The history of the MI-8 helicopter began in the USSR. For the first time, it was developed in the early 60s. That he is the most massive two-engine helicopter, not only in Russia but throughout the world. The main purpose of this flying machine is various combat and civil operations.
After all, thanks to its technical and flight characteristics, this aircraft has earned its prestige among many Air Force of the world. Due to the wide range of possibilities of using this helicopter, its serial production began back in 1967. And, despite the rich history, today it is used in flights no less actively. Moreover, it is worth noting that this helicopter is actively being purchased by foreign countries as well.
Due to the good speed and technical characteristics, its design modifications are very active today. In conjunction with good flight range, the MI-8 model is one of the highest priority flying machines for its further improvements. Thus, MI-8 definitely occupies an honorable place in our aviation industry.
Modifications helicopter MI-8
In all the years of history, after the release of the first prototype, many different modifications of this flying machine were produced. Moreover, each of these modifications was intended to fulfill certain goals. All possible variations of helicopter models were supplied with a variety of equipment, depending on the purpose of the application. All models of this helicopter can be divided into several types:
- Experienced. The first samples, both the MI-8 itself and its modifications. In other words, these are different models of this helicopter, in which they made some changes.
- Passenger. From the name it is clear that these models of helicopters are used to transport passengers. Moreover, we are talking about both civilians and the military. In both cases, it can accommodate 18-30 people, depending on the modification, which makes it very attractive for this purpose.
- Transport. MI-8 is capable of carrying a cargo with a total weight of up to 4 tons. Not many helicopters can boast such characteristics. And because of the possibility of using it to perform multi-purpose tasks, it is completely out of competition.
- Multipurpose. In addition to all the above methods of use, MI-8 is able to perform another series of different combat missions. A good example of this is the installation of anti-personnel mines in the amount of up to 200 pieces. In some cases, they are used to perform a number of technical and repair work, thanks to special equipment. There are known cases of using MI-8 and in search and rescue operations. Sometimes, it is used as an air hospital, again, using special equipment.
Separately, it is worth noting one of the newest versions of the MI-8 helicopter, which was designed literally at the end of last year - MI-8MTV-5. It was this modification that was originally developed for the purpose of conducting combat operations in the most diverse climatic conditions. In contrast to the old models, they introduced the possibility of transporting bulky cargo by attaching to the external suspension of the helicopter. And thanks to its combat and speed characteristics, the new version of the helicopter had the opportunity to conduct fire support for the Allied infantry. Moreover, it is precisely thanks to the latest equipment that it is not at all necessary to maintain fire support in daytime conditions.
And if this model shows itself well in combat conditions, then it will definitely be accepted for permanent armament. And to have such a reliable and effective equipment for any country is very important. After all, it is thanks to her that the security of the entire state is ensured.
The design of the helicopter MI-8
MI-8 belongs to the class of single-rotor helicopters. It has five rotors and three tail rotors. Blades of the screw, made of solid metal, have a full spar created from aluminum alloys, pressed together. In addition, all the blades of the helicopter have an alarm, and in case of damage to any of the blades, the pilots will be immediately notified.
Due to the presence of two engines, in case of failure of one of them, the second automatically increases the power supplied by using modern equipment. What allows not to lose speed and maneuverability in case of faults. And this is an indisputable advantage, among other helicopters of a similar model.
In some versions of the helicopter MI-8 used specialized armored cabin. Often, such modifications are used in combat models. And such variations are very often acquired by various countries.
The chassis design has static wheel bearings in the amount of three pieces. That allows the helicopter to land even in the most inaccessible places. This is its undoubted advantage.
In addition, the helicopter installed one of the best antifreeze systems. It is she who does not let the helicopter freeze. Due to this, it can be used even in the most extreme conditions.
The helicopter MI-8 is an excellent heating and ventilation system. It allows you to heat or cool not only the cockpit, but also the passenger compartment, which makes all flights very comfortable. In addition, this system also works on the front windows of the helicopter and air intakes.
The MI-8 helicopter has a rather serious e-filling. And she, in turn, has completely different characteristics and purpose. But precisely because of it, the helicopter has its own distinctive features.
It is worth noting that in themselves the flight characteristics of the helicopter are very attractive. The good speed, along with its lifting and passenger functions, makes it a favorite among similar single-rotor helicopters. Despite the fact that the very first model was developed relatively long ago, its modifications are very actively developed to this day.
