Mi-6, which is below the photo, is a multipurpose heavy model of Soviet manufacture.The first copy of it was built by Mil Design Bureau in the fifties of the last century.His code name on the international classification of NATO sounds like a "hook."
General description
MI-6 - the helicopter, the main purpose of which is to transport heavy loads, as well as transportation to flip field (set on both sides of the board and in the center of the cargo cabin) passengers in an amount of 65 to 90 people.In addition, there is a more sanitary version of the machine, which provides for the possibility of placing in 41 patients and two medical workers in designated seats.In order to ensure transportation of bulky cargo on external sling is used winch, managed by the operator.The model is the first in the history of serial helicopter, equipped with two turboshaft powerplants with free turbine.It is impossible not to mention the fact that at the time of its creation gelikoptёr was the hoisting of the planet among such machines.When creating models of heavy helicopters in the next few years are often the basis for the design was taken exactly the Mi-6.
history of development and construction
In the early fifties of the last century by the Soviet Union there were missiles, known as the "Moon".In order to ensure their transportation state needs heavy helicopters, which were characterized by high load capacity.To develop and build such a car the Government instructed Mil design bureau.Design model was launched in late 1952.Model of the new gelikoptёra was ready a year later.After some modifications 5 June 1957 first flew on a test sample of the Mi-6.Helicopter commercially produced in factories in the cities of Rostov and Moscow.In total, these companies were built 860 of these cars made in the modification of military and civil.Most
created gelikoptёrov entered service of the Soviet Union.At the same time during the period from 1964 to 1978 model is actively exported abroad.Its main customers were India, Egypt, China, Vietnam, Iraq, Peru, Syria, and Ethiopia.In 1980, the serial production of the helicopter has been collapsed, and in 2002 stopped and the operation of the machine in our country.
design
model is based on the single-rotor scheme with the tail rotor and the wing.Passengers and cabin located under the motor and the fuel compartments.Reinforced floor is equipped with mooring sites, making gelikoptёr capable of transporting heavy loads, including military equipment.As for large objects, they are transported with the help of external suspension, capable of withstanding loads up to 8 tons.The cockpit is located in the bow.The blades of the screw shaft made of solid metal pipe.In order to prevent icing, all parts of the machine, which can suffer from this, are equipped with a special system.The model uses a chassis that rests on three pillars, and not removed.As for the wheels, they are dual front, but their orientation is carried out independently.
Key Features
Immediately after creating a model in the foreign press, a host of articles, reads that any of the giants of the West with a full load can easily raise their own helicopter Mi-6.Technical characteristics of the machine, developed over half a century ago, even today, cause a lot of positive reviews of experts.It is equipped with two engines D-25B, the design of which was developed P. Solovyov.Each of them has an output of 5,500 horsepower.Normal takeoff weight of 40.5 tons of models, while the maximum value of this indicator - 42.5 tons.Cruising speed gelikoptёra equals 250 km / h.With 8 tons of cargo on board, he is able to cover the distance of 620 kilometers.By reducing the load it is possible to refuel the internal tanks and therefore the flight range increased.The largest of its value reaches 1450 kilometers.
Achievements
On stage trials that MI-6 was held in the period from 1959 to 1963, it was established sixteen world records, to make it not only the most Carrying capacity, but also the fastest gelikoptёrom on the planet.The most significant achievement is considered to rise to a height of 5600 meters a weight of 5 tons, climbing to a height of over 2,000 meters a weight of 20 tons, the development speed of flight to the level of 340 km / h in the area 100 kilometers long and others.It should be noted that the last of these records remain in force today.Such achievements Mil Design Bureau has not gone unnoticed - for them it was awarded the international prize named after IISikorski.
most famous disaster
In the history of exploitation are the two major helicopter crash of the Mi-6.The first of these occurred in Novoagansk January 3, 1984.Then, the machine performs the transportation of passengers and cargo within the expedition on oil exploration.She failed to gain the necessary height, resulting gelikoptёr hit the ground and turned over to the left, burned down.The tragedy resulted in the deaths of 38 passengers.As the results of the investigation of this case, the cause of the incident was the excessive weight of the helicopter.
December 11, 1990 near the Belarusian town of Corbin crashed another Mi-6.The helicopter lands in very difficult weather conditions.The crew was unable to cope with the management, which has led to the achievement of a critical pitch angle.As a result, the machine crashed to the ground and caught fire.All four crew members were killed when injuries.
Interesting facts
At the design stage design model provided that its total takeoff weight should be 40 tonnes.The maximum value of this index in the foreign analogues at that time was 15 tons.
machine is the first in the USSR gelikoptёrom equipped with a gas turbine power plant.
MI-6 - a helicopter for the first time in the history of Soviet aircraft construction was brought to reality the possibility of transportation of cargo is the fuselage.
helicopters of this model have been actively involved in the aftermath of the Chernobyl disaster in 1986.
plural gelikoptёra are now at the sites of the radio equipment, because their use after participating in the above-mentioned operation would be dangerous.
Mi-62
Specific words deserves another interesting development Mil design bureau.After the Russian army appeared combat helicopter Mi-28, it received a government contract for the development of the next model.The main requirement is to put forward a novelty - a full compliance with the realities of the 21st century.Work on the project started in 2000 and lasted nearly a decade.Her result was that the light appeared a fundamentally new helicopter - the Mi-62.It works different from similar machines, issued at the beginning of this century.More specifically, the upper rotor is exclusively for take-off and landing, and to ensure that the machine has reached cruising speed, used rocket boosters AI-222-25.Each of them develops an output of 5,500 horsepower.Even in spite of the constant shortage of funds this year, the machine was adopted by the national army.
