Helicopter Mi-171. A photo. Characteristics. History.


Soviet designers developed a helicopter for civil and transport, called Mi-171. There was also a modification designed for the Russian Air Force. The military version of the Mi-171 had a very widespread use in various combat missions.

The history of the helicopter Mi-171

About Mi-171 can say that it is a modification of the Mi-8AM, which should come on exports. This machine has been created in the city of Ulan-Ude in the direct support of Mil design bureau. In the development and manufacture of the helicopter were taken into account the wishes of customers. In this model was powerplant, which avoided the power of its predecessor. Mi-171 has significantly better performance characteristics, and it is able to operate under difficult weather conditions.

With regard to the appearance of the machine, it is almost the same as and Mi-8. But due to new and more powerful hardware, he can rise above and has a greater lifting capacity.

The main objective of the Mi-171 is the destruction of armored targets both ground and surface. Fire can produce both real objects and on objects that move. In addition to these capabilities, the machine can maintain and dogfight. The military uses it is also used for the landing and transportation of military equipment.

Mi-171 rightly be regarded as an improved modification of the Mi-8. Upgrading the machine was held at Kazan Helicopter Plant to 1977 years. Major changes have affected almost all of the machine parts and assemblies. Even the helicopter fuselage was lengthened, which increased cargo bay. In this way it was possible to carry up to 29 paratroopers in full gear. The greatest changes occurred with the on-board equipment of the machine.

But such a machine did not get used to practice, as the long fuselage led to large body vibrations. After completion of the helicopter equipped with a more powerful high-altitude power plant. The car with the new engine proved itself quite well and passed flight tests in 85 year. After another two years the car was modified, which allowed it to land at altitudes up to 4 kilometers, and the horizontal movement of this car produced 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 release of a helicopter Mi-171 brand began in the early 1991goda. In the city of Ulan-Ude built more than a hundred such cars as the Mi-171, and the appointment of machines quite different. At the end of this year 1997 the car has received type certification in the Russian Federation. Type Certificate by American standards and regulations, this unit received 99 in China. This certificate confirms the quality of cargo and passenger models of the Mi-171 both over land and over water bodies.

The most obvious difference between the new machines became more modern airframe design. The door was additionally installed on the starboard side, and the left has become significantly more. Last modification of the Mi-171 can carry significantly more fighters, and it is up to 36 people. Due to the fact that the helicopter has a two-door and cargo ramp, the paratroopers could leave the car in just 15 seconds. Also, the maximum weight of goods was increased, which can carry a helicopter to 4,5 tons. The nose of the vehicle has a completely new look, and it is more streamlined.

To better ensure power machine is equipped with a new generation of generators, in which there are no brushes. The last car of this type are equipped with superb navigation equipment of foreign manufacture. For best results of the flight machine is equipped with a power plant, which has a capacity of 4800 horsepower. In addition, there is an additional power unit, which is manufactured in the Czech Republic.

Design features of the Mi-171

Fighting machine Mi-171 is an air of the new generation device, which incorporates the most positive features of the previous models of military helicopters of this type. To effectively carry out combat missions, the helicopter is equipped with a whole variety of weapons complex. By the combat power of the machine guns and missiles are installed on it. In addition, the helicopter is equipped with an active protection system.

The machine has a large arsenal of equipment to carry out special missions. Due to modern equipment military operations in the Mi-171 helicopter can be performed at any time of day and in all weather conditions. The advantage of this model is the fact that it can be used in all climatic zones of our planet.

In order to convert the standard Mi-Mi-8AM in 171 helicopter does not need a lot of time. This can be achieved directly before the flight, depending on the task.

The landing model of the helicopter has the ability to transport up to 16 fighters or cargo weighing up to 4 tons. It should be noted that the transportation can be carried out both inside the cargo cabin, and on the external suspension of the machine. Sanitary version allows you to transport 12 wounded soldiers on stretchers and accompanying medics. To carry out rescue operations, the helicopter is equipped with a winch with an arrow, with which it is possible to lift loads weighing 150 kilograms. For assault landing on a helicopter, a SU-R system is installed, with which fighters can leave the car when it hangs in the air above the ground.

Due to the established helicopter EVU system that provides shielding the exhaust, the car has a large combat survivability. The helicopter is also equipped with an automatic discharge system of reflectors. Mi-171 has armor plates provided, which can be removed in case of uselessness. On hauls, or to increase the flight range of the helicopter can be equipped with additional drop tanks, as well as the possible installation of an additional tank inside the cargo compartment.

For combat operations, the Mi-171 helicopter may be equipped with a system that interferes with all enemy radio frequencies. Night missions include a night vision system and infrared equipment to monitor the situation both on the ground and in the air. For communication, the helicopter has a radar station and a satellite navigation system. The designers thought over the system of emergency excavation, which allows emergency landing of the car on water. All this was achieved with the help of modern equipment of foreign and Russian manufacture.

Due to the fact that the designers were guided by the wishes of the main customer, the helicopter has been installed on the starboard side sliding door, which had a size larger than the standard machine Mi-8. Instead of the usual truck flaps a new car equipped with a ramp on the electro-hydraulic drive.

The car is controlled by two pilots, namely the ship's commander and the co-pilot. The commander's seat is on the left in the cockpit of the pilots. The commander controls the apparatus, makes aiming and launching unguided missiles and fire from guns. The co-pilot is assisting in the management of the machine in situations where the commander makes launch of guided missiles. In addition, the co-pilot performs the duties of navigator, and also manages the system "Sturm", through which the detection of the target and guidance of weapons. Sometimes the co-pilot acts as an arrow from machine guns, which are installed in the bow of the car.

The modifications of the Mi-171

There is quite a large variety of machines of this class, which are designed and constructed for special assignments. The most common machine - a Mi-171SH. This is a military transport helicopter, which is designed to carry 16 paratroopers and military cargo. This machine has weapons that can destroy ground and sea targets, as well as manpower. A more modern modification is considered to be a helicopter, which has a gas turbine power plant and a new navigation system.

To work in the Arctic, and when operating in very difficult weather conditions created by machine Mi-171-BA, flying it is possible even in the polar night. The export model of the Mi-171A1 US has certificates of quality and meets all the requirements of the flight, basically the car is delivered to Brazil. This machine has a significantly better safety profile for use.

The most recent development is the Mil Mi-171A2. At the heart of this machine is the latest development and takes into account all the disadvantages of previous helicopters were involved. For flight tests this machine has started only 2014 year.

And the engine was confused and the maximum take-off weight was underestimated by a whole ton ... And not a word about the fact that the Mi-171 does not fly in Russia. Only abroad. And the latest modification is already the Mi-AMT A3. It will be presented at MAKS.

Article absolutely stupid, never on the basis of certified Mi-171 not created a military helicopter. Version of the Mi-8AMTSH is a military version created on the basis of non-certified Mi-8AMT. A Mi-171SH this export stamp Mi-8AMTSH. So no Mi-171VA Arctic do not exist, there is a Mi-8AMTSH-VA.

Why TV2-117VM instead TV3-117

Typo, certainly, there TV3-117VM
