The incident occurred during the takeoff of the An-24 passenger plane on the morning of February 4 at the Yakutsk airport. It was reported that during the takeoff attempt, the left engine of the aircraft caught fire. Later, Natalya Shakhurdina, press secretary of the North-Eastern Directorate of Internal Affairs for Transport of the Ministry of Internal Affairs of Russia, clarified that during the take-off run, the An-24's landing gear was prematurely removed, and the plane touched the runway with its fuselage. Thanks to the actions of the pilots, the plane remained on the runway, but the emergency shutdown of the engines led to insignificant smoke in the cockpit.

An-24 is a passenger turboprop aircraft for short and medium-range lines, created at the OKB im. O.K. Antonova in 1959. The flight data and the power plant of the An-24 allow the aircraft to be used in high altitude and wide temperature ranges and to land at small unprepared airfields.

The An-24 is equipped with two AI-24 turboprop engines and one additional turbojet engine RU19A-300 turbojet engine. The power of one engine is 2550 ehp.

An-24 has the configuration of a cantilever monoplane with a high wing position, equipped with large-span Fowler flaps - two-slotted on the outside of the engine nacelle and single-slotted in the wing root. The tail unit is traditional, supplemented on a production aircraft with a ventral keel; fuselage of semi-monocoque type. The hydraulically retractable tricycle landing gear has double wheels on each strut, steerable and swivel nose support wheels, and the pressure inside the tires adjustable in flight and on the ground.

In April 1960, the first of the prototypes of the aircraft took off.

Serial An-24 aircraft began to be used by Aeroflot in 1962, and in September 1963, the first 50-seat An-24V began to operate flights between Moscow, Voronezh and Saratov.

Subsequent versions of the aircraft included:

An-24V Srs II - 50-seater passenger aircraft, converted into a cargo-passenger, cargo or administrative aircraft; An-24RV - similar to the previous version, but equipped with an additional accelerating turbojet engine with a thrust of 900 kg (1985 hp), which serves to start the engines autonomously and increase the power-to-weight ratio of the aircraft during takeoff; AN-24T - cargo aircraft with a hatch in the lower rear part of the fuselage, with two ventral keels on the outer sides of the cargo hatch, with a cargo winch and a conveyor; An-24RT - similar to An-24T, but with an accelerating turbojet engine, like the An-24RV; An-24LP - forest fire option.

Flight performance of the An-24:

Crew - 4 people.
The maximum number of passengers is 52 people.
Cruising speed - 450 km / h
The maximum flight altitude is 6000 m.
Takeoff run - 650 m.
The length of the run (with a landing weight of 20.5 tons) is 590 m.
Time to climb to 6000/8000 m - 15/26 sec.
Aviation fuel consumption in cruising mode - 0.92 t / h
The maximum take-off weight is 21800 kg.
The maximum landing weight is 21800 kg.
The flight weight is 14,400 kg.
The empty weight of the aircraft is 13920 kg.
The maximum weight of the cargo is 5500 kg.
The maximum fuel capacity is 4790 kg.

One of the most popular aircraft developed by the Antonov Design Bureau is the An-24. Even in spite of his considerable age, today he can often be found flying short-haul flights in the territory of the CIS countries. Soviet aviation is rich in aircraft, but this is one of the most popular passenger airplane models among Antonov's cars.

It is a pleasure to operate this model for airlines, since there are no problems with maintenance and spare parts. Takeoff and landing of the liner can take place in extreme conditions and places where foreign Boeing or Airbus models will never be able to land.

An-24 is a short-range passenger aircraft. It is equipped with two turboprop engines. Engines manufactured by the Ukrainian company Motor Sich were designed by the Ivchenko-Progress Design Bureau. It was produced for almost 20 years from 1962 to 1979. During this time, more than 1300 pieces of An winged aircraft were produced.

The AI-24 and AI-24T turboprop engines were installed on the liner. Due to the location of the wings slightly above the fuselage, the engines are located at a considerable distance from the ground, which allows the aircraft to operate on unpaved, dusty and even ice-covered runways. Can be operated at minimum temperatures in northern latitudes. This characteristic of the ship and its engines made it a very popular aircraft vehicle.

An aircraft and their modifications

• An-24. The very first variation of the model;
• An-26. A cargo version of the aircraft for military purposes. Installed special equipment for loading and unloading;
• An-30. Special apparatus for reconnaissance purposes;
• An-50. Airplane project on which 4 engines were installed;
• Xian Y-7. Chinese modification for the country's domestic market. Produced for almost 15 years. Produced about 75 units;
• Xian MA60. Improved modification Y7. Manufactured by Xi'an Aircraft Company since the 2000s.

Specifications

The aircraft can fly up to 1,850 kilometers with a cabin capacity of 48 to 52 passengers. The crew consists of 3-5 people. The cruising speed is 460 kilometers per hour. The average flight altitude of the liner is 7000 meters.

