Aircraft l 410 technical specifications. How it's done, how it works, how it works. Specifications L410 UVP-E20

The Russian Urals Mining and Metallurgical Company (UMMC) has decided to become the sole owner of the production of a small local airliner (IL) aircraft Let L-410, also known as the Turbolet. To this end, UMMC is going to increase its own stake in the block of shares of the Czech company Aircraft Industries from 51% to 100%, ITAR-TASS reports. The L-410 aircraft is considered by the Russian side as the main model for modernizing regional aviation fleets and restoring the network of local airlines. It is expected that the leasing of new aircraft will be supported by the budget. The heads of Russian regions are going to determine specific mechanisms for this support at a meeting in September 2013.

Currently, the main product of the Czech airline is the L-410UVP aircraft. This model is a short-haul aircraft with a short takeoff and landing distance for 19 passengers. The first modification of the aircraft Let L-410 took to the skies in 1969. In the post-war years, the Czech "Turbolet" became the first foreign aircraft that entered the Soviet airlines. On the basis of this machine, a large number of different modifications of transport, military and special purposes were created. In particular, this aircraft is widely used in Russian military and civilian flight schools, where it serves to train future pilots of military transport and long-range aviation.

After the transfer of 51% of the shares of the Czech company to UMMC, the Czech aircraft manufacturer received additional orders for its main product - L-410 UVP-E20. In 2009, after a rather long break, deliveries of aircraft to Russian customers resumed - first to civilian companies, and later to the RF Ministry of Defense. As of 2012, the Russian Air Force was armed with 7 L-410 UVP-E20 aircraft, while the contracts and options concluded involve bringing the fleet of these aircraft to 15 aircraft.

Today, Aircraft Industries supplies the Russian regions with an upgraded version of the aircraft, which is equipped with H-80 turboprop engines, which are produced by the General Electric division in the Czech Republic. According to the UMMC, the installation of these engines significantly improved the performance of the aircraft, increasing, in particular, the flight range from 1420 to 1520 kilometers. Currently, the L-410 aircraft is listed in the parks of the Russian companies KrasAero and Orenburg. The Buryat airline PANH and the government of the Khabarovsk Territory are ready to purchase several aircraft. Earlier, the Ministry of Transport and the Ministry of Industry and Trade of Russia stated that 9- and 19-seat aircraft were needed for the development of the domestic air transportation market, but such modifications were not made in Russia.

Let L-410 "Turbolet" - Czechoslovakian, later Czech, twin-engine universal aircraft designed for operation on local airlines (IL). It is a twin-engine turboprop high-wing aircraft with a single tail. Also known under the names: Let, Let L-410, L-410, Turbolet, Elka, Cheburashka. As of 2012, more than 400 aircraft of this type were operated in the world.

The most common version of the aircraft was the modification of the L-410UVP, in this version, the aircraft had a reduced take-off and landing distance. The abbreviation UVP means “short takeoff and landing”. The aircraft of this modification first took to the skies in 1976. Initially, the machine was equipped with the usual set of aviation equipment of the Soviet-Czechoslovak production. The model differed from its predecessors in the increased size of the wing and vertical tail, elongated fuselage, the use of spoilers and more efficient engines.

The small passenger aircraft L-410 "Turbolet" was designed by the designers of the company "Let" in 1966-1967, the project was headed by Ladislav Smrchek. It was assumed that this aircraft could be used in a fairly wide temperature range from +50 to -40 degrees Celsius. Czech specialists were guided by the Soviet terms of reference and took into account in advance the difficulties of the climatic conditions for operating the aircraft in the USSR, which was to become the main customer of the aircraft.

In total, by the end of 1978, 100 L-410M / MU aircraft were purchased in the USSR for the Ministry of Civil Aviation. In the Soviet Union, "Turbolets" replaced Antonov's famous "maize" carriers, which transported unpretentious Soviet passengers on the air pits of local airlines. At the same time, it is worth noting that the pilots who were “transferred” from the An-2 to the L-410 perceived the newcomer in two ways. On the one hand, the Czech aircraft had a lot of advantages. Firstly, he had 2 engines, he won 2 times in safety. The plane had a set of modern navigation and radio equipment, a high level of comfort was provided for passengers ... But, on the other hand, for the pilots of the civil air fleet, the An-2 always remained a free "gasoline breadwinner" of their personal Zhiguli and Volga , while the Czech plane flew on kerosene. And in operation, the An-2 was a more unpretentious machine. To be more precise, the flight technical personnel treated the issues of operating the Soviet An-2 much easier. In general, it was considered very prestigious to transfer from the An-2 to the Czech L-410.

