The largest helicopter in the world
The helicopter was flying over the flaming Chernobyl nuclear reactor in the hot spots of the world as part of UN peacekeeping missions. It can carry loads up to 20 tons, flight range - 2000 km. Screw diameter equal to the span of the wings 737 of the aircraft. It has two engines of 11,000 liters. from. power each. This Mi-26 - the largest serial transport helicopter in the world! Airline "UTair" operates the world's largest in size and capacity of the helicopter fleet. Among the park has 352 helicopters, 25 of which - is the Mi-26.
Mi-26 - Soviet multipurpose transport helicopter. Is the world's largest serial transport helicopter. Developer - Mil. The first flight has made December 14, 1977. Serially produced by the Rostov Helicopter Plant. Total produced more than 310 machines. Issue proceeds.
Mi-26 UTair in UN livery in Surgut:
heavy helicopter project was given a new designation Mi-26 or "article 90". Having received a positive opinion from the Scientific Research Institute of the MAP, the team '' Mil. Mil '' in August 1971, began to develop a pilot project, which was completed in three months. By this time, a military customer has made changes to the technical requirements for the helicopter - has increased the weight of the maximum payload from 15 to 18 tons The project was redesigned..
The Mi-26, like its predecessor - the Mi-6, intended for transportation of various types of military equipment, delivering ammunition, food, equipment and other tangible assets, vnutrifrontovyh rendition divisions of troops with combat equipment and weapons, the evacuation of the sick and wounded and, some cases, for tactical landings.
Mi-26 is the first domestic helicopter of the new third generation. These rotorcraft were developed in the late 60's - early 70-ies. Many foreign companies and different from their predecessors improved technical and economic performance, especially transport efficiency. But the parameters of the Mi-26 were significantly superior to both domestic and foreign indices with the cargo cabin of the helicopter. Weight efficiency was 50% (instead of 34% Ni-6), fuel efficiency - 0, 62 kg / (m * km). Almost at the same geometric dimensions as that of MI-6, the new machine was twice the payload and significantly better performance characteristics. load capacity doubling almost no effect on the take-off weight of the helicopter. Scientific and Technical Council of MAP approved the preliminary design of the Mi-26 in December 1971 Design of air giant implied holding a large volume of research, development and technological work, and the development of new equipment.
In 1972, '' Mil. Mil '' has received positive conclusion of the institutions of the aviation industry and the customer. Of the two proposals submitted by the Air Force Mi-26 and rotorcraft development Ukhtomsky Helicopter Plant - military chose Mil helicopters. An important step in the design of the helicopter was well-written technical specifications. The customer initially required installation on a helicopter drive wheels, heavy weapons, sealing the cargo compartment, to operate the engines of automotive fuels and similar improvements entailing considerable weighting structure.
Engineers have found a reasonable compromise - secondary demands were rejected, and the main - made. As a result of the new layout of the cab, allowing the crew to increase from four to five people it has been made; the height of the cargo compartment, in contrast to the initial draft, became the same throughout its length. Completions undergone construction and some other parts of the helicopter.
In 1974, the appearance of a heavy Mi-26 is almost fully formed. He had a classic for Mil transport helicopters layout: almost all the systems of the power plant were above the cargo compartment; handed forward with respect to the main gearbox and engines located in the bow cabin crew equilibrated tailpiece. In the design of the helicopter fuselage for the first time calculation was performed by specifying a curved surface of the second order, so all-metal semi-monocoque fuselage of the Mi-26 received its characteristic streamlined "dolphin-like" shape. In his design originally envisaged to apply the panel assembly and the chassis kleesvarnye compound. The forward fuselage cabin crew was Mi-26 from the commander's station (left pilot), right-pilot, navigator and flight engineer, as well as the cabin for four people accompanying the goods, and the fifth member of the crew - mechanic. The sides of the cabin hatch, the blisters were provided for the emergency evacuation of the helicopter, as well as armor plate.
The central part of the fuselage occupied the spacious cargo compartment with the rear compartment, passing in the tail boom. Cabin length - 12 1 m (with a ladder - 15 m) width - 3, 2 m and the height was varied between 2, 95 and 3, 17 m As confirmed mock test cabin dimensions allowed to carry all kinds of prospective military mass art. to 20 m, intended to equip motorized division such as infantry fighting vehicle, self-propelled howitzer, armored reconnaissance vehicle, and so on. n. Loading technique implemented under its own power through a cargo door in the rear fuselage, equipped with two openable side flaps and dipping ladder with podtrapnika and. gangway and flaps control has been hydraulically.
