The minimum flight altitude is mi 8. The maximum speed of the helicopter. The fastest helicopters. Combat use in Afghanistan

The history of the MI-8 helicopter began in the USSR. For the first time, it was developed in the early 60s. It is he who is the most massive twin-engine helicopter, not only in Russia, but throughout the world. The main purpose of using this aircraft is various military and civil operations.

After all, it is thanks to its technical and flight characteristics that this aircraft has earned its authority among many air forces in the world. Due to the rich range of possibilities for 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 foreign countries are also actively purchasing this helicopter for service.

Thanks to good speed and technical specifications Today, its design modifications are very actively carried out. Together with a good flight range, the MI-8 model is one of the highest priority aircraft for its further improvements. Thus, MI-8 definitely takes pride of place in our aviation industry.

Modifications of the MI-8 helicopter

Over the years of history, after the release of the first prototype, many different modifications of this aircraft 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 of both the MI-8 itself and its modifications. In other words, these are different models of this helicopter, in which certain changes were made.
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 is able to accommodate 18-30 people, depending on the modification, which makes it very attractive for this purpose.
Transport. MI-8 is capable of carrying cargo with a total weight of up to 4 tons. Not many helicopters can boast of such characteristics. And because of the possibility of using it to perform multi-purpose tasks, it remains completely out of competition.
Multipurpose. In addition to all the above uses, the MI-8 is capable of another range of different combat missions. good example this can be 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 in search and rescue operations. Sometimes, it is also used as an air hospital, again, using special equipment.

Separately, it is worth noting one of the newest modifications 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 with the aim of conducting combat operations in a wide variety of climatic conditions. Unlike older models, here they introduced the possibility of transporting bulky cargo by attaching it to the external suspension of the helicopter. And thanks to its combat and speed characteristics, new version helicopter, it became possible to conduct fire support for the allied infantry. Moreover, thanks to the latest equipment, it is not at all necessary to conduct fire support in daytime conditions.

And if this model shows itself well in combat conditions, then it will definitely be accepted for permanent service. And to have such a reliable and efficient technique 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 main rotors and three tail rotors. The propeller blades, made of solid metal, have a full spar made of aluminum alloys pressed together. In addition, all helicopter blades have an alarm, and in case of damage to any of the blades, the pilots will be immediately notified of this.

Due to the presence of two engines, in the event of a failure of one of which, the second automatically increases the supplied power by using modern equipment. That allows not to lose speed and maneuverability in case of malfunctions. And this is an undeniable advantage among other helicopters of a similar model.

In some modifications of the MI-8 helicopter, a specialized armored cabin is used. Often, such modifications are used in combat models. And such variations are very often adopted 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, one of the best antifreeze systems is installed on the helicopter. It is she who does not allow the helicopter to freeze. Thanks to this, it can be used even in the most extreme conditions.
The MI-8 helicopter has 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. Besides, this system also works on the front windows of the helicopter and air intakes.

The MI-8 helicopter has a rather serious electronic filling. And she, in turn, has absolutely various characteristics and purpose. But it is precisely due to it that the helicopter has its own special distinctive properties.

It should be noted that the flight characteristics of the helicopter itself are very attractive. good speed, along with its cargo-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 developing to this day.

In addition, when installing necessary equipment helicopter can be used in various modifications to solve special problems. The tasks to be solved and recommendations for the flight operation of these modifications are set out in the relevant sections of the Instructions to the Crew.
For the transportation of bulky goods in the cargo compartment (such as rotor blades) and perform training jumps with parachutes(parachute landing) through the cargo hatch on the helicopter, a semi-open position or removal of the doors of the cargo compartment is provided.

Military transport version of Mi-8/17 type helicopters on this moment continues to be one of the most used helicopters in its class. These helicopters were created taking into account comprehensive analysis rich experience in the use of domestic helicopters in combat operations in various hot spots on the planet. High performance characteristics and versatility have made this helicopter one of the most popular helicopters in the world Russian production. The Mi-8AMTSh and Mi-8AMTSh-V helicopters are now entering service with the Russian army, and a special version of the helicopter has also been developed for operation in the Arctic. Currently, helicopters of these types are produced at the facilities of the Ulan-Ude Aviation Plant.

Mi-8AMTSH helicopters (export designation Mi-171Sh) are designed to transport personnel, as well as various cargoes inside the cabin and on an external sling. They can be used, among other things, for rescue operations, as well as carry various weapons. The helicopter was developed on the basis of the Mi-8AMT multipurpose helicopter at the Ulan-Uda Aviation Plant. The unofficial nickname of this machine is "Terminator", under this designation the helicopter was demonstrated in 1999 in the UK at the Farnborough Air Show. The helicopter was adopted by the Russian Air Force in 2009.

