RUSSIAN HELICOPTERS STARTED CERTIFICATION OF THE MI-171A2 HELICOPTER IN BRAZIL

The Russian Helicopters holding company (part of the Rostec State Corporation) and the Federal Air Transport Agency (Rosaviation) handed over the operational and technical documentation for the Mi-171A2 helicopter to the National Civil Aviation Agency of Brazil (ANAC).
Based on the application received, the Brazilian aviation authorities will have to decide on the certification of the helicopter on the local market.
“Brazil is our long-time partner and one of the key countries in South America for promoting Russian helicopter products. Mi-171A1 helicopters have been successfully operating in the country for more than 10 years, and I am sure that the new helicopter will soon also have the opportunity to earn a positive reputation. Currently, the Brazilian certification authority is processing the received documentation for the Mi-171A2. Taking into account the experience of certification of Mi-171A1 helicopters, I think that this issue will be resolved in short time“, said Andrey Boginsky, General Director of the Russian Helicopters holding company.
“Given Brazil’s high demand for multi-purpose medium-class helicopters, we are introducing a new machine to the local market - modern, spacious and reliable. The Mi-171A2 helicopter provides a long flight range, which is important for a country where helicopters are actively used in hard-to-reach areas. At the same time, within the framework of international partnership, we intend to develop after-sales service, which guarantees maximum operational life and is a necessary condition for flight safety,” said Anatoly Serdyukov, director of the Rostec aviation cluster.
In 2005, the Mi-171A1 helicopter, optimized for the requirements of European commercial operators and FAR-29 aviation regulations, received Type Certificate approval from ANAC. During its development, special attention was paid to safety issues. In the same year, the first Mi-171A1 helicopter was delivered to Brazil.
In 2010, the Mi-171A1 helicopter, presented by the operating company Atlas Taxi Aereo, based on its positive characteristics and price/quality ratio, won the tender of the Brazilian state oil and gas company Petrobras for the right to perform aerial work in the Amazon River basin.
By order of a Brazilian company, the T-HUMS system (on-board monitoring and diagnostic system) was installed for the first time on the new Mi-171A1 helicopter. It provides automatic monitoring of a wide range of components in real time, significantly increasing flight safety. The use of the T-HUMS system also provides for the possibility of switching to maintenance “on condition” rather than according to regulations, which can significantly reduce the financial costs of the operator company and increase the efficiency of the helicopter business.
Mi-171A1 helicopters used by Atlas Taxi Aereo in heavy duty natural conditions to support Petrobras' drilling operations in the rainforests of Brazil, have proven themselves to be best side. During a year of intensive operation, one helicopter, for example, flew more than 1 thousand hours (an average of 120 hours per month), moving about 600 tons of cargo, mainly drilling equipment on an external sling.
On the basis of this helicopter, the Mi-171A2 helicopter was developed - the result of a deep modernization of helicopters of the Mi-8/17 family. More than 80 changes were made to the Mi-171A2 design. The helicopter is equipped with VK-2500PS-03 engines (civil version of engines installed on Mi-28 combat helicopters) with digital system management. One of the most important differences between the Mi-171A2 and the Mi-8/17 family of helicopters is the new load-bearing system. The helicopter is equipped with a more efficient X-shaped tail rotor and a new main rotor with all-composite blades with an improved aerodynamic design. In August 2017, the helicopter received from Federal agency Air transport of the Russian Federation type certificate for category “A”, which provides for compliance with the most stringent flight safety requirements for civil helicopters.
JSC "Ulan-Ude aircraft factory" - one of manufacturing enterprises holding "Russian Helicopters". The modern production and technological potential of the plant allows us to quickly organize the production of new types of aircraft and combine the creation of prototypes with serial production of equipment. Over the 75 years of its existence, the plant has built more than 8,000 aircraft. Today the plant specializes in the production of Mi-8AMT (Mi-171E), Mi-171 and Mi-8AMTSh (Mi-171Sh) helicopters.

