Modifications of the Mi-171 helicopter

There is a fairly wide variety of machines of this class, which were designed and manufactured for special tasks. The most common vehicle is the Mi-171SH. It is a military transport helicopter designed to carry 16 paratroopers and military supplies. This vehicle has weapons that can destroy ground and surface targets, as well as enemy personnel. A more modern modification is considered a helicopter, which has a gas turbine power plant and a new navigation system.

The Mi-171-VA was created for work in Arctic latitudes and during flights in very difficult meteorological conditions, flights on it are possible even in the polar night. The export model Mi-171A1 has US quality certificates and fully meets all flight requirements, mainly this machine is supplied to Brazil. This machine has a significantly better safety record.

The most recent development of the Mil Design Bureau is the Mi-171A2. At the heart of this machine, the latest developments were involved and all the disadvantages of previous helicopters were taken into account. This aircraft began flight tests only in 2014.

The history of the creation of the Mi-171 helicopter

About the Mi-171 helicopter, we can say that this is a modification of the Mi-8AM helicopter, which should be exported. This machine was created in the city of Ulan-Ude with the direct support of the Mil design bureau. During the development and manufacture of the helicopter, the wishes of the customers were taken into account. This model had a power plant that bypassed its predecessor in terms of power. The Mi-171 has significantly better flight characteristics, and it is also capable of flying under difficult meteorological conditions.

As for the appearance of the machine, it is practically the same as that of the Mi-8 helicopter. But due to new and more powerful equipment, it can rise higher and has a greater lifting capacity.

The main task of the Mi-171 helicopter is to destroy both ground and surface armored objects. Fire can be produced both at immovable objects and at objects that are moving. In addition to these capabilities, the vehicle can also conduct air combat. For military purposes, it is also used to land troops and transport military equipment.

The Mi-171 helicopter can rightfully be considered an improved modification of the Mi-8 helicopter. The modernization of the machine took place at the helicopter plant in Kazan since 1977. The main changes affected almost all parts and assemblies of the device. Even the helicopter fuselage itself was lengthened, which made it possible to increase the cargo compartment. Due to this, it was possible to transport up to 29 paratroopers in full gear. The greatest changes have taken place with the onboard equipment of the vehicle.

But such a machine did not take root in practice, since the long fuselage led to large body vibrations. After modifications, the helicopter was equipped with a more powerful high-altitude power plant. The car with the new engine proved to be quite good and passed flight tests in '85.After another two years, the machine was modified, which allowed it to land at heights of up to 4 kilometers, and this machine made horizontal movement even at an altitude of 6 kilometers above sea level. All innovations and innovations have also led to an increase in flight range and climb speed.

Serial production of the Mi-171 helicopter began in early 1991. In the city of Ulan-Ude, more than a hundred such machines as the Mi-171 have already been built, and the purpose of the machines is quite different. At the end of 1997, this machine received a type certificate in the Russian Federation. This device received a type certificate according to American standards and norms in 1999 in China. This certificate confirms the quality of the cargo and passenger model of the Mi-171 helicopter both over land and over water bodies.

The most striking feature of the new machine was the more modern airframe design. The door was additionally installed on the starboard side, and the left one became much larger. The latest modification of the Mi-171 helicopter can carry significantly more soldiers, namely up to 36 people. Due to the fact that the helicopter has two doors and a cargo ramp, the paratroopers can leave the car in just 15 seconds. The maximum mass of cargo that the helicopter can carry was also increased to 4.5 tons. The nose of the aircraft has a completely new look and is more streamlined.

For more efficient power supply, the machine is equipped with a new generation of generators that do not have brushes. The latest machines of this type are equipped with excellent foreign-made navigation equipment. To achieve the best flying results, the machine is equipped with a power plant that has a capacity of 4800 horsepower. In addition, there is an additional power plant, which is manufactured in the Czech Republic.