Currently, the Czech Republic is producing a version of the L-410 UVP-E20 aircraft, which can be equipped with analog or digital avionics (at the customer's choice), the TCAS mid-air collision avoidance system and an autopilot. The L-410 UVP-E20 aircraft received the AR IAC certificate.

The development of the L-410 aircraft began in 1966. The first sample flew into the air after 3 years. He transported the first passengers at the end of 1071. This flight was operated by the Czechoslovak company Slov Air. The following year, Czechoslovak developers transferred 5 cars to the USSR. Despite the good flight characteristics, work on improving the aircraft continued. So, already in 1973, the L-410M, equipped with an engine made in Czechoslovakia, took off.

The next, more advanced modification of the L-410UVP appeared in 1979. It was distinguished by large wings, vertical tail, and a longer fuselage. This modification became a serial model.

But her improvement continued. In 1984, the L-410UVP-E variant appeared, featuring more powerful engines. After 2 years, the aircraft, which received a certificate in the USSR, again received a different, powerful engine.

In the 90s, due to a decrease in demand, aircraft production was reduced to 2-5 per year, although before that they were produced at 50 per year. This continued until 2008, when 51% of the shares were bought by the Ural Mining and Metallurgical Company. The production of aircraft increased and reached 11 in 2013. There was no further increase. Currently, most aircraft are in poor condition. But some of the L-410s continue to fly.

This small aircraft used and enjoys a certain popularity. It has been and continues to be operated, although without the former intensity, in 40 countries. On local airlines, it has proven itself well even in Australia and Greenland.

In Russia, L-410 is rarely used, since a significant part of local flights are not operated. These aircraft are available in the fleets of KrasAero, Orenburg and the PANH airline, located in Buryatia. Interest in the aircraft is shown in the Ministry of Transport and the Ministry of Industry and Trade, as well as in some regions that have large territories with an undeveloped road network.

Although the developments used in the L-410 are far from new, a number of innovations made to it in subsequent years make it possible to operate the aircraft with an efficiency no less than existing modern designs. Due to the use of new engines, its flight range has been significantly increased, and various cabin options allow it to be used not only as a passenger aircraft. The advantage is the ability to use this aircraft at temperatures from minus 40 to plus 50 degrees. It should also be clarified that the L-410 can land on an unpaved runway.

Salon of the liner: comfortable and uncomfortable places

Although the cabin of this small aircraft is designed for passengers traveling short distances, it has every possible comfort. Armchairs are not much different from those installed in large airliners. Of course, sitting in them for a long time will be tiring, but this machine does not perform long-haul flights.

Armchairs are arranged in 7 rows. But there is an option in which there are fewer rows. In this case, the number of seats is not 19, but only 17. In the first option, those in the first row are recognized as the best places. There are only 2 of them here: A and C. They are located on the left and right at the windows. For a tall passenger, the most comfortable seat is B, located in the second row. There is no chair in front of him, which makes it possible to place the legs quite comfortably.

During the flight, the noise of running engines is clearly audible in the cabin. But it does not differ in high volume. So that passengers can talk to each other, as they do in any mode of transport. There is no need to shout in the salon.

A well-installed heating system ensures a comfortable temperature during the flight. So even in winter you can stay here without warm jackets, coats, fur coats. They are easily placed on luggage racks. These shelves are enough for all passengers, but you can’t place something voluminous there.

It is also difficult to accommodate passengers with large bags. Going on a trip with more or less solid luggage, you should place it in the luggage compartment. There are two such compartments in the aircraft. Although they do not differ in large volumes, there is enough space for everyone.

Usually, when flying, many passengers simply do not know what to do so that the travel time passes unnoticed. In the cabin of this aircraft, passengers in the front rows are usually engaged in monitoring the work of the pilots. There is no blind door between the passenger compartment and the cabin, so it is easy to observe what is happening in the cabin.

Since the flights are carried out at a low altitude, usually not exceeding 3 thousand meters, the pictures floating below are clearly visible through the conveniently located windows. The advantage here is that you can look at the ground, being in any row. The view is not covered by the wings located above the windows.

Of course, one should also mention such convenience in this small plane as a toilet. It is located in the tail section. Of course, for those in the sixth (seat A) and seventh (seat B) rows of passengers, such a neighborhood brings inconvenience. However, the toilet door does not open towards the passage, but towards the front door, and there are few passengers in the cabin.

A feature of the cabin is a narrow passage. It is almost impossible for two people to pass each other. But there is no movement towards each other in the plane. In addition, flight attendants with carts do not appear in the aisle, as happens in large aircraft.