The Russian Helicopters holding company predicts great demand for helicopters in the world - in the next 5-10 years, demand will increase by 20%, aereo.jor.br reports on March 16. In Brazil, sales will increase by 37%.
The company begins certification of the Mi-171A2 multi-purpose transport helicopter in Brazil. Since 2000, Russia has sold 16 helicopters of various types to Brazil.
“Brazil is our long-time partner and one of largest countries South America. Mi-171A1 helicopters have been successfully operating in the country for more than 10 years, and I am sure that the new helicopter will also be positively received,” adds Andrey Boginsky, General Director of the Russian Helicopters holding company.
The previous version of the Mi-171A1 was created in 2005, optimized for the requirements of mainly European consumers, and received the Brazilian FAR-29 certificate. In the same year, the first helicopter was delivered to Brazil.
The Mi-171A2 variant received more than 80 changes compared to the A1, and is equipped with VK-2500PS-03 engines with a digital control system (a civilian version of the engine installed on the Mi-28 combat helicopter). Production is carried out at the Ulan-Ude aircraft plant (part of the Russian Helicopters holding company). Over more than 75 years of operation, the plant has built more than 8,000 aircraft and helicopters. Today the plant specializes in the production of Mi-8AMT (Mi-171E), Mi-171 and Mi-8AMTSh (Mi-171Sh) helicopters.
Military parity

“With the advent of European helicopters, disaster medicine in the region has reached a qualitatively new level.

To carry out air ambulance work in the Primorsky Territory, two light AS350 B3e (H125) helicopters manufactured by Airbus Helicopters are used. These vehicles were purchased by the regional administration in 2015 as part of the state program “Development of the transport complex of the Primorsky Territory for 2013–2020.”

Needless to say: would the residents of the Primorsky Territory “disappear” without the H125?

Meanwhile, India is purchasing 200 coaxial Ka-226s from us, which won international competitions over the same H125s.

Among the Kamovites in the 90s. There was also a more modern project with one engine: the coaxial Ka-115, but safer than the H125, cheaper, more advanced and more spacious, where instead of one accompanying person a doctor and a nurse could be accommodated, i.e. brigade

But for a liberal government official, a helicopter with a tail rotor is a balm for the soul! Probably because of its drift: with the rotors running, the tail rotor is very dangerous on the ground; if there is a failure in the air, with rare exceptions, it is a disaster; takes away part of the engine power to the detriment of the payload; and for the solidity of the fuselage, a heavy tail boom with gearboxes is attached to it. A coaxial helicopter also has a tail boom, but it is “fluffy” in comparison with the tail boom of the classical design. While a coaxial helicopter can easily fly tail first at any speed, the Kalashnikov Mi-8 is not allowed to fly backwards even when maneuvering before landing:

“The cause of the accident was the aircraft entering the “vortex ring” mode when performing a helicopter landing without using the influence of the “air cushion”. The crew did not attempt to exit this mode using the method specified in the Flight Operating Manual of the Mi-8T helicopter undertook," the IAC said in a statement.

According to the IAC, this happened because the crew made a mistake; the helicopter was flying “tail first” at speeds of up to 40 kilometers per hour. There is no such maneuver in the helicopter operating manual" (The IAC Commission completed an investigation into the aviation..."Airport").

Now let's compare the performance characteristics of the Mi-8 MTV and Ka-32 with the same TV3-117 engines

The small number of passengers on the Ka-32 is explained by its small fuselage volume. The fact is that this helicopter is a modification of the Ka-27, built in Soviet times specifically for the Navy. But the Kamovites have been using the Ka-32 since 2001. there is a Ka-32-10 project with a fuselage volume commensurate with the Mi-8, but the main gearbox and main rotors- serial from the Ka-32, so at the end of the day it is supposed to be no more expensive and even cheaper than today’s Mi-8, which, in my opinion, does not suit “effective” managers, because you can’t make a lot of money from a Kamov helicopter and, Presumably, because of this, its implementation was “FROZEN”. And in general: it is not permissible for Russian engineers to launch a better helicopter than the WESTERN one into production! Therefore, instead of the Ka-32-10AG project, Russian Helicopters launched the Mi-171A2 series with the same VK-2500 engines, but which also loses in all respects: in safety, in payload capacity; in terms of speed characteristics, the Ka-32-10AG will not be inferior to the Mi-38, and on an external sling it will lift a ton more, which indicates the large power capacity of the Ka-32-10AG. But the Mi-171A2 is being prepared for Arctic flights:

“July 18th. As part of the recently announced project to develop an offshore version of the Mi-171A2 helicopter, the machine will be adapted to work in Arctic conditions, Russian Helicopters told ATO Show Observer. This will be required due to the fact that the machine is planned to be used, among other things, on the Arctic shelf.