This helicopter has retained good landing and landing capabilities. The experience of modern local conflicts and wars shows that a helicopter has very little time, only a few tens of seconds for landing, says Major Alexander Barsukov, pilot first class. After that, the car can be easily knocked down, even despite very good armor. In order to reduce the landing time, the Mi-8AMTSh helicopters received sliding doors that open from two sides, as well as an automatic ramp, which replaced the mechanical doors. The main difference between the car was the ability to make night flights. Flying with night vision goggles is a fairly new thing for Russian helicopter pilots. It is their use that makes it possible to ensure the night use of the Mi-8AMTSh helicopter.

If necessary, a guided weapon system can be installed on the helicopter, which will be similar to the Mi-24 helicopter. In addition, the helicopter received enhanced armor protection (lightweight ceramic-metal armor), as well as new avionics. New complex Helicopter avionics includes but is not limited to weather radar, pilot night vision goggles, satellite navigation equipment and infrared equipment. The defense complex of the Mi-8AMTSh helicopter includes the ASO-2V trap shooting system and screen-exhaust devices.

The armament of the helicopter can be placed on 4-6 beam holders located on the sides of the fuselage. According to the official website of the Russian Helicopters holding company, the vehicle’s onboard armament range includes up to 4 B8V20-A blocks with 80 mm S-8 unguided rockets, as well as up to two cannon containers with 23 mm GSh-23L rapid-fire cannons, as well as two 7.62 mm PKT machine guns in the bow and stern mounts. In the troop compartment of the helicopter there are 6 pivot installations for attaching infantry paratroopers.

The Mi-8AMTSH helicopter is distinguished by the presence of an additional armor that protects the crew members. Armor covered the bottom and front of the cockpit. There is an armor plate between the cockpit and the cargo compartment, and the armor plate is also installed in the cargo compartment under the shooter's position. The helicopter crew consists of 3 people: crew commander, pilot-navigator and on-board technician. During the evacuation of victims and carrying out various rescue operations, a medical worker (s), rescuer (s) may be present on board the helicopter.

The Mi-8AMTSh-V military transport helicopter with two VK-2500 turboshaft engines is designed to increase the mobility of ground forces, as well as provide them with fire support on the battlefield. By helicopter, you can perform the tasks assigned to it day and night, in simple and difficult weather conditions. With this helicopter, you can perform the following main tasks:

Landing of tactical and operational-tactical airborne assault forces;
- ensuring the maneuver and actions of troops during the battle;
- destruction at the forefront and in the tactical depth of infantry fighting vehicles, artillery and tactical missiles at firing (starting) positions, anti-aircraft weapons, anti-tank weapons, enemy manpower in combat and pre-combat formations, including strong points, radar posts, forward control points, transport and combat helicopters in parking areas;
- destruction of airmobile units and subunits, air (sea) landing in the landing (drop) areas;
- aerial reconnaissance of enemy positions;
- ensuring the passage of tactical and operational-tactical airborne assault forces to the landing area and air support for paratroopers;
- search and rescue of crews of helicopters and aircraft in distress;
- evacuation of the sick and wounded.

To solve all the above tasks, the Mi-8AMTSh helicopter can be used in amphibious, transport, combat or ambulance versions:

1) landing version - designed to transport paratroopers with equipment (maximum 20 people, with additional landing seats installed - 34 people).

2) transport option: a) without installing additional fuel tanks (for transportation of goods weighing up to 4000 kg in the cargo compartment); b) with one additional fuel tank; c) with two additional fuel tanks; d) for the transportation of goods weighing up to 4000 kg on an external sling; e) for the transportation of bulky goods located inside the cargo compartment with an open ramp.

3) combat version with installed weapons: a) with blocks B8V-20A; b) with small arms and cannon weapons, containers UPK-23-250 are used; c) with bomber weapons.

4) sanitary option: a) with the wounded on a stretcher (maximum 12 people); b) combined option - seated wounded and wounded on stretchers (maximum 20 people: 17 seated and three on stretchers); c) with one additional fuel tank and wounded (maximum 15 sitting wounded).

5) distillation version: with two additional fuel tanks, which are installed in the cargo compartment.

To fulfill the tasks of the Ministry of Defense of the Russian Federation in the Arctic, the Russian Helicopters holding company created a specialized Mi-8AMTSh-VA helicopter, which was created on the basis of the latest modification of the Mi-8AMTSh-V military transport helicopter, which was distinguished by the installation of new gas turbine engines "Klimov" VK- 2500-03, as well as a more powerful auxiliary power unit (APU) TA-14 and an updated set of avionics.

The Mi-8AMTSh-V helicopter is being created taking into account the policy of import substitution announced in Russia. This helicopter is the latest modification of the famous Mi-8 and has already received high marks from military pilots. “Today we understand the importance of our maximum independence from foreign components and assemblies for equipment that is supplied to the Russian armed forces as part of the state defense order, and we are purposefully working in this direction,” Alexander Mikheev, CEO of the Russian Helicopters holding, told reporters. Moreover, using the Mi-8AMTSh-V as an example, we see that the use of Russian equipment in some cases makes it possible to achieve significant improvements in helicopter performance, Mikheev noted.