Loading passengers or light cargo could be carried out, in addition, three entrance stairs on the fuselage sides. In the embodiment of the troop carrying the Mi-26 82 68 soldier or parachute. Special equipment allows for several hours converted into sanitary helicopter for transport 60 wounded on a stretcher and three accompanying paramedics. Oversized loads of up to 20 m can be transported on the external load. Its units were located in the floor of the power structure, so that did not require the dismantling of the system for the carriage of cargo inside the fuselage. Rear cargo hatch fuselage smoothly into the tail boom with a profiled end-beam keel and stabilizer.
Under the cargo floor of the fuselage were placed eight main fuel tanks with a total capacity of 12,000 liters. In Ferry embodiment in the cargo Mi-26 could be mounted four additional tank total capacity of 14,800 liters. On top, over the cargo compartment, placed the engine compartment, the main gearbox and the two consumable fuel tanks. The accesses to the engine air intakes were installed resp fungiform device. Expendable fuel tanks and engines were protected with armor. The primary objective in designing the Mi-26, like all other helicopters, has been the creation of modern rotor having a low mass and high aerodynamic and strength characteristics. For the first time in the history of heavy-duty helicopter Mi-26 carrying the screw created vosmilopastnym. In order to assemble such a screw bushing sleeves had to make removable.
Fixing of the blades to the hub has been traditional, by means of three hinges, but in the hinge design engineers' Mil. Mil '' entered torsion perceiving centrifugal loads. A number of hinge joints performed using PTFE-metal bearings. Vertical joints were equipped with spring-hydraulic dampers. rotor in its construction was used instead of titanium steel sleeve to reduce weight. All this has created vosmilopastnoy with a thrust bearing screw 30% more and a weight per m 2 is less than five-blade propeller Mi-6.
Chassis Mi-26 - tricycle comprising a front and two main supports, a two-chamber shock-absorbing struts. By the end beam has been installed retractable tail wheel. For ease of loading and unloading of main landing gear was equipped with a system of clearance changes.
Delivery of Mi-26 in individual transport and combat aviation regiments army, the regiments and squadrons of border troops began in 1983. After several years of refinement, they become reliable and loved ones in the armed forces vehicles. The use of helicopter gunships began in Afghanistan. Were part of the 23rd Regiment of frontier troops used helicopters for transportation of goods, delivery of replenishment and evacuation of the wounded. Combat losses were not.
Attended the Mi-26 and almost all armed conflicts in the Caucasus, including the two "Chechen" wars. In particular, it was on the Mi-26 carried operational delivery of troops and their redeployment during the fighting in Dagestan in 1999. In addition to the Army Aviation and Air Force Mi-26 border guards came at the time and in the air unit Ministry of Internal Affairs of Russia. Everywhere helicopter proved to be a very reliable and often irreplaceable machine. Have been used Mi-26 when fighting fires, and natural disasters. In 1986, helicopters were used in the aftermath of the Chernobyl accident.
The cemetery equipment near Pripyat is MI-6, the younger brothers of the Mi-26:
In Aeroflot Mi-26 began arriving in 1986 received their first Tyumen airline. It was during the development of oil and gas fields of Western Siberia is particularly useful, heavy Rostov. Especially in demand were unique crane-mounting machine capacity. Only on it can be transported and set in place directly operating loads of up to 20 m.
It happened to the Russian and Ukrainian Mi-26 to participate in the UN peacekeeping missions. They worked on the territory of the former Yugoslavia, Somalia, Cambodia, Indonesia and so on. D.
Due to the unique load capacity, heavy-duty Rostov are in great demand abroad. There they last ten years operated as the domestic airlines, and as part of foreign hired helicopters to rent or lease. Mi-26T is performed in Germany and other European countries, transportation of heavy oversized cargo, construction and installation works in the construction of power lines, antenna towers, reconstruction and construction of industrial facilities, suppression of forest and urban fires.
- September 27, 1996 was used for the construction of a large formation which was later 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.
- We used to evacuate two helicopters CH-47 "Chinook" of US forces in Afghanistan, evacuation costs $ 650,000.
- used to transport the plane Tu-134 of Pulkovo airport to the landfill MOE near neighborhoods Fishing in St. Petersburg.