The holding hopes that the experience of developing “Arctic” helicopters will allow the offshore version of the Mi-171A2 to be brought to market relatively quickly. The machine is being developed in the interests of fuel and energy companies.”

Of course, it would be much more economically profitable for the State to have a coaxial helicopter, when the basic Ka-32 has long been tested in real Arctic conditions, than to “fence the garden” with the Mi-171A2:

“In the Arctic, a trial unloading of a supply vessel onto an unequipped shore was carried out using a Ka-32 helicopter. An experienced polar explorer, Hero of the Soviet Union, Mark Ivanovich Shevelev, took part in this experiment.”

Mark Shevelev recalls:

“We had to supply the polar station on Bear Island with everything necessary for a long winter. Typically, such an operation in the Arctic takes a long time. There are no piers, snow, wind, and on a pontoon you can’t always get right to the shore. In short, people drag loads in icy water, and even special suits cannot save them. It is especially difficult to carry fuel containers by hand. But everything needs to be moved as far as possible from the sea, beyond the line of maximum tide. And so, despite the fog, with the help of the Ka-32 helicopter we completed unloading the Sasha Borodulin vessel in just a day and a half.

The helicopter picked up a container with a five-ton cargo from the deck and carried it to the island to the very house of the meteorological station.”

Why couldn’t it have been possible to invite a rotorcraft to become riggers and loaders before? The fact is that in polar conditions only the Ka-32 can be reliably used to operate from ships. The helicopter successfully passed comprehensive tests. Sailors, scientists, and pilots appreciated its enormous capabilities.

The commander of the civil aviation helicopter pilot unit, Valentin Andreev, says:

“Ka-32 even us who flew helicopters different designs, surprised. This compact, tough guy has great engines. It has on board an excellent flight and navigation system and a computer, with the help of which you can fly automatically over the ocean both during the day and in the polar night without a drive station and dispatchers. Electronic equipment always keeps the right course.”

This car is a godsend for the Arctic. Ka-32 helicopters as part of Arctic convoys will bring serious savings national economy"(Holiday on Medvezhy Island. The right course. World records of the Ka-32.).

The launch model of the domestic Mi-171 helicopter is a modification of the eighth series, put into service in 2009. The flying machine has several modifications and is considered a multifunctional device capable of performing not only combat missions, but also functioning as a rescue or passenger ship. Let's consider the features of this modification, as well as its characteristics.

Layout and creation

The Mi-171 helicopter is produced by an aviation plant located in Ulan-Ude. The modification was released on the basis of a universal model under the index 17. The aircraft has modern tactical and technical characteristics in its class, as well as increased autonomy and safety.

The designers took into account not only modern trends in aircraft construction, but also took all the best from previous developments. This solution made it possible to obtain a technically optimized machine with electronic filling and excellent ergonomic properties. The idea was fully realized through close cooperation between engineers and equipment operators, as well as the introduction of electronic and digital components.

Innovations

Mi-171 is a helicopter that was designed on the basis of the Mi-17 and Mi-8 lines. At the same time, the car received many additions. The supporting platform has undergone significant modernization. The device was supplemented by an X-shaped tail rotor, as well as a stabilizing system against distortion. Additional benefit is the introduction of modern composite materials.

Improvements to the design plan had a positive impact on operational parameters. The controllability and traction power of the propeller have increased. The flight range of the new model has increased to 800 kilometers in autonomous mode. For comparison: the previous basic version could cover only 650 km without additional support.

