Antonov An-24. A photo. Video. Driving compartment. Characteristics. Reviews.
The twin-engine, turboprop Antonov An-24, was designed for passenger traffic and is designed for use on domestic routes.
In 50-th year 20-century noted active development of aviation technology, at this time, and there were more advanced gas turbine engine. For this reason, the leadership of the former Soviet Union to the problem designer DC was set Antonov to establish a qualitatively new military transport aircraft model, called AN-24. Despite this, priority is also given to the passenger version of the aircraft.
History of An-24
The prototype aircraft AN-24 made its first flight in the autumn of the year 1959. In the early 60-year one of the new "ANTONOV" was transformed into a transport version called An-24T. But all the characteristics of the cargo it was more than the transport plane. It did not provide a special loading ramp or at least the cargo hatch. Loading in the plane could be made only through the hatches, which were located in the side of the hull. Yet transport model different from the standard reinforced floor in the cargo area, and was also an additional hatch on the right side, and through which the load must be carried out.
Summer 1960-year designers has been designed and developed version of AN-24, which had an extra engine in the right nacelle, and the most important thing is that it was a jet engine that had traction in 900 kg. While using the engine made possible the qualitative improvement of aircraft characteristics during takeoff.
Transport model has successfully passed state tests in 1963 year, but this model had too many complaints from the transport aircraft commanders.
The main problem is the lack of cargo hatch in the rear of the plane. For this and many other reasons it was decided to build a new machine that would be able to meet all requirements. For the construction of new transport AN-24 Antonov Design Bureau started winter 65 years. The basis of a new car was taken by An-24 prototype. new unit tests were carried out over two years by 1965 1966 years. When testing a lot of attention paid to the quality of landing humans on board the aircraft. Serial production of the new transport aircraft began at the end of the year 66 the Irkutsk aircraft plant.
The release of the AN-24 1979 lasted until the year was made more than 1200 machines, and more than 1000 units were produced at the Kiev plant "Aviant." The aircraft produced and China, but under its name to Xian Y-7. Soon after the model aircraft has become very popular in all the airlines in the territory of our country, he served more than 450 different airlines. Its popularity has spread over the territory of our country, because this machine 25 exported to countries across the globe.
Features and characteristics of the AN-24
An-24 had excellent flight characteristics. All aircraft maintenance can perform 7 people in flight, namely: aircraft commander, navigator, co-pilot, flight engineer, radio operator and two flight operators. Two turboprop engine was installed on this machine, which had more than 2,5 thousand horsepower each. They were fitted with screws with four blades, which had a diameter of almost 4 meters.
Fuel is supplied to the motors with 4 tanks, which are located in the aircraft wings, each wing has two tanks that provide the appropriate engine also possible to connect all the tanks in the same system. When using two motors optimally under load 5,5 ton aircraft can travel thousands of kilometers. Even in case of failure of one of the engines of the aircraft can continue flying and get to your destination. The aircraft meets the requirements on stability and control, which are put forward passenger aircraft in its class.
The structure of the AN-24 body is all-metal monoplane, where wings were highly placed. The entire body of the aircraft is designed as a pressurized cabin, which is divided into front and rear load compartment, passenger compartment and the cockpit. It also includes a wardrobe, a toilet, a snack bar and lobby. The entire body of the aircraft has twenty windows. In an aircraft emergency exits thought.
Plumage single-fin, which was set forkil. The wing has a trapezoidal caisson type and high elongation. The components of the units are two wing spar odnoschelevye flaps, which are able to deflect. chassis system has been represented by three pillars, which were removed in the body of the aircraft. Each strut has a double wheel on which the brake system installed.
Aircraft maintenance electricity produced two generators that were installed on the engines. They provide a constant voltage to 27 volts, as well as three-phase voltage in volts 36. In the event of an accident or breakdown generators aircraft could be powered by two batteries.
Like many other models of aircraft, the An-24 is equipped with a system that does not allow the fuselage icing. Most prone to icing engine air intakes and wings. To avoid this problem, the designers thought was the air-heating system, which is powered by electricity. In case of depressurization of the plane body was thought system which can provide oxygen to all the people on board.
When designing a special attention was paid to the constructors reliability and easy operation. Both pilots were able to steer the boat, because the management has been duplicated at each of them. This was done in case of failure of one of the control panels. This aircraft model has an electric autopilot, which greatly facilitates the work of the pilots. An Airliner-24 had enough modern and reliable radar equipment at the time.
