a length of 100 meters and a mass of 40 tons, mounted on the turn points, was raised by two Mi-10K to a vertical position. The following year, similar work was carried out in the Tyumen region.

This unique aircraft at one time played a prominent role in strengthening the position of the Soviet Union as a great helicopter power. Cost center them. M.L. Mile, having developed the Mi-10K, gained invaluable experience in the development of heavy crane helicopters.

A group of designers OKB Mil for the creation of the Mi-6 and Mi-10 received high government awards. In 1968, the State Prize was awarded to Mil M.L., Lapisov V.P., Nekrasov A.V., Leikand M.A., Solovyov P.A., Pivovarov M.N., Mazitsky V.T., Chumachenko D.M., Marinu L.N., Kalashnikov G.P., Evich I.P., Uspensky O.V.

      The Mi-10 was created as a carrier platform for an operational tactical missile system (even in the preliminary project it was clear that it would not fit into the Mi-6 cargo compartment), but after a strong-willed decision that the missile of this complex (with a nuclear warhead) should be guided , it became clear that the MGK of the complex would significantly increase and the almost completely tested helicopter as a carrier would have to be abandoned. The idea of ​​a crane helicopter came to Mikhail Leontyevich's mind during a visit to the United States, he saw how technological equipment was delivered to a skyscraper under construction with the help of a helicopter (in suspended from a helicopter) for the manufacture of some kind of structure - "why not assemble it on the ground and install it in the assembly." And then the situation is suitable with the Mi-10. I must say that the Mi-10K was a very timely machine for the USSR. However, you shouldn't worry too much about it, each Mi-26 has equipment for transporting cargo on an external sling and any of the built ones can be converted (in the field) for air crane. Now the problem is that the crew for such a crane, capable of safely performing assembly operations and having the appropriate experience, will be very difficult to "gather" in Russia.

    Here, in Western Siberia, during the development of deposits and other objects, they were used very widely. The size is really impressive, during the flight it was possible to track individual rotor blades - they were so long.

    They also fly and work. I watched the installation of the r / r tower with such a crane - an enchanting sight! All grass in the surrounding forest is combed in a radius of 500 meters like a comb. The tower was assembled using this machine of three parts during daylight hours along with transportation. From close range it looks grandiose in work!

    you look at such machines and think: the publicist M. Kalashnikov is right when in his books ("The Broken Sword of the Empire", "Back in the USSR-2", etc.) he says that by the end of the 80s a new a civilization aimed at the stars ...

    Miles Mi-10PP

    In 1966, one serial “ten” was converted into an experimental radio reconnaissance helicopter (direction finder) Mi-10GR Grebeshok. It was intended to determine the location of the transmitting radio stations, for which it was equipped with a special hanging container with dropable antennas.
    In 1970, the creation of the Mi-10PP jamming production helicopter was completed. It was intended to provide combat operations of front-line aircraft by creating interference with enemy ground radars. The machine was equipped with a ST-9000 “Step” container suspended on hydraulic grips, weighing 7125 kg. Inside it were three jamming stations “Buket”, which acted on the radar for detecting and guiding missiles, causing the illumination of indicators, and eight response-transmitting stations “Fasol” to create simulated interference (when they work in the “drift” mode on the screen of the radar operator several false labels appeared at once). In the cargo compartment of the helicopter, jobs were created for EW operators, and a power supply system was installed for equipment located in the container. In 1970–80 at the Rostov and Konotop aircraft repair plants, most military “dozens” were converted into jammers. The upgraded helicopter cost 7 million rubles - almost 6 times more expensive than the original version.
    In the 1970s a worthy occupation was found for the helicopter - he mastered a very important specialty of the radio interference director. The filling of the Steppe container included typical Soviet EW aviation stations, which, although they were capricious, but with a high level of training of ground and flight personnel, allowed them to effectively solve the tasks.
    Gradually, transport vehicles began to be sent to Rostov and Konotop, from where they returned to the troops in a new quality and with a new designation Mi-10PP. At the same time, helicopters often changed their registration. So, the only "dozen" of the 51st OGVP after re-equipment in Konotop was not in Alexandria, but in the distant Nerchinsk 112th regiment. According to the testimony of the former commander of this unit, V.K. Avdienko, one squadron included the Mi-10PP detachment. The combat training on the profile was led by the deputy. EW regiment. Helicopters carried containers suspended directly on hydraulic grips. A set of platforms was preserved, and if necessary, jammers were used for transportation.

    A set of platforms was preserved, and if necessary, jammers were used for transportation. In the spring of 1983, the next Mi-112PP (No. 10K) was supposed to arrive from Konotop in the 8680603th AFP, but on May 16 it crashed during the flight. The car was driven by the crew of Art. l-that A. A. Ilchuk. During the passage of the route section of the Orel-Kustanay, the light of the fire alarm system of one engine came on and the fire extinguishing system worked. Acting according to the instructions, the commander decided to make an emergency landing on the ground. During the run, the helicopter capsized, a reduction gear shaft was cut, and the still-running engine turned off the NWTC. The crew was not injured, but the helicopter was broken. Later, the 112th AFP received at least two Mi-10PPs over the state.
    In addition to Nerchinsk, the Mi-10PP was operated in Brandis and Kobrin, as well as in the 825th AFP, which was transferred from Sredne-Belaya to the Garov-ka-2 airfield located near Khabarovsk. According to the memoirs of an officer at the same air base. A.V. Fishing, by the mid-1980s the 825th regiment included a squadron of jammers, in which concentrated helicopters, previously armed with units located in western districts and groups of troops. Obviously, by that time all the combat-ready Mi-10PPs had been assembled on the Chinese border.
    According to reports, “dozens” were operated in the Air Force until 1989, after which they began to be written off and entered for cutting. Moreover, their individual units and systems were used as spare parts for other equipment. Thus, the special containers of the 112th AFP were transferred to the 36th Special Occupational Aviation Administration (“court” regiment of the Chita 23rd VA), where their filling was used to maintain the electronic warfare equipment of the An-12PP aircraft. Two "long-legged" Mi-10s were on display at museums in Monino and Torzhok, and one was installed on a pedestal in Garovka.