Technical plan parameters

The Mi-171 belongs to the middle class rotary-wing aircraft. It is designed for multi-purpose use, combining practicality, good ergonomics and functionality. Below are the main technical characteristics of this helicopter:

  • Maximum curb weight is 13 tons.
  • Weight with load on external sling - 13.5 tons.
  • The cargo compartment capacity is 4 tons.
  • Suspension load capacity - 5 tons.
  • The length of the cabin is 6.3 meters.
  • The cabin width is 2340 millimeters.
  • Machine height - 1800 mm.
  • The useful volume of the cabin is 23 cubic meters.
  • Passenger capacity - up to 26 people.
  • Crew composition: 1-3 pilots.
  • The range of climatic conditions in temperature is from -50 to +50 °C.
  • Cruising speed is 230 kilometers per hour.
  • Flight range - 650-800 kilometers in autonomous mode.

In addition, the aviation equipment of the Mi-171 helicopter includes a twin GTD TVZ-117 (VK-2500) engine, which has a power of about 2 thousand horsepower. At the same time, the working ceiling of the device is 5 kilometers in height.

More about the power unit

The engine of the modification in question is a motor with a gas turbine belonging to the VK-2500 PS series. Power point equipped with an electronic unit for adjusting current parameters. The launch of the Mi-171 unit at an altitude of up to 6 kilometers is guaranteed by a special Safir APU system. The take-off potential of the improved version of the aircraft is 2,400 horsepower, and the maximum speed can reach 280 kilometers per hour.

Peculiarities

Among the design features of the multi-purpose domestic Mi-171 helicopter, the diagram of which is given below, one can note an improved load-bearing platform and an updated transmission. As a result, the device has become more reliable and practical.

In addition, the machine has become easier to maintain and operate. A significant role in this aspect was played by the installation of a flight navigation system, which improved the comfort and avionics of the helicopter. An additional benefit is the reduction in flight cost per investment per hour spent. It is also worth noting the increased cabin comfort and improved technical parameters.

Mi-171: technical operation manual

An aircraft of this class is designed to perform a variety of tasks. The helicopter can be used when high rates air temperature, as well as in high mountainous areas. In addition, the updated rotary-wing unit can be operated in almost any meteorological situation.

Stable navigation combined with the latest radio-electronic equipment allows flights not only over land, but also over water. Excellent visibility is provided by the panoramic glazing of the cabin and the proper placement of additional equipment. The machine can be controlled by one or a pair of pilots, whose control unit is combined.

Modifications

Below are models of the Mi-171 helicopter.

  1. 8-AMTSH - military vehicle. The device is designed to transport a landing force of 16 people. In addition, the vehicle can carry up to 12 wounded soldiers on stretchers, as well as 2-3 medical personnel. The vehicle's carrying capacity is 4000 kg in the cargo compartment and the same on the external sling. Main purpose: search, military, rescue operations and fire fighting.
  2. Mi-8 AMTSH-V - a model created for military transport operation, has an improved auxiliary installation and updated avionics.
  3. 8 AMTSH-VA. This modification is aimed at working in the regions of the Far North and other areas with harsh climates.
  4. Mi-171A1. This specimen is a modernized version of the 8AMT series. It has a fuel system without a supply tank, as well as fire-resistant steel hoods and special boosters with two chambers that have increased fire protection.
  5. Variation 171 A2 has a more modern power unit, better tactical and technical characteristics, reduced maintenance costs, and a longer flight range without refueling.

Prospects

The Mi-171 aircraft in question, books on the arrangement of which are filled with comprehensive information about technical data, was tested for a long time in special flight laboratories. Some samples are released in a standard version. Other models received new main and additional propeller blades, as well as other elements.

The designers have several projects in their plans that are aimed at application in the transport, military, search, medical and passenger fields. Taking into account the characteristics of the machines being developed, they receive appropriate equipment. The core base will likely remain the same. The main emphasis will be on optional equipment and expanding the configuration, taking into account the purpose of a particular model.

