American engine manufacturer GE Aviation announced the signing of a five-year contract for the supply of M601 and H80 engines to the Czech aircraft manufacturer Aircraft Industries. These engines will be supplied to the L-410-UVP-E20 turboprops being assembled in the Czech city of Kunovice. The Czech company expects the production of this 19-seat twin-engine aircraft for local airlines to exceed 10 units per year in the coming years.

The M601 is already in use on the L-410. The H80 engine is its improved modification, which will allow the aircraft to operate in hotter conditions and at higher altitudes. Aircraft Industries plans to certify the L-410 with the new engine in mid-2012. After that, owners of versions of the aircraft with the same power plant will be offered a remotorization on the H80.

L-410 UVP-E20 - universal twin-engine aircraft Czech production for local airlines, accommodating 19 passengers. Designed for operation on unprepared unpaved, grassy, ​​snowy areas, as well as on airfields with short runways (about 600-700 meters), which, in fact, makes it an off-road aircraft.

The first flight of the L-410 was made on April 16, 1969. The main customer of the aircraft was the Soviet Union. In addition, the L-410 was also supplied to Bulgaria, Brazil, Hungary, East Germany, Libya, and Poland. Despite the fact that the plant is located in the Czech Republic, it considers itself a part of the Russian aviation industry: the grounds for this were laid during its development and long-term operation. As of 2012, more than 400 L-410s are in operation worldwide.

Production site of Aircraft Industries in Kunovice, Czech Republic. The Aircraft Industries plant, better known under the Let Kunovice brand, is located 300 km from Prague. The plant employs 920 people.

The company manufactures the aircraft according to the full production cycle - it has its own lines for surface treatment of materials, paint and varnish production, a machine shop, assembly shops, a design bureau and an airport.

Workshop for the production of parts of the fuselage L-410. The enterprise is expanding and modernizing production - light green equipment is intended for the production of a new generation of aircraft L-410 NG (New Generation).
The production capacity of the plant is 16-18 new aircraft per year. About 80% of aircraft are delivered to Russia. Over the past four years, 35 aircraft have been delivered to Russia.

Production of parts on a CNC milling center of the French company Creneau:

In one half of the building there are two lines for the production of new L-410 aircraft, in the second half there is a workshop for servicing aircraft coming out of service:

At the same time, about 10 aircraft are in the assembly shop. The fuselage, wing, end tanks and tail unit come to the beginning of the line from the paint shop. At the end of the line are aircraft undergoing flight tests and preparing to be shipped to customers. Over the entire history of its existence, the plant has produced over 1150 aircraft of the L-410 family. More than 850 of them were delivered to operators in the USSR.

The AV-725 five-bladed propellers (Avia Propeller) together with the GE H80-200 engine make up the new power plant for the L-410 UVP-E20 aircraft. It has been installed since January 2013 on all new aircraft and is certified by EASA and the Russian AR IAC.

Young people in production are not uncommon, also due to the presence of their own vocational technical school on the territory of the plant. The average age of the company's employees is 44 years:

Work on the GE H-80 engine, given by a representative of a company from the city of Prague:

The final assembly stage takes about 5 months - this is the most expensive part of the production, so within its framework, engines, landing gear and all avionics are installed on the aircraft, where each individual unit can cost 100-250 thousand euros.

The total duration of the aircraft production cycle from the production of the first fuselage components to the completion of flight tests takes a little less than a year.

The cockpit of the aircraft L-410 UVP-E20. The aircraft is fully equipped for instrument flight, has an advanced ground proximity warning system (GPWS) and airborne collision warning system (TCAS II). L 410 is designed in metric system (instead of inches), which is an exception in Western aviation:

This type of aircraft has been used for many years as a graduate for pilot training at the Sasovo Civil Aviation Flight School (Ryazan Region).

The first L-410 aircraft was created in the 60s of the last century by Czechoslovak manufacturers by order of the USSR. It was the Soviet Union that was the main customer for this type of air transport, however, companies from other countries were also interested in this model:

• Poland and Lithuania;
• Bulgaria and Hungary;
• Brazil.

After all, the advantages of the aircraft could be assessed even with the naked eye:

1. Lightness and maneuverability.
2. Ability to land on normal ground.
3. Sufficient carrying capacity and comfort.

These are the characteristics of the new liner. Photos of the cabin of the L-410 aircraft can be viewed on our Internet resource.

