The largest helicopter in the world — the Mi-26 (PHOTOS)

The report’s author — Sergey Anashkevich (LJ aquatek_filips)

Welcome aboard the largest mass-produced helicopter in the world.
You’d be surprised, but if you put it next to the Boeing 737 airliner, it is longer! A screw diameter by as much as 4 meters longer wingspan classic series of the Boeing 737.
This flying monster can be compared to an ant. Because it is one of the few aircraft capable lift and carry cargo, almost equal in weight to himself. And not only rise, but also to transport the 20 tons of cargo to the middle of nowhere — up to 800 kilometers from the base.
Designed in the mid 70s, this goliath-workaholic is still produced in different versions — as a military transport, passenger, civil transport, flying crane, medical, etc.
310 units of the MI-26, issued over the years, operated by the military and the civil service in different countries — Russia, Kazakhstan, Ukraine, Venezuela, India, China and even in Laos and Peru.

The history of MI-26

Heavy helicopter MI-26 began to develop in the early 70’s as a replacement for the famous record holder at the time of MI-6. The need to develop a new model was conditioned as the increasing needs of the Armed Forces of the USSR and the Soviet economy. According to the requirements, the new helicopter was to carry loads of up to 20 m over a distance of 500 km, as well as hassle-free to carry out military and civilian tasks at heights of over 1,000 meters above sea level.
Heavy helicopter received the designation of a new generation Mi-26 (or "article 90") and its preliminary design was approved by the Scientific and Technical Council of the USSR MAP in December 1971 was appointed lead designer OV Bach.
The building layout Mi-26 began in 1972, and three years later it took the State Commission. By the time the final and most of the work on designing the machine. Also in 1975 a new lead designer on the Mi-26 was V.V.Shutov.
December 14, 1977 Mr. Mi-26 first flew in the air, in the sky after spending about 3 minutes. Machine operated by a crew led by leading test pilot firms G.R.Karapetyanom.
The first Mi-26 went straight into the Armed Forces of the USSR, and only after a few years began to appear civil versions of the heavyweight

2. Mi-26T helicopter, tail number RA-06031, for example, which has been prepared story today, was released on August 1, 1990. First, the company-operator acted Aeroflot USSR, where he has been for three years operated in Tyumen and Nizhnevartovsk. Then in 1993 a long 17 years helicopter was in caretaker status in Krasnoyarsk, while in 2010 was acquired by the airline UTair, which included the now operated in the Khanty-Mansi Autonomous Okrug of Russia. Place a permanent home — the airport of Surgut.

Civilian version of MI-26

3. The civil version of the helicopter, designated the Mi-26T, was launched into production January 12, 1985. Demilitarized version differed from the military counterpart primarily navigational equipment — it does not install the unit and release of LTC pivot systems for small arms. Been significantly expanded the equipment designed to improve the capabilities of the machine when working with external load.
The helicopter was equipped with an external load, which was able to transport standard shipping containers without the scaffold. Universal stabilizing platform has increased the speed of transportation of bulky and long loads (such as houses, containers, tubes) on the external load of up to 200 km / h and reduce fuel consumption by 30%. In addition, the arsenal of the Mi-26T includes automatic pipe clamps with large diameter pipes and lifters for timber transportation in mountainous areas.

4. Interestingly, even before the massive influx of the Mi-26 to the Armed Forces and the Aeroflot on it set a number of world records. For example, February 4, 1982 the crew of a test pilot flying G.V.Alferova performed in which 25 tons of cargo was able to raise the height of 4060 m and the 2,000 m helicopter took flight with a mass of 56 768.8 kg, which was also the highest international achievement. In the same year, the crew of the Mi-26, led by Irina Kopec found 9 women’s world records. When the machine is already being exploited in combat units, the military testers broke another record set by the Mi-8 in 1967 August 7, 1988 the crew of the Test Pilot 1st Class A.Razbegaeva, works by A.Lavrentiev, honored L.Danilova test navigator and flight engineer A.Burlakova passed in a closed route from Moscow to Voronezh-Kuibyshev Moscow length of 2000 km with an average speed of 279 km / h And at the final stage of the helicopter pilots had to overcome meteofront with strong turbulence and shower.

5. In Aeroflot Mi-26T began arriving in 1986, the first copy arrived in Tyumen airline after testing in State Research Institute of Civil Aviation. Initially, civil pilots retrained at the Rostov plant, and since 1987 — in Kremenchug school of civil aviation. This school received two Mi-26, which until the end of 1989 has prepared hundreds of commanders, co-pilots, navigators, flight engineers and flight operator. After the helicopters flying time between overhauls, they were directed to Konotopskiy remzavod where are today.

6. The central part of the fuselage MI-26 has a roomy cargo compartment with the rear compartment, passing in the tail boom. Cabin length — 12.1 m (with ladder — 15m), 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 weighing up to 20 tons, intended to equip the mechanized infantry division, such as infantry fighting vehicle, 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 — hydraulic.

7. 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. In the civilian version of the rear compartment allows you to carry any cargo or equipment. In addition, large loads weighing up to 20 tonnes can be transported on the external load. Its units were located in the design of powered floor, so it does not involve the removal of the carriage of goods within the fuselage.
The cargo compartment helicopter, in addition to goods, also allows for extra fuel tanks (pictured), thereby increasing the possible range of MI-26.

8. The interior of the cargo compartment is equipped with a set of equipment necessary for the placement and fixation of goods — overhead cranes, hydraulics, etc.

9. When used for civilian purposes can be v
ery useful opportunity occurred Mi-26 for the delivery of large external load. Many operations are unique, have received wide recognition in the world and the most favorable impact on the reputation of the helicopter. One of the first — transportation in winter 1986 glider Tu-124SH weighing about 18 tons with Chkalovsky airfield on the territory of the town Schyolkovo-2 performed by the crew, led by S.Sugushkinym. In 1988, the Caucasus, the Mi-26T Kremenchug school, which was piloted by Commander O.V.Marikov raised to make an emergency landing in the mountains at an altitude of 3100 m Mi-8 and took him to Tbilisi. Also known evacuation operation of the Be-12 from the scene of an emergency landing in the north of Taganrog in the Rostov region.
Conducted similar operations and abroad. So, interesting work carried out in October 1994, the crew of the Mi-26T Ukhta Civil Aviation Detachment led by A.Fateevym during an expedition to Papua New Guinea. Aviators were instructed to pull the U.S. out of the swamp, "Boston" and move it to the port of Manang. Aircraft during the Second World War, was a member of the 13th Bomb Squadron United States, was shot down by the Japanese in 1945 and made an emergency landing on the "belly" and is now destined for the Royal Australian Air Force Museum.

22. As I said at the outset, all were released more than 310 helicopters MI-26 of various modifications. Due to the unique, heavy-duty load capacity, these are in great demand both in Russia and abroad, so until now. The largest civil operator of the MI-26 is a Russian company UTair, which is composed of 25 helicopters of this brand.