The capabilities of the updated modification make it possible to expand the areas of its use not only in industrial terms, but also as a business model. The parameters and characteristics of a rotary-wing aircraft make it possible to transport petroleum products to remote regions. The plant in Ulan-Ude not only supplies to the domestic market, but also considers the prospects for developing export-import relations with the CIS countries and foreign countries.

As for accidents with this helicopter, they took place. Among the most resonant events are the following cases:

  1. December 19, 2009 - accident near Vorkuta. The ship made an emergency landing in the tundra. The airship belonged to the aviation company Gazpromavia. There were 25 people on board, including crew members. One passenger subsequently died from injuries incompatible with life, the other was seriously injured.
  2. Soon after this, a Mi-171 helicopter of the Azerbaijani military forces fell into the sea near the city of Baku. Three crew members were killed.
  3. In July 2014, a disaster occurred in Vietnam (Hanoi). There were 21 paratroopers on board the ship. The accident killed 16 people.
  4. In the Chinese province of Sichuan, five people were injured after the accident of the Mi-171 helicopter, which crashed on July 22, 2014.
  5. An aircraft of the brand in question, which was transporting a sick child, crashed near the Belgrade airport (Serbia). Also on board were paramedics and crew members. Presumably, the cause of the disaster was bad weather conditions. This happened in March 2015.
  6. On October 19, 2016, another accident occurred. The MI-171 military helicopter, the design of which is quite reliable, but imperfect, crashed in the Fergana region. Nine people (crew members and paratroopers) were killed. The accident occurred due to unfavorable weather conditions.

In conclusion

Aviation equipment Mi-171 has good characteristics. There are many modifications of helicopters that are designed for operation in different fields of activity. The design of the machines is constantly being improved and supplemented, which allows us to hope for even greater safety during flights and active use of the device in all regions of the country and neighboring countries.

New concept

From January 21 to 23, the 4th International Aviation Exhibition was held in Bahrain, in which 139 companies from 35 countries, including Russia, took part. The Bahrain Air Show, despite its youth, is one of the top ten events of this kind in terms of representativeness.

And it all started in 2010 (the salon is held every two years) with a very modest exposition, which was presented by a little over three dozen companies from 15 countries. In connection with this, wits claimed that the king of Bahrain became bored and decided to admire the beautiful airplanes. However, even then it was clear that the Bahrain salon would become a noticeable phenomenon in the aviation business in the foreseeable future. If only because to the creation of the concept and to organizational activities To promote the salon, specialists from the world-famous British aerospace exhibition in Farnborough were involved.

The Bahrain Air Show has significant novelty. There are no traditional pavilions for this type of event, where the general public gets acquainted with the latest achievements of aircraft manufacturers. Finished products - airplanes, helicopters and others - are available to the general public. aircrafts located at the airport. As well as performances by aerobatic teams from around the world. This salon is a business-to-business model - B2B. That is, maximum opportunities are provided for business contacts between aircraft manufacturers and the companies purchasing their products and services (air carriers and military structures). “Firmachi” are located in 40 chalets, where they receive delegations of equipment purchasers and conduct negotiations.

The air show was held at the Sakhir airbase in close proximity to the F1 auto racing track. It was opened personally by the King of Bahrain Hamad bin Isa al-Khalifa. The event was attended by 33 military organizations from 19 countries and 59 civilian organizations from 24 countries. 108 aircraft were presented.

During the three days of the salon’s work, deals were concluded for total amount exceeding 9 billion dollars. Of course, this is only a preliminary result. In the future, after a more detailed acquaintance with the equipment, the conditions of its delivery and service, after approval of transactions at the highest level corporate level, new contracts will follow.

First things first - helicopters

Russia in Bahrain was represented by the companies of Sukhoi and Ilyushin, as well as the United Helicopter Corporation and Rosoboronexport. The interest of customers from the air forces of a number of countries in Russian aircraft was naturally fueled by the successful actions of our aviation in Syria. Well, the King of Bahrain made an excellent advertisement for helicopters, saying that they “surprised” him. Which was immediately reflected in a number of foreign media, including even one Ukrainian informational portal.

