Antonov An-22

 

Soviet designers have developed a heavy cargo aircraft model An-22, which was equipped with turboprop engines. In literature, the second name "Antey" is often found, and for the codification of NATO it is designated as Cock, which means "Rooster". This device became the first wide-body aircraft of the USSR, which could lift cargo in 60 tons. At the time of creation, this was a record among all cargo planes in the world. It was also the largest truck in the world with turboprop engines. For the first time, An-22 took off in 1965. For all time of a serial structure 68 cars of the given type have been made. At the moment it is used in the territory of Ukraine and consists of the Russian Air Force.

History of the AN-22

An aircraft-22 project is the brainchild of the Antonov design bureau, chief designer of this development has been appointed AY Belolipetskii. In the initial stages of designing the machine designated as a "product 100». The first study was initiated to 1960 years.

An interior-22

In the development of the cargo compartment designers take into account the size of the military and civilian equipment, which could be transported according to the liner. The cargo compartment is initially calculated on transportation of cargoes weighing up to 50 tons. To reduce roll dvuhkilevoe unit was involved in the turns. It was also considered the possibility of landing on airfields with unpaved. For this was worked out multiwheel chassis system, which was equipped with pneumatics with low pressure.

The device is planned to be equipped with four-engine turboprop type with the designation SC-12MV. These units were equipped with screws Model AB-90, which have a diameter in 6,2 meters.

An-22 cabin

In the middle of summer 61 was held session of the commission, which approved the draft layout of the AN-22. manufacturing of prototype was launched two years later the machine, which was completed in the early summer of the year 1964. Flight testing of the device was launched in August 18 64 years, it is the time machine and dubbed as "Antaeus." The first AN-22 made separation from the runway in February 27 65 years at the Kiev airport. The machine is controlled crew of six and a test engineer. The general public "Antey" was presented to the world air show in Le Bourget.

An-22

Serial production of the AN-22 engaged in Tashkent aircraft plant. In the Air Force first machines began to arrive at the end of the year 1969. A full-scale manufacturer engaged to 1976 years. During all this time 68 machines of this class were produced, among which there were many modifications to perform certain tasks. According to official data, in the year 2010 7 were in operation of machines of this type, and even 18 were saved.

Features An-22 constructions

The machine is made by vysokoplana scheme with four turboprop engines. The fuselage is equipped with a two-keel fins and tail section has a large cargo door.

An-22 cabin

The housing is made of stringers, beams and frames, which are integrated into a single structure.

The whole plane is divided into four sections:

  1. The nose part is completely sealed, it is cockpit, which consists of two decks. In the lower compartment cab is a place navigator, behind him are two passenger cockpit. The upper part of the cabin is designed for the rest of the crew of the machine. The upper deck also has three cockpit seating. When emergency crews can carry out the evacuation through a special sloping tunnel.

  2. Average unit department presented the cargo cabin, which is equipped with a grooved floor, made from durable titanium alloy. The aircraft has a ramp that allows unloading works with both the land and from the platform.

  3. The tail portion is formed in a sealed circuit, it includes the cargo hatch and the end of the cargo hold. This part of the unit ends a ramp, which consists of two flaps.

  4. The last section of the body is the ending of the fuselage.

An-22 doors

The wings are made on the caisson type and have the shape of a trapezoid. The wing consists of seven separate components, namely: the center section, two sections and four detachable element of the middle part. At the rear edge of the installed ailerons and servo tab. Also the rear part of the wing has over its entire length a slit type flaps. On the middle part of the wing mounted engines.

An-22 blades

The feathering of the tail has a cantilever structure of the circuit and is made up of a stabilizer and elevator. It also has two keel with rudders flight. The structure consists of two keel spar and ribs to the panel. All rudders are made of the control of the spar and the servo.

An-22 panel

The chassis system on the An-22 airplane is represented by three pillars, among which two main and one bow control tower stand out. The structure of the main supports includes three racks with double wheels, which have a braking system and an amortization system. Racks have a lever scheme of the suspension structure. Release of the pillars provided a hydraulic system, represented by hydraulic cylinders. Two brake wheels are also installed on the bow support. A feature of the chassis system is the ability to produce racks both simultaneously and alternately. All wheels are pneumatic with low pressure.

An air-22

The power plant "Anthea" presented four-engine turboprop type, which is denoted as NK-12MA. These motors drive the huge screws brand AB-90. Each engine delivers power on takeoff in 15 thousand horsepower. Due to the sophisticated design of the wing and the power plant has been obtained 45% airflow wing screws. An-22 equipped with huge soft fuel tanks, which could fit in 127 thousand liters of fuel. For oil systems were installed on tanks 200 liters, wherein each of the motors.

On the basis of the standard An-22 was developed a number of modifications that have been made taking into account the wishes of the customer.