In the following diagram of the cabin of an aircraft designed for 19 passengers In the diagram below of the cabin of an aircraft designed for 19 passengers, the numbering, as usual, starts from the left. The seating order is A, B, C. The number 5 indicates the toilet, the number 11 indicates the luggage compartment.

Does the aircraft have a future?

In recent years, measures have been taken to revive small aviation in Russia. This also applies to the L-410 aircraft. Workshops for its production are being installed in the Titanium Valley, where UZGA decided to place them. The commissioning of production facilities should occur in 2018. It is envisaged to produce aircraft not only for civil aviation, but also capable of performing a number of other tasks. Including will be produced vehicles intended for the armed forces.

In all cases, the latest technologies will be used in production, which will make the aircraft safer and more comfortable. The passenger version of the L-410 will be used on intra-regional lines, as well as for communication between cities in different regions with an insignificant passenger flow between them.

Conclusion

Available information suggests that the L-410 aircraft has not exhausted the possibilities for continued operation and further improvement. Its special advantage is the ability to take off and land, where other airliners cannot do this. The ability to fly at high and low air temperatures allows you to use it in a variety of climatic conditions.

The number of passengers carried, although not as large as that of larger liners, however, in most cases it is sufficient for passenger requests, since the aircraft is usually used on intra-regional lines, or on routes between cities that are not so far apart. During flights, passengers are in conditions that are almost not inferior to those existing in large airliners. Further improvements will make it possible to make these conditions more comfortable.

Calculating the cost of a taxi to the airport

The Let L-410 Turbolet airliner was born in the late 60s thanks to Czechoslovak aircraft engineers from Let. This aircraft was to be used only by local airline companies, the main customers of such aircraft were the USSR. Also, Let L-410 Turbolet was delivered to Bulgaria, Brazil, Hungary, East Germany, Libya, Poland.

The aircraft began to be used for commercial purposes only in 1973 and acquired several interior modifications:

1. L-410A - in this model there was a new engine PT6A-27.
2. L-410M - This model had a more powerful M-610 engine installed.
3. L-410UVP - in this modification, the wings, fuselage and keel were lengthened, made of steel in 1979-89.
4. L-410UVP-E - This model had five-blade propellers installed, and two fuel tanks with a volume of 200 liters were also added. They were mounted at the ends of the wings.

If you delve into history, then the melon plane was rebuilt for military aviation, it served not only for transporting soldiers, but also for special purposes. In total, about 1100 airliners of various configurations were produced, most of the aircraft were sent to the Soviet Union, there are up to 800 L-410 aircraft. Serial production of the Let L-410 Turbolet airliner was discontinued in 1991, despite this, several custom-built aircraft were produced in the 2000s.

Also, due to its shape, the plane was nicknamed "Cheburashka" Because of its large blades located above the cockpit, it looked like a well-known hero of the Soviet cartoon.

Characteristics of Let L-410 Turbolet

The length of the aircraft was only 14 meters, and the wingspan reached 20 meters. He could lift up to 6600 kilograms into the air. The weight of the aircraft itself was 4,150 kilograms. The maximum flight range reached 1540 kilometers, but at full load it decreased significantly. The airliner has only one economy class, it has 19 seats, the width of the cabin itself is 1.92 meters.

The aircraft is very well spoken about, the percentage of positive reviews about this aircraft is 85 percent, and 15 percent of neutral reviews, but not one of the passengers speaks negatively about it, which indicates the high quality of the aircraft and the flight in it.

The cabin of the aircraft Let L-410 Turbolet

The seats in this aircraft are arranged according to the 2 + 1 principle, which automatically makes the single row more comfortable than others, but the double row is perfect for flights in a company or for those people who cannot be without communication throughout the flight.

There are only two crew members in the airliner, a pilot and a flight attendant, due to the small number of passengers, she manages to pay attention to all her passengers, leaving no one unattended or without providing any service.

Due to the fact that the wings of the aircraft are located at the top of the side, all passengers can enjoy the views from the windows without any difficulty, and they will not block the view from the window of the aircraft wing or other parts of it.

If you look at the aircraft diagram, you can immediately determine the best places, the aircraft diagram will be presented below. You can verify this for yourself. There are only 6 rows on the plane, but the seats under the letter "A" located on the right side of the plane have only five seats.

Not the best places

Row 1. It seems that it can be called the best series, but if we consider this series in detail, then it cannot be called the best series. Firstly, it is located close to the technical room, the light can be constantly on in it, and various noises can be heard from there during cooking or during the use of other equipment. Also, seat B in this row is located next to the partition, which makes it impossible to calmly stretch your legs and enjoy the flight.

