"Rostvertol", part of the Russian Helicopters holding company "Helicopters of Russia", was the winner of the contest "100 best goods of Russia". The plant has won in the category "Products for industrial purposes" provided for export version of the Mi-26T (C). Earlier, the helicopter was awarded the regional contest "Best Goods of the Don."
Mi-26T, manufactured by JSC "Rostvertol", this unique helicopter capable of transporting up to 20 tons of cargo on the external load or inside the cargo compartment. By the right of this machine is in steady demand in the world market. The main operators of this helicopter, in addition to the Russian and CIS countries are countries such as China, India, Venezuela, Greece. Mi-26T is also frequently and successfully operates on a lease in many European, Asian and African countries.
History of creation.
The helicopter flew over the burning reactor of the Chernobyl nuclear power plant in the world’s hot spots as part of UN peacekeeping missions. It can carry loads up to 20 tons, range — 2000 km. The diameter of the helix is wingspan of a Boeing 737. It has two engines to 11000 hp capacity each.
This Mi-26 — the largest serial transport helicopter in the world!
Project heavy helicopter assigned new Mi-26 or "the product 90." Having received a positive opinion from the Scientific Research Institute of the IAP, the team "Mil Moscow. ML Mile "in August 1971 began to develop a pilot project, which was completed in three months. By this time, the military customer has made changes to the technical requirements for the helicopter — increased the maximum payload weight of 15 to 18 tons The project was redesigned.
The Mi-26, like its predecessor — the Mi-6 was intended for the transport of various types of military equipment, delivering ammunition, food, ammunition and other supplies, vnutrifrontovyh rendition divisions of troops with combat equipment and weapons, medical evacuations, and, some cases, for tactical landings.
The Mi-26 is the first home of the new third-generation helicopter. These rotorcraft developed in the late 60’s — early 70’s. many foreign firms and different from their predecessors improved technical and economic parameters, first of all transport efficiency. But the parameters of the Mi-26 were significantly superior to both domestic and foreign rates of helicopters with cargo cabin. Weight efficiency was 50% (instead of 34% of the Mi-6), fuel efficiency — 0.62 kg / (m * km). Almost at the same geometrical dimensions as that of the MI-6, the new device has twice the payload and significantly better performance characteristics. The increase in capacity is almost twice the impact on the take-off weight of the helicopter.
Scientific and Technical Council approved the preliminary design of the MAP Mi-26 in December 1971 Designing aerial giant implies a large amount of research, development and technological work, and the development of new equipment.
In 1972, the "Mil Moscow. ML Mile "has received a positive opinion institutes aviation industry and the customer. Of the two proposals presented by the Air Force Mi-26 and rotorcraft design Ukhtomskogo Helicopters — the military chose the Mil helicopters. An important step in designing the helicopter was competent drawing up the terms of reference. The customer initially required installation on a helicopter wheel drive, heavy weapons, sealing the cargo compartment, ensuring the engines for automotive fuels, and similar improvements that result in a significant increase in weight design.
Engineers have found a reasonable compromise — minor demands were rejected, and the main — are fulfilled. The result has been made new cabin layout, allowing the crew to increase from four to five persons height of cargo cabin, in contrast to the original draft, was the same throughout. Design has undergone refinements and some other parts of the helicopter.
In 1974, the face of heavy Mi-26 is almost completely formed. He had a classic for transport helicopters Mil layout: almost all of the power plant are above the truck cab, made by forward relative to the main gearbox and engines located in the forward part of the cabin crew was equilibrated with a tail. In the design of the helicopter fuselage for the first time the calculation was performed by specifying a surface curves of the second order, which all-metal semi-monocoque fuselage of the Mi-26 received its typical aerodynamically shaped "dolphin-like" shape. Its construction was originally envisaged to apply the panel assembly and kleesvarnye frame joints.
In the forward part of the fuselage was the Mi-26 crew cab with the commander (left pilot), right-pilot, navigator and borttehnika and cabin for four persons accompanying the goods, and the fifth member of the crew — flight engineer. The sides of the booths were provided hatches blisters for the emergency evacuation of the helicopter, as well as armor plates.
The central part of the fuselage occupied spacious cargo compartment with the rear compartment, passing in the tail boom. Cabin length — 12.1 m (with ladder — 15 m), width — 3.2 m, and height ranged from 2.95 to 3.17 pm As confirmed by the test layout, size cockpit allows you to carry all kinds of promising military equipment weight up to 20 tons, intended to equip the mechanized infantry divisions, such as infantry fighting vehicles, self-propelled howitzer, armored reconnaissance vehicle, etc. Loading equipment was carried out under its own power through the cargo hatch in the rear fuselage, equipped with two drop-side flaps and lowers the ladder with podtrapnikami. Management ladder and doors were hydraulically.
