Our country was originally not attached too great importance to the establishment of the helicopters. What was the reason, now it is hard to figure out, but the fact remains: initially, the red army received only the aircraft, but nothing of the economy and can not speak.

mi 8This is despite the fact that the future development in this area was, so what! Fortunately, soon, the young country realized the fallacy of such a strategy, but because the industry began to master the production of helicopters.

The First of these was Mi-1, production of which began only in 1948. Since then and until the end of production of the Mi-4 helicopters in the country was equipped with a rotary-piston engine. In those days it was normal, but the need for the car with the best characteristics of the power plant became apparent very quickly.

New helicopter

But because by the 1960's the helicopter industry and the crucial KB of a country got the job. The result was the development of the Mi-8 helicopter, which has become a true legend of the industry, continuing to be actively used in the national economy and the armies of the world.

History

Initially it was assumed that the helicopter will be produced in the transport, passenger and commercial versions. Development began in the first months of 1960. As you might guess, had CDB Mil. For was based on the well-proven Mi-4. In fact, the new Mi-8 was originally planned as a project of deep modernization.

However, very soon the designers realized the necessity of introduction into the machine of a new type of engine, and therefore from its predecessor in this project were not so much.

The Work was carried out accelerated pace. In mid 1961 the first prototype with four blades and a single engine rose into the air. A prototype with five blades and two power plants flew through the year. At the end of the same 1962 was created the first prototype.

The Commission the characteristics of the future Mi-8 really liked it, but because in just a few years of the new helicopters has already gone into production. Since 1965, the model produced in Kazan and Ulan-Ude.

MI-8: features

Its predecessor, the new machine is 2.5 times faster than the carrying capacity. Maximum speed was also almost two times higher.

mi 8The Transmission was largely left without any significant changes. The scheme of a helicopter – single screw, but it involves the tail rotor. The design uses two gas turbine engine, the chassis rests on three wheels. In General, the Mi-8 for its time in many respects was the best model.

Of Course, for some parameters it was missed by the American “Sikorski”, but it was significantly cheaper, but had a greater carrying capacity and reliability.

Unlike the previous model, the design of the blades has been significantly revised. Appeared hollow spar, made entirely of high strength aluminum alloy. To keep the system as safe as possible, the blades are equipped with special pneumatic signal system that allows you to register mechanical damage of the spar.

Why the helicopter became so popular worldwide?

mi 8 engineIt Happened because of the simplicity and reliability of the machine. Not only in our country, its respectful styled “workhorse”. In this world – the most (!) common transport helicopter. Abroad it is known as the Mi-17, a number of them used as military helicopters (photo is in the article) the NATO contingent in Afghanistan. In connection with the usability, you do not want to spend a lot of time on training pilots.

The world is no more civil transport helicopters, which were produced in this volume: even at the old data from the conveyor descended more than 12 thousand of these machines. And it – without some modifications!

By the Way, the number of varieties of this helicopter is by far the world leader. At the moment, even the experts can't say how many versions have been created. The definition of this figure is greatly hampered by the fact that some improvements almost commercially made directly in military units, but patents for their inventions has not received, and therefore in industrial production, they have not got.

Control System and engines

helicopter mi-8 photoThe control system at this time was based on the qualitative and powerful hydraulic actuators. In addition, the Mi-8 was first used latest warning system icing, which allowed the use of a helicopter in various conditions. In addition, there was a special mechanism to secure the load, making it possible to transport by air additional three tons.

If one engine during the flight fails, the second at the same instant starts to work in forced mode, giving the capacity sufficient at least to abort the flight. To pilots were more comfortable to work in challenging conditions, the machine is equipped with an advanced autopilot that can take a significant portion of human functions.

With the latest at the time navigation andradar instrument flying on the helicopter was possible at any time of day and year. This feature quickly appreciated by the military. Moreover, one of the symbols of the national army quickly became the Mi-8 helicopter has proven to be extremely reliable and inexpensive, and therefore instantly was adopted.

What your options are used?

As we said originally, this model was built for cargo and passenger (up to 28 people) needs. In addition, in Kazan special order also produce Deluxe copies in seven persons, which are very popular among top officials and rich businessmen.

Military modifications and further development

military helicoptersWe have also mentioned in the article that the military really liked the Mi-8. Its engine was extremely reliable, in case of failure of one power plant to bring the car in, and load capacity is quite impressive.

So very soon there will be plenty of modifications of this helicopter, specially designed for military use. Most often, just undertake a transport option, to which was added the pylons for the mounting of bombs or tanks with an incendiary mix. Very soon it turned out that for the army, even this gain is not enough, and therefore any modification 8TV, equipped with the strengthened and improved suspensions. Was added the possibility of attaching the missile.

Transport-combat helicopters

Modification 8MT was a logical and final on the way to the creation of a new family of combat vehicles. The main feature was the installation of new power plants TVZ-117 MT, equipped with the latest gas turbine AI-9V. The helicopter has become much safer, as the intakes have closed the new screen that much better filtered supplied to the engine air.

To the Mi-8 helicopter, a photo of which is presented in the article could not easily knock down by heat-seeking missiles, has developed a system of dissipating the hot exhaust gases from the engine. In addition, there are mechanisms for hunting decoys. Between 1979 and 1989, the helicopter went through the whole conflict in Afghanistan.

Military and peaceful use experience

During the period, while the Soviet troops were in the country, the pilots flew hundreds of thousands of sorties. They transported millions of tons of cargo, evacuated thousands of soldiers from under the nose of the spooks. During all this time the cases of failures of the machine can be counted on the fingers.

In contrast to its "older brother" of the Mi-24, “eight” initially devoid of heavy booking, but because she always had a flight of traction even in highly rarefied mountain air.

In both Chechen conflicts, military helicopters of this type also showed themselves from the best side. Reliable and very robust, they helped not only by troops, but also MOE and ‘Red cross", who worked with the civilian population, providing it with medicines and food.

The Disaster

Unfortunately, even the higher reliability and simplicity of construction do not save military helicopters of the MI and their civilian variants of the drops.

mi 8 helicopterLet's Start with the fact that during the Afghan and Chechen conflicts, both had lost about 50-60 cars. In Afghanistan, casualties among them mainly non-combat, often associated with attacks on military airfields. It is believed that if it was lost no more than ten units of this equipment. Accurate data on casualties during the First Chechen campaign no. The Second was shot down 29 helicopters of this type.

The Advent of peaceful times, did not bring peace. As a result of technical faults, poor quality fuel and a high level of wear mechanisms in 90-e years has fallen or missing (in Siberia) more than 174 machines.

Give specific information for the years 2012-2013. So, July 14, 2013 the crew of the helicopter in the air felt that both engines began to work unstable. It was decided to put the machine directly on the peat. However, the helicopter rolled over on its side, but otherwise an emergency landing was performed perfectly. No one was killed, the wounded was not. 11 July of the same year something similar happened and in the Amur region. Then also managed to do without victims.

Unfortunately, July 2 in Yakutia as a result of falling car killed 24 people, with more than half – children. Survived only two crew members and one passenger. 6 may and 6 June of the same year was recorded the disaster of these helicopters in the Khabarovsk territory. Survivors also was not.

In 2012, the helicopters fell seven times, but killed only one person.

Of Course, it figures only for our country. How many crashed the same Mi-17 in Afghanistan, it is impossible to say, since local government rarely conducts any detailed statistics. The same can be said about the incidents in Africa.