Airline use and number in operation

It is difficult to establish how many An-24 aircraft are still in operation. However, they are often found not only in the post-Soviet space, but also abroad. The main civil operators are:

• Kazakhstan, 7 different modifications from the “Southern Sky” airline;
• Democratic People's Republic of Korea, 5 units from Air Koryo;
• Russia. Airline "Turukhan" - 16 units, "IrAero" - 9 units, Alrosa - Mirninskoe AP \u200b\u200b- 3 units, Yakutia - 6 aircraft, KhabAvia - 3 liners and Pskovavia retained 2 vessels.

An-24 aircraft cabin plan

The cabin of the An-24 airliner is able to accommodate the number of passengers from 48 to 52. The most common and frequent arrangement of seats for 48 passengers. There is only one configuration - a single-class economy class scheme.

Note! There is one toilet and a kitchen on board. Luggage is stored in the forward fuselage just behind the cockpit. The luggage compartment is fenced with a special partition.

Since the age of flying models is already very solid, the cabins may seem outdated for travelers. However, they are quite spacious, comfortable and have everything you need. Good access to the restroom is possible from the seats near the windows, since there is a large distance between the seats. Luggage racks are located above the passengers' heads in a standard pattern. It is possible to put carry-on luggage there.

The layout of the An-24 in a single-class configuration for 48 seats

Rows are numbered in letters, from A to G. Where rows A and D are installed near the windows, which guarantees a good view for those who like to admire the scenery or take a photo. Accordingly, rows B and C are located at the central aisle, and this allows you not to disturb your neighbors if you need to go to the toilet.

In the An-24, the cabin layout is standard for this class. There is a central row in the middle, it is wide enough so that you can easily miss other passengers. The seats are arranged in two rows on each side of the fuselage. Wherever a passenger sits, he will have only one neighbor, which is very convenient.

Important!It should be borne in mind that the An-24 salon was produced in the seventies, so there are no entertainment systems, screens, and sockets for charging laptops and mobile devices. You need to take care of charging your gadgets in advance, before boarding.

Comfortable and inconvenient places

According to the presented diagram, you can consider in detail which places are the most convenient, and which ones are the other way around. It should be borne in mind that any seat in each row will be quite noisy, since the aircraft is old. However, there are places with the lowest noise levels.

Seats in the cabin, their description and comfort:

• Rows 10, 11 and 12 are located at the rear of the passenger compartment. There is also a toilet and a kitchen, which can cause concern for passengers sitting here. Extraneous odors and noises will be felt, and this causes discomfort. There may be queues in the toilet. People sitting at the aisle will be constantly disturbed by the passengers going to the toilet and the crew delivering onboard food. Passengers with children are not recommended to settle in these rows, as the child may start to be capricious. Another disadvantage of the seats in the back rows is an increased feeling of turbulence and a lot of vibration.
• The 12th row is the last, the chairs may not fold out completely or at all, since there is a partition at the back. However, the rows at the end of the fuselage have their advantages, as they are the least noisy due to the range from the engines.
• Rows 4 through 8 are the noisiest as they are located directly under the fenders with the motors attached to them. The fenders and engine block the view. Lovers of landscapes and those who want to take beautiful shots are not recommended to occupy places at the windows.
• The second and third rows are comfortable for travel, you just need to consider a few things. If you need to relax calmly, then it is recommended to choose places near the windows, then neighbors who need to leave will not be disturbed. Also, these seats are suitable for lovers of a good view, because there is nothing stopping you from admiring the views from the window.
• The first row can be safely called the most comfortable, since it provides the greatest amount of free legroom and the absence of passengers in front. In front of the row, at a fairly large distance, a partition is installed, which separates from the technical rooms and the cockpit. Recommended for traveling with a child, the availability of free space allows you to put a stroller here.
• The rest of the seats are standard and have no special pros and cons.

Note!Due to the small number of seats and the limited choice of the most comfortable seats, it is recommended to book tickets in advance.

Long years of use of the airliner made it possible to test the plane for strengths and weaknesses and convenience for travelers on the personal experience of passengers and crew. Subsequent releases of various modifications made it possible to modernize and improve the vessel, if not to perfection, then to a quite good level of comfort for cruising. The ability to fly to hard-to-reach regions without suitable runways made it indispensable for the regions of the Far North, where climatic conditions do not allow the use of ships of another manufacturer.

The interior of the liner has proved itself quite well over the years of use, it is spacious and practical, but has long been outdated. The lack of sockets for charging mobile devices and entertainment systems makes the flight monotonous. The twin seating arrangement reduces the need to disturb neighbors to access the center aisle. For those who like to take photos for social networks, windows are suitable, but it is necessary to choose the first rows so that the wings do not interfere with the view. And passengers with children are advised to choose the first row due to the large free space. It is definitely not recommended to book seats in the last rows, since these seats are associated with many inconveniences, passengers there will be accompanied by constant noises and queues to the toilet. It is also advisable if you have a large amount of hand luggage, take the luggage racks as soon as possible, since the number of places there is limited.