Aircraft L-410

The first model of the L-410 aircraft, as noted earlier, was created in the late 60s. The main purpose of the new air transport is to carry out short flights. The capacity of the cabin was to be such that it could accommodate up to 20 people, and the aircraft was to be served by airlines up to 650 km long.

The Czechoslovak manufacturer successfully coped with the task assigned to it, the new model of the air vehicle turned out to be not only reliable and unpretentious, but also multi-purpose, which, in fact, was required by the customer.

Having at your disposal the new kind air transport, the liner began to be used for:

• passenger and freight traffic;
• for the transportation of correspondence;
• for the transport of patients;
• for various scientific research.

The new model of air transport was valued not only for maneuverability, but also for the ability to take off and land in places where there was no runway, which was extremely important when transporting patients or when conducting scientific research.

The first model, called the L-410, took to the skies in the late 60s, however, as the manufacturers noted, the air transport engine was underpowered. Therefore, it was decided to make several changes to the production process, in particular, they affected the engine. So, by the mid-70s, modernized L-410s with a more powerful engine were put into production, 5 of which were transferred to the Soviet Union.

The main customer was satisfied with his order and continued cooperation with the manufacturer, and the first air transport was bought by Aeroflot, the most famous company in those days. You can see photos of the aircraft Let L-410 on the site. By the beginning of the 80s, the Soviet Union had acquired more than 100 models of L-410 aircraft, and was not going to stop cooperation.

The cabin of the aircraft L-410

A variety of aircraft models L-410

The Czechoslovak manufacturer did not stop at his achievements, constantly creating more and more advanced models of liners. The production of the following models was launched:

• L 410 UVP;
• L 410A;
• L 410 AS;
• L 410 M.

The L 410 UVP model was also developed at the request of the Soviet customer; the aircraft differed from its counterparts in the increased wing length and fuselage, as well as in the plumage, made in a vertical design. Such modernization allowed the liner to take off and land at an even shorter distance, which was the main requirement of the customer.

The demand for air transport from the Czechoslovak manufacturer, of course, subsided after the collapse of the USSR, but the Ural Mining and Metallurgical Company helped to save the situation, which 8 years ago bought more than 50% of the shares from the first manufacturer. Currently, the partners are planning to increase the production of aircraft, improve the production process, and purchase new modern equipment.

Air transport characteristics

Technical characteristics of the aircraft L-410:

• up to 14.42 m - the length of air transport;
• up to 20 m - the wingspan of the aircraft;
• 35 m 2 - occupies the wing area;
• 5.83 m - aircraft height;
• 4 tons - weight of empty transport;
• up to 6.6 tons - the maximum weight allowed during takeoff;
• 750 HP on 2 - engine power;
• 335 km / h - maximum speed;
• up to 1500 km - is the range of air transport.

The capacity of the fuel tanks is designed for 1680 liters, the maximum fuel supply is 1300 kg. If the aircraft is fully loaded, it will be able to cover a distance of 1000 km, and for the maximum run it will need only 850 meters.

There are two places for the crew, there are 19 passenger seats in the cabin, the width is 1.9 meters. A photo of the L-410 aircraft will help to get acquainted with the aircraft cabin in more detail. vehicle.

Aircraft L-410 in the sky

What else do you need to know?

Summing up, we can say that the L-410 liner is a reliable, unpretentious and maneuverable type of air vehicle, which has a reduced distance for both takeoff and landing. It is convenient to operate transport in such conditions where it is difficult to take off and land transport. Thanks to a sufficient margin of safety, which was invested by the manufacturers, the aircraft can easily land and take off from unprepared and even from unpaved areas. The spacious cabin, equipped with large windows, has good sound insulation, the passenger seats are located in the position 1+2.

This model is able to overcome about 1300 km, while carrying 19 passengers., and high-quality chassis, made according to a special method, allow the aircraft to land even on wet grassy ground. The liner showed itself well when operating in harsh climatic conditions, the excellent traction characteristics of the engine make it possible to use the aircraft both at high temperatures and at very low atmospheric pressure.

Excellent security parameters allow you to safely transport passengers, deliver cargo in integrity and without damage. Throughout the history of its existence, the liner has been constantly upgraded by the manufacturer, and the production of aircraft continues at the present time.

By joint efforts, manufacturers plan to create more advanced models in the coming years, the engines of which have increased power, the luggage compartment area will increase, the cockpit will be equipped with the latest equipment, including avionics.