But this row also has pluses, you will always get food first, and thanks to this you will have a large assortment to choose from. You can also safely get to the kitchen to ask for something. And the main advantage of the first rows is that you do not have to constantly collide with other passengers, and you will be able to get out of the aircraft cabin very first.

Row 6. It has only two seats, it is located on the walls, which may make it impossible to recline the seat in order to fly in a comfortable position. Also, you will have to watch the constant circulation of people to the toilet, it is possible that there will be a queue, and one of the passengers may lean on your seat, which will cause some discomfort. Also, unpleasant sounds can be heard from the toilet, but this is not the worst thing, it can come from the restroom, an unpleasant smell that you have to put up with throughout the flight.

Row 5. The main disadvantage of this row is that it is located near the restroom and along the way people will accumulate near your seats waiting for their turn to go to the toilet, and an unpleasant smell can come out of the toilet, which will cause a lot of inconvenience during the flight.

Best Places L-410

The best places include rows from the second to the fourth, the second row has all the privileges of the first row, but the estimates and noise from the technical room will not cause you such inconvenience as the first row. The third and fourth rows are located in the middle of the cabin, the technical rooms will not be able to disturb their harmony during the flight. Since the toilet is far enough from them and the queue simply does not reach them, and even more so the sounds and smells from the restroom. The same can be said about the kitchen, estimates and sounds also do not reach them, thanks to this they can safely enjoy flights in the L-410 airliner.

All-metal high-wing L 410, mass-produced, is equipped with two GE H80-200 turboprop engines and is designed for the transport of 19 passengers, cargo or for specific purposes. Aircraft of the L 410 family are operated in more than 50 countries on five continents, most of which were delivered to Russia, as well as to Africa, Southeast Asia, South America and Europe. To date, more than 1,300 aircraft have been produced. Currently, the L 410 UVP E20 model is being produced, which is the most advanced version of the previous L 410 series of aircraft, known for its outstanding properties and has a number of advantages:

• Lowest operating and maintenance costs in its category
• Unsurpassed endurance and proven reliability in extreme conditions

Particularly appreciated is their massive and robust construction and ability to operate in extreme climatic conditions in the temperature range from -50°C to +50°C. The strong fuselage of the aircraft and the unique design provide ample opportunities for its operation both in the hot heat of the deserts of Africa and Latin America, and in the coldest regions of the world.

Aircraft L 410 feel at home both when operating in the Sahara desert and in the Siberian tundra. Aircraft have already proven reliable in operation in an exceptionally wide range of climates, from the dusty and dry African savannas to the rain forests of Latin America, as well as when taking off from "sea level" or hot high mountain areas. Aircraft are already successfully operated in many countries and regions around the world.

With its unique undercarriage, the aircraft can be operated anywhere, and it only needs a few meters of strip with a minimum strength of 6 kg/cm2 (85 lb/in2), i.e. it can also land and take off from moisture-soaked short grassy airstrips.

The L 410 UVP-E20 is certified under FAR 23 (Amendment 41) in its category and has received type certificates in the Czech Republic, Denmark, Germany, Sweden, Indonesia, the Philippines, Australia, Argentina, Brazil, Russia, Cuba and Chile. After the establishment of the European Aviation Safety Agency (EASA) the aircraft received a full type certificate EASA and FAA(US Federal Aviation Administration). The aircraft has also been approved for operation in many other countries such as Algeria, South Africa, Kenya, Tanzania, Uganda, Tunisia, Colombia, Venezuela, South Korea, India, etc.

The L 420, which is an FAA certified variant of the L 410 UVP-E20, is certified under FAR 23 (Amendment 41) directives and received type certificates in the Czech Republic, USA, Australia and Indonesia, as well as a full EASA type certificate.

Aircraft L 410 represent an ideal combination of first-class technical parameters and economic operation for the transport of passengers and goods over short and medium-long distances.

- short-haul aircraft for regional airlines, produced in the Czech Republic since 1969.

The Let L-410 Turbolet was developed in the mid-1960s specifically for 500-800 km airlines that needed a roomy, economical and low maintenance aircraft. In general, in terms of takeoff and landing capabilities, the aircraft required characteristics similar to those of the AN-2.

The Let L-410 Turbolet made its first flight in April 1969.

The margin of safety that the designers invested in the aircraft allowed the Let L-410 to take off and land on unprepared airfields and unpaved areas.

Salon Let L-410 is spacious and equipped with large round portholes and acceptable soundproofing. Passenger seats are located in a 2 + 1 configuration.

The liner is capable of carrying up to 19 passengers over a distance of 990 to 1,500 km.

Over the years of production, the aircraft has been constantly upgraded in accordance with the requirements of the time. Today, the aircraft continues to be produced.