Helicopter manufacturers exhibited their latest multi-role helicopters- Ka-32A11BC, Mi-171A2, Ka-226T and Ansat.

The Ka-32A11BC is a modification of the Ka-32 helicopter intended for export. The abbreviation BC means that it was certified in Canada (British Columbia). Subsequently, certification expanded to Europe, Australia, Brazil, China, South Korea and Japan. Now the Kamov apparatus must penetrate into the Middle East. It is planned to expand the production of this machine by opening an assembly plant in China.

The Ka-32A11BC is a medium helicopter with Kamov’s signature coaxial propeller system. Capable of transporting 3,700 kg in the cargo compartment, and 5,000 kg on an external sling. Has a range of 800 km, service ceiling - 5000 m, maximum speed— 260 km/h. Compared to other modifications, the Ka-32 has an increased service life.

The Ka-226T is a light helicopter capable of carrying 6 passengers over a distance of 600 km. IN equally It is used both on civilian lines and as part of the Air Force. It has enormous export potential. Late last year, India signed a contract to purchase 200 of these vehicles for its armed forces. The order may be increased to 400 helicopters.

Developed by the Kazan Helicopter Plant, Ansat is also a lightweight machine. And it is also operated by both civilians and the military. The cabin can accommodate up to 9 passengers or one and a half tons of cargo. There is a modification with increased comfort, which allows for the transportation of VIPs.

The greatest interest in Bahrain was caused by the Mil OKB Mi-171A2. This is completely new car, testing of which began in 2014. It is a continuation and deep modernization of the famous family of Mi-8/Mi-17 helicopters. It has improved flight performance and operational characteristics. It differs from the “eight” in increased load capacity, reinforced fuselage and beam. The Mi-171A2 has a more advanced tail rotor. All avionics are modern, latest generation. Due to the use of more powerful engines, it is capable of flying in any weather, including strong crosswinds. At the same time, the cost of operating this machine is reduced compared to previous modifications.

Rosoboronexport produces foreign currency

The Sukhoi Design Bureau presented its superjet SSJ100 in Bahrain - a short-haul passenger aircraft that carries 100 passengers and has a range, depending on the modification, from 3000 km to 4500 km. This is not a new product; the aircraft has been in operation for the fifth year. During this time, the number of operators exceeded ten. Bahrain has ordered 5 Sukhoi airliners. The Irish airline SityJet placed an even larger order last year - 21 aircraft. As a representative of the Sukhoi Civil Aircraft company stated at the show, production capacity loaded three years in advance. This year, 31 aircraft will be delivered to customers.

The main “product” of the Ilyushin Design Bureau is the Il-96MD transport aircraft, which is equally effectively used in both military and civil aviation.

Well, and finally, the most important foreign exchange earner is Rosoboronexport. Unfortunately, the “Russian Knights” aerobatic team on multirole highly maneuverable fighters Su-27P and Su-27UB did not make it to the salon. This happened because Iran was late in granting permission for military vehicles to fly over its territory.

The Rosoboronexport delegation held negotiations for three days with representatives of the armed forces of the countries of the Middle East and North Africa expressing interest in the purchase Russian aircraft, helicopters and aircraft weapons.

The negotiating partners showed great interest in the 4++ generation fighters Su-35 and MiG-29M/M2, the Yak-130 combat trainer aircraft, the Il-76MD-90A military transport aircraft, the Ka-52 and Mi-28NE attack helicopters, Mi-35M transport and combat helicopter.

“Rosoboronexport’s order portfolio for aviation equipment exceeds $22 billion,” said the head of the delegation Head of the Department of Export of Special Equipment and Services of the Air Force Sergei Kornev. — Interest from foreign customers is growing, including in the countries of the Middle East and North Africa. This is due both to the launch of new models on the international market and to the high effectiveness of the use of modern Russian military aircraft, including its ability to carry out targeted strikes on ground targets. The strengthening of demand is facilitated by the excellent efficiency-cost ratio, as well as Russia’s reputation as a reliable and responsible partner in military-technical cooperation.”

No contracts have been announced. They should appear in the foreseeable future.