In contact with

The Russian Ural 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. Based on this machine, it was created a large number of various modifications of transport, military and special purposes. 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 are ready to purchase several aircraft Khabarovsk Territory. 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 L-410UVP modification; in this version, the aircraft had a reduced takeoff 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.

It is worth noting that the design and production of small aircraft and air taxis in the countries of the Council for Mutual Economic Assistance (CMEA) bloc was the prerogative of aviation industry Czechoslovakia. Czech-made aircraft flew not only in the countries of the socialist camp, but also in Switzerland, Italy, Great Britain, the USA, Australia and other countries of the world. Aero-45, Super Aero-45S and Aero-145 four-seater air taxis, as well as the L-200 Morava, were in particular demand. Therefore, there is nothing surprising in the fact that when the question arose of choosing a small short-haul aircraft for serial production, the choice fell on the Czech L-410, which most fully corresponded to most of the parameters announced in the terms of reference of the State Research Institute of Civil Aviation.

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 the difficulties in advance climatic conditions operation of 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 the famous "corn" Antonov, who transported unpretentious Soviet passengers on air pockets 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, passengers were provided with high level comfort ... But, on the other hand, for the pilots of the civil air fleet, the An-2 has always remained a free "gasoline breadwinner" of their personal Zhiguli and Volga, while the Czech aircraft 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.

In total, since 1969, 1104 L-410s were produced in Czechoslovakia and the Czech Republic. various models, of which 862 aircraft ended up in the USSR. Interestingly, the 1000th Turbolet was produced back in 1990 and transferred to Aeroflot, after which their production volumes were significantly reduced. With the collapse of the CMEA, and subsequently the Soviet Union, the demand for these aircraft dropped sharply. Despite this, Turbosts are still in operation in more than 45 states around the world.

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.

Major operators CMEA countries Options L-410UVP

Universal aircraft for local air lines (IL), which replaced the An-2. The first foreign-made aircraft that entered the domestic air routes. Other names: L-410, Let, Let L-410, Turbolet, Cheburashka.

Description

The development of the aircraft began in 1966. The first prototype aircraft, equipped with a Pratt-Whitney Canada RT6A-27 turbojet engine (2 x 715 hp), began to undergo flight tests on April 16, 1969. opened the Czechoslovak airline "Slov Air" from Bratislava, serving local airlines - by the beginning of 1974, she received 12 aircraft. A total of 31 aircraft were built. Five aircraft (serial No. 720103-06 and No. 720201) L-410A with RT 6A-27 engines, built by the end of 1972 under the designation L-410AS, were transferred to the USSR the following year. Aircraft received Soviet registration numbers from USSR-67251 to USSR-67255. The first of them was brought to the airfield of the State Research Institute of Civil Aviation by the Czech test pilot Frantisek Svinka. The airfield people immediately called the handsome newcomer "Cheburashka". In 1973, flight tests of the L-410M aircraft equipped with the Czech Walter M 601A theater began. L-410M became the second serial modification of the "Turbolet". In total, by the end of 1978, 100 L-410M / MU aircraft were received for the USSR Ministry of Civil Aviation.

In 1979, the production of an improved modification L-410UVP began, which became the main production model. This aircraft differed from the previous versions by an elongated fuselage, increased wing and vertical tail, the use of spoilers and the installation of a Walter M 601 V theater engine (2 x 730 hp). This aircraft passed the certification program in the USSR and was put into operation by Aeroflot. A further development was the L-410UVP-E variant with more powerful M 601 E theater engines. The first flight of this aircraft took place on December 30, 1984. It features improved takeoff and landing characteristics and reduced noise levels in the cockpit. In March 1986 he was certified in the USSR. A modification of the L-420 was developed with a more powerful M601 F theater (2 x 778 hp), increased takeoff weight (6.8 tons) and improved flight characteristics (flight tests of the aircraft began in November 1993).

Starting from 1969, 1104 L-410s of various modifications were built, 862 of them ended up in the Soviet Union. By the beginning of 1992, about 750 L-410 aircraft remained in the USSR.

Modifications

L-410UVP Short-haul passenger aircraft, a modification of the L-410 aircraft, in which the take-off and landing distance is reduced. The abbreviation "UVP" means "short takeoff and landing." The first launch took place in 1976. Produced by the Czechoslovak company "Let". The aircraft is equipped with a conventional avionics complex of joint Soviet-Czechoslovak production. This aircraft differs from its predecessors in its elongated fuselage, larger wing and tail, the use of spoilers, and a more powerful engine.