Passenger model An-24 was designed for the transport of 50 passengers and their luggage for a short distance. As a rule, they were used for local passenger transport. The resource usage of the new aircraft An-24 50 was increased to thousands of hours of flight, the figure was the highest in the entire USSR.
If necessary, the AN-24 may be made more comfortable versions, in which case the number of passengers can be significantly smaller depending on the order. The models of this aircraft can be easily converted into the cargo version or cargo-passenger. Such metamorphoses with cabin You can do very quickly, because the passenger seats are removable.
The advantage of this model is the fact that it can be operated in all seasons, it is possible to embark on a snow-covered, sandy and soggy ground. Takeoff and landing An-24 can carry on a fairly short runways, because it needs only 650 meters for take-off.
This model is different from other high efficiency of flight that allows you to effectively use it even on short-haul routes in 250 kilometers. Especially in the case of airlines wishing to use the services of so many.
Antonov An-24 has rightly become the progenitor of a whole family of aircraft for different purposes. Today, there are more than 40 modifications of this machine.
According to the statistics at the beginning of the year was lost 2014 162 machines AN-24. All the losses were linked to factors such as the plane crash, some machines were destroyed on the ground during the war. As a result of catastrophes of all time use of the aircraft was lost man 2120, 29 of them were on the ground at the time of the crash. Passenger aircraft An-24 33 times tried to steal, these attempts at killing human 4.
Development of the project short-haul aircraft for commuter turboprop, began in connection with the need to replace obsolete IL-14Where used piston engines. This project, under the 32-40 number was proposed Design Antonov bureau in 1956 year.
After approval of the project, in 1958 year, began the development of the aircraft. According to the technical requirements, the projected plane was to be used in a wide temperature range, to land on unprepared airfields and small, to make the flight with a payload of at least four tonnes and have a flight range of at least 500 kilometers.
The aircraft was ready by mid-year 1959. On it were installed two turboprop engines Ivchenko autoionization-24 propeller AB-72.
20 1959 October, the first An-24, under the command of test pilot Lysenko GI, rose into the air. At the beginning of the year 1961 started program of state tests of the plane An-24.
Produced machine to obtain reliable and requires minimal ground support equipment. Aircraft thrust per unit weight, get more than many comparable aircraft of that time. aircraft engines also have a successful arrangement, being on the high-wing, allowing more to protect them, and the propeller blades from foreign debris.
Upon completion of all test flights, 1962 year, the Kiev aircraft plant, the plant now, "Antonov", began mass production of the aircraft for the needs of the airport. The first flight on the serial An-2, with passengers on board, was completed in September 1962 years. A month later, I started operating regular route guidance "Kiev-Kherson" in October 1962 years 2-AN. Direction "Moscow-Voronezh-Saratov" was later added.
Thanks to its sturdy airframe and good operational performance and not demanding a large airfields, aircraft An-24, was adapted not only for passenger flights, but also to perform many minor problems. For example, such as ice reconnaissance, cargo transportation, search and rescue and fire-fighting operations.
On the basis of the original aircraft An-24 the following modifications were made:
An-2A - modification, designed to carry passengers 44.
An-24B - passenger version capable of carrying up to 52 passengers.
An-24R - aircraft variant for signals intelligence needs.
An-24RT - military transport aircraft modification
An-24SHT - HQ version of the aircraft
An-24FK - aircraft variant intended for aerial photography
An-24PP - version equipped devices length analysis of radioactive contamination
An-24PC - search and rescue variant of the An-2.
An-24LP - modification of the AN-2 designed for fighting forest fires.
Driving An interior-24
There have also been produced and are in the projects, and other modifications of the An-24, designed to perform a wide range of other tasks.
Over the entire period of serial production, c 1962 1979 by year produced about 1300-24 An aircraft. In today's time, according to various estimates, in operation it is about a hundred of these machines.
Antonov An-24 also produced in China, c 1984 years, under the designation Xian Y-7. Since 2000 years, China has continued to release a modified version of the aircraft, received the name of Xian MA60. Today, the successor to the AN-24 aircraft became turboprop passenger and cargo aircraft An-140, designed by Ukrainian State Enterprise Antonov "Antonov".