An-24 is a twin-engine passenger turboprop aircraft, built for the needs of local airlines, medium and short distances. Developed in the design bureau. O. K. Antonova. In the NATO classification it appears as "Cox". The people also have a good-natured nickname "Nastenka".

Although this plane has small dimensions, it is not devoid of a luggage compartment, a toilet and even a kitchen. On its board, the An-24 can carry up to 52 people in one flight (not counting 3-5 crew members) over a distance of up to 1,850 km.

An-24 development history

The active development of aircraft construction in the Soviet Union, as well as the appearance of gas turbine engines, in the late 50s exacerbated the need to build a new aircraft that would be cheap to manufacture and notable for unpretentious operation. This was supposed to be the An-24, which was to replace the outdated type of aircraft for the nearby highways Il-14.

At the end of 1957, a government decree was issued on the construction of such a machine.

The implementation of the project in 1958 was entrusted to the team of aircraft manufacturers of the OKB im. O. K. Antonova. The designers were faced with the task of creating an aircraft capable of flying up to 400 km at a speed of over 450 km / h and carrying a load of 4 tons. At the same time, it was required to pay due attention to the following aspects:

• ensuring flight safety;
• increased efficiency;
• ease of use;
• long service life of the structure;
• the ability to operate at airfields of limited size;
• the ability to land aircraft on unequipped runways.

Project implementation

By 1959, such a machine was built. The aircraft manufacturers managed to create an aircraft that met all the requirements of that time.

One of the most important parameters of the An-24 was its versatility. If necessary, the board could be converted for various needs. To transform the standard type passenger compartment into a more spacious and comfortable version or into its cargo modification, it was necessary to simply dismantle the seats and interior partitions.

In the built aircraft, excellent take-off and landing qualities were also realized, which, together with the advanced chassis design, made it possible to use the machine on runways of all types of surfaces under any climatic conditions. An important nuance was the short takeoff distance of the aircraft, which was only 650 m. This was enough for its operation at small airfields.

An innovative highlight of this project was the first use of the glue-welded method of joining the aircraft skin. This solution was invented by academician B.E. Paton. Its essence was that the sheathing sheets were welded with points, and after the seams were fastened with an adhesive mixture. This technology greatly simplified the construction of the aircraft, increased the durability of the structure and significantly reduced its cost.

Step into the sky

An-24 made its first flight on October 20, 1959. For more than two years, the car has been tested at factory and state testing grounds. It was only in 1962 that the liner received a recommendation for serial admission. The aircraft was built in Kiev, and later on at aircraft factories in Ulan-Ude and Irkutsk.

The debut passenger transportation took place in September of the same 1962. By the end of October, An-24 was deployed on the Kiev-Kherson route. Since the middle of the 63rd year, the An-24 has provided air passenger traffic between Voronezh, Saratov and Moscow.

Over time, this type of aircraft gained more and more popularity and began to fly in various other directions. A machine with such remarkable technical characteristics soon began to solve the problems of local transportation not only in our country, but also abroad.

Serial production of the An-24 was completed in 1979 and in total amounted to more than 1200 machines. However, this liner is still actively operated in Russia and other countries of the world. This model was very much to the liking of the leadership of the PRC, where now it not only provides flights, but is also built under license and designed in its other modifications.

1938 - the Igarskoye Aviation Enterprise was created as part of Glavsevmorput. The airline to Krasnoyarsk is assigned to the Civil Air Fleet, and all lines from Igarka to the North are assigned to Polar Aviation.

In 1946. with the organization of high-latitude air expeditions "North", a comprehensive study of the Central Arctic was resumed, air expeditions in specially equipped "flying laboratories" with landing on drifting ice became the main means of researching hard-to-reach regions of the Arctic Ocean.

An-24 is an aircraft for transporting passengers. Purpose: operation on lines of short and medium length. Over the years of its serial production, 1200 aircraft have been designed. Since 1960, they have been effectively used for flights in Russia and the CIS. The model is named after the aircraft designer O. Antonov. According to NATO classification, it has the name "Coke" or "Coke".

Interesting! People call the An-24 aircraft "Nastenka".

The history of the aircraft

In 1957, at the OKB im. O. Antonova began developing a new aircraft. It was planned to operate on short-haul airlines. According to the established plan, the An-24 aircraft was supposed to provide transportation of passengers with a total load of up to 4000 kg. At the same time, the distance that he could fly should not exceed 400 km.

Interesting. Initially, the aircraft was equipped with AI-24 engines. They are not very powerful, but they were able to provide sufficient flight performance.

An-24 made its first flight in 1959. In the 1960s. carried out state factory tests of the airliner. Based on the results of the checks carried out by the government of the USSR, it was decided to start serial production of aircraft.

In 1962, the first copy of the An-24 made a commercial flight with passengers on the Kiev - Kherson route. It went well. Since then, the aircraft has been the most sought after in commercial airlines.

Production of the liner continued until 1979. The following countries received a certificate for assembly of the device: USSR / Russia, Ukraine and China. Chinese model An-24 - Xian Y-7.

Popular modifications of An-24