Loading passengers or light cargo could be made, in addition, three entrance stairs on the sides of the fuselage. In the troop Mi-26 was carrying 82 soldiers or 68 paratroopers. Special equipment allowed for a few hours to turn in a helicopter ambulance to transport 60 wounded on stretchers and three accompanying medical staff. Oversized loads weighing up to 20 tonnes can be transported on the external load. Its units were located in the design of powered floor, so did not require dismantling of the carriage of goods within the fuselage. Rear cargo door fuselage smoothly into the tail boom with a profiled end-keel beam and stabilizer.
Under the cargo floor fuselage were placed eight main fuel tanks with total capacity of 12,000 liters. In the ferry version in the cargo Mi-26 could be installed four additional tanks with total capacity of 14,800 liters. From the top, above the cargo cabin, located the engine compartment of the main gearbox and two feed fuel tanks. At the entrances to the engine intakes were installed mushroom dust filters. Supplies fuel tanks and engines were protected by armor.
The primary objective in the design of the Mi-26, as well as all other helicopters, was the creation of the modern rotor has a low weight and high aerodynamic characteristics. For the first time in the
history of highly loaded helicopter rotor Mi-26 was created vosmilopastnym. In order to collect a screw sleeve bushing had to make a detachable.
Fixing of the blades to the hub has been traditional means of three hinges, but the design of the axial pivot Engineers "MVZ. Mil "introduced torsion perceiving centrifugal loads. A number of hinge assemblies carried out with the use of metal-PTFE bearings. Vertical joints were equipped with spring-hydraulic dampers. To reduce the weight of the rotor head in its construction instead of the titanium steel was used. All this has created vosmilopastnoy rotor thrust with a 30% increase and a mass of 2 tons less than the five-blade rotor MI-6.
?Chassis MI-26 — tripod, which includes front and two main pillars, with two-chamber shock-absorbing struts. By the end beam was installed retractable tail wheel. For ease of handling the main landing gear was equipped with clearance adjustment.
Deliveries of the Mi-26 in individual transport and combat aircraft Army regiments, squadrons and regiments in frontier began in 1983 after several years of fine tuning, they have become trusted and loved ones in the military machine. Combat use of helicopters in Afghanistan began. Were part of the 23rd Regiment Border helicopters were used for transportation of goods, delivery of reinforcements and evacuate the wounded. Combat deaths were not.
Attended the Mi-26 and almost all of the armed conflicts in the Caucasus, including the two "Chechen wars". In particular, it is on the Mi-26 was carried out operational delivery of forces and their redeployment in the fighting in Dagestan in 1999 In addition to the Army Air Corps and Air Force Mi-26 border troops arrived at the time and in the air unit Russian Ministry of Internal Affairs. Everywhere helicopter proved to be extremely reliable and are often irreplaceable machine.
Have been used for the Mi-26 fighting fires, and natural disasters. In 1986, helicopters were used in the aftermath of the accident at the Chernobyl nuclear power plant.
In Aeroflot Mi-26 began arriving in 1986 received their first Tyumen airline. It was during the development of gas fields in Western Siberia is particularly handy, heavy-duty Rostov. Especially in demand were unique crane and assembly capacity machine. Only on it can be transported and installed directly to site loads weighing up to 20 tons
Happened to the Russian and Ukrainian Mi-26 to participate in the UN peacekeeping missions. They worked in the territory of the former Yugoslavia, Somalia, Cambodia, Indonesia, etc.
Due to the unique capacity, heavy-duty Rostov are in great demand abroad. There they operated the last ten years as domestic airlines, and as a part of foreign, hired helicopters to rent or lease. Mi-26T served in Germany and other European countries with heavy large cargo transportation, construction and installation work for the construction of power lines, antenna towers, reconstruction and construction of industrial facilities, and urban fighting forest fires.
— September 27, 1996 was used for the construction of a large formation, which then was entered in the Guinness Book of Records. During this event has been set yet another record, the Mi-26 lifted to a height of 6500 meters 224 parachutist.
— Used for the evacuation of two helicopters CH-47 "Chinook" of U.S. forces in Afghanistan, the $ 650,000 cost of evacuation.
— Used for the transportation of the Tu-134 from Pulkovo airport to the site near the Emergency neighborhoods Fishing in St. Petersburg.