In order to reduce dependence on foreign suppliers, all Mi-8AMTSh-V helicopters were equipped with modern equipment domestic production. More than powerful engines VK-2500-03, which are produced by the Klimov company (part of the United Engine Corporation). The VK-2500-03 engines are a further development of the TVZ-117 family of engines and have improved characteristics, which can significantly increase the reliability and safety of the combat use of the helicopter and the overall performance of the vehicle. In addition, the increased resource of domestic engines should have a favorable effect on the cost of operating the Mi-8AMTSh-V in the army.

Another area of modernization of the helicopter was the replacement of the AI-9V power plant, which was produced in Ukraine, with the domestic model TA-14, which is produced by NPP Aerosila. Auxiliary power unit TA-14 is characterized by greater power, as well as increased operating time in generator mode. TA-14 has the best launch altitude performance (6000 meters versus 4000 meters for its predecessor). Thanks to the installation of a new auxiliary installation, the capabilities of the rotorcraft during its operation in high-mountainous terrain and autonomous basing have increased significantly.

The satellite navigation system BMS of domestic production installed on the Mi-8AMTSh-V can work both with GPS and with Russian system GLONASS. Modern complex communications equipment also of domestic production allows the crew of a combat vehicle to use high-quality communications in a wide frequency range. For flight safety and the convenience of the crew, a new domestic weather radar was installed on the machine, which has the function of outputting a three-dimensional image of meteorological formations and objects. Information from navigation equipment and weather radar, which improves piloting comfort and flight safety, is displayed on a multifunctional large digital display in the cockpit.

To increase the combat survivability of the vehicle and crew, the helicopter is equipped with modern Russian ceramic-metal armor, which, compared to steel armor more durability with less weight. Protection and armament systems, modern Russian radio communication and flight navigation equipment, as well as a wide range of additional equipment allow the Mi-8AMTSh-V military transport helicopter to meet all modern requirements.

Mi-8AMTSh helicopter flight manual

Mi-8 (multipurpose transport helicopter)

Description of the helicopter

The first version of the Mi-8 helicopter with a four-blade main rotor was tested in 1962. In October 1963, the second variant with a five-blade main rotor began to be tested, which at the end of 1965 was adopted in mass production. The Mi-8 exceeds the Mi-4 helicopter in maximum payload capacity by 2.5 times and in speed by 1.4 times. The transmission of the Mi-8 helicopter is similar to that of the Mi-4 helicopter. All-metal rotor blades. They consist of a hollow spar pressed from aluminum alloy. All main rotor blades are equipped with pneumatic spar damage alarm. Powerful hydraulic boosters are used in the control system.

The Mi-8 is equipped with an anti-icing system that operates in both automatic and manual modes. The external suspension system of the helicopter allows you to carry loads weighing up to 3000 kg. If one of the engines fails in flight, the other engine automatically switches to increased power, while level flight is performed without lowering the altitude. The Mi-8 is equipped with an autopilot that provides roll, pitch and yaw stabilization, as well as a constant flight altitude. The navigation and flight instruments and radio equipment that the helicopter is equipped with make it possible to fly at any time of the day and in adverse weather conditions.

The helicopter is mainly used in transport (Mi-8T) and passenger versions. In the passenger version, the Mi-8P is equipped to carry 28 passengers. By special order, in Kazan, a variant with a deluxe cabin, designed for seven passengers, can be made. Orders were completed for B. Yeltsin, N. Nazarbayev, M. Gorbachev and others. The military version of the Mi-8T has pylons for hanging weapons (NUR, bombs). The next military modification of the Mi-8TV has reinforced pylons for hanging a large number of weapons, as well as a machine gun mount in the bow of the cabin. By rearranging the RV to the left side, its effectiveness was increased.

The Mi-8MT is the latest modification of the helicopter, which was the logical conclusion of the transition from a transport to a transport-combat helicopter. More modern TVZ-117 MT engines were installed with an additional AI-9V gas turbine unit and a dust protection device at the air intake inlet. To combat surface-to-air missiles, there are systems for dispersing hot engine gases, shooting false thermal targets and generating pulsed IR signals. In 1979-1988. Mi-8MT helicopter took part in the military conflict in Afghanistan.

The equipment includes - VHF command radio stations R-860 and R-828, HF communication radio stations R-842 and Karat, aircraft intercom SPU-7. Four-channel autopilot AP-34B for automatic stabilization of the helicopter in pitch, roll, heading and flight altitude. Equipment for instrument flight in SMU day and night, including two AGB-ZK artificial horizons, two NV speed indicators, a GMK-1A combined heading system, an ARK-9 or ARK-U2 automatic radio compass, and a RV-3 radio altimeter. The Mi-8T is equipped with RI-65 voice communication equipment to notify the crew of emergencies in flight. On the military versions of the Mi-8MT, the Lipa IR interference station, screen exhaust devices for suppressing the IR radiation of engines, containers with LCs, and an armored cockpit are installed. At the request of the customer, an external cargo suspension system and a winch with a lifting capacity of 150 kg are installed.
