An-28 a light aircraft with short takeoff distance, it is equipped with two engines, gas turbine type. Its main task is to transport passengers over long distances, as a rule, it is used on local airlines. It is designed to carry only 18 passengers or can be used as a transport ship carrying capacity in 1500 kilos.
This model of the passenger aircraft was developed in the design Antonov bureau in Kiev. The basis of the new model was taken as its predecessor - the AN-14. The main task of the designers was to develop a brand new passenger plane, which was supposed to replace the old model airplane An-2. For the first time the new An-24 He broke away from the web in November 1973 airfield in the town of Svyatoshyn.
History of the AN-28
At the end of the year 1958 in Design Antonov bureau was designed multi-purpose twin-engine Antonov-14, or, as it was also called "Bee". But the possibility of this model have been limited by the fact that it is equipped with low-power motors. Both power plants are able to produce only 600 horsepower. To improve the "Bees" features has been applied installation of more powerful engines up to 810 horsepower each. This model has also been increased fuselage.
The first flight of a new model of the An-14 was produced in April 1968 years. A further development was the new aircraft, which had a relatively short takeoff and landing, the model was called An-28. It was equipped with a more powerful powerplant 2 × 940 hp Designer of the new aircraft was appointed Dmitry Kiva.
The aircraft was designed to carry out landing on unprepared sites, so the designers have abandoned the option that the chassis will get out of the fuselage. Nishi, where would be the chassis, were constantly clogged with dirt, and this would lead to failure. A prototype of the new passenger aircraft An-28 29.02.75 year for the first time looked, and the first flight took place on pre-production models in 1975 year. In the same year began full-scale tests.
This machine was tested in all climatic zones of the Arctic and to Antarctica. Serial production of aircraft began in 1984, in Poland, and in the next year, this model has received a certificate from GOSAVIAREGISTR USSR, which confirmed the airworthiness of the machine and at the same time met all international requirements and standards.
Characteristics of the aircraft AN-28
An-28 constructed under the scheme with vysokoplana braced type. This gives the aircraft a good aerodynamic properties. Due to the fact that the chassis is retracted into the fuselage of the aircraft loses little speed and aerodynamics. In this model, the aircraft is possible to install floats instead of the standard chassis.
The aircraft has dvuhkilevoe plumage. The power unit is composed of two models of engines theater-10 and equipped with reversible screws. Interior of the airplane can be easily changed for a variety of transportation. This model can be used both passenger and freight embodiment, moreover, as an administrative vessel.
An ordinary-28 can be quickly and easily converted into a plane for transportation of goods, it needs to be folded passenger seats, which will put the goods. For a more convenient and fast loading aircraft is equipped with cargo door, which is located in the tail of the plane. The cargo compartment of the aircraft is equipped with a crane, which can facilitate and speed up the loading process. This mechanism is able to lift loads weighing up to half a ton.
In the design of the airplane, much attention was paid to measures that ensure the safety of the flight in any, even emergency. Flying at a high angle result in a loss of speed, but the plane will not pass the buck, and is stabilized by an automatic system crafted slats. In this situation, the aircraft will automatically begin to lower the front part and recover airspeed while maintaining excellent handling.
The Antonov Design Bureau was first developed and installed on the aircraft An-28 system that could reduce their own bank machines in flight. This system allows you to safely and easily manage the data plane even with one working engine. She has a patent which is registered in France and the United States. Empennage thought so effectively that allows pilots to easily manage aircraft An-28 even at low speeds.
Aircraft model AN-28 able to make flights at different weather conditions and in all climatic zones, regardless of the time of day. All this is possible due to the fixed onboard navigation system and a system which prevents icing of the aircraft body and its functional parts.
Serial production of aircraft of this brand went up to 1997 years. Total production units were manufactured 198-28 An aircraft and its modifications.
Commercial use of An-28
Long experience has shown many of the airlines that transport over short distances need more quality aircraft-terrain vehicle, which must perform various tasks. Such a machine and began manufacturing aircraft Antonov Design Bureau. And, indeed, this car transports passengers, cargo and manufactures military rescue operations. It is used by scientists to geological investigations and for aerial photography. This all shows that the new model was the multifunctional and yet easy to operate and stable in flight.
For a more profitable use of the aircraft is equipped with a powerful enough, but the economic engines of the new generation. It should be noted that in the construction of aircraft designers spent a lot of time and bring a lot of design ideas. All creation of small and light An-28 take as much force as was spent in the design of a large AN-22.
The main advantage of this machine is that it is able to land and take off from unpaved surfaces up to 600 meters. He is able to do in the way of 600 kilometers at a high enough cruising speed in 350 km / h. In addition to these all advantages, it is much more economical than its predecessor AN-2.
Smaller airports that do not have concrete pavement can not take aircraft with retractable landing gear throughout the year, because it can lead to a crash. Sodden ground airfield will score a niche to enter the chassis. It was on such flights and benefit from An-28. This machine is not afraid of changes in temperature and air, which makes it suitable for transport in all weather conditions, even the harshest.
Aircraft Modifications An-28
The standard model of the aircraft is a cargo-passenger, it can be converted from one type to another. For more severe conditions the aircraft was established with a large reserve of fuel. To overcome the large distances, this modification is called An-28A. The main area of use is the polar latitudes. There are military versions of the aircraft, they are used mainly for paratroopers landing on enemy territory. A model called the An-28RM, which is designed for patrol and rescue operations. The most powerful version is the An-28 with the additional name of "Srayker", it is equipped with two motors in 1100 horsepower each. In this working screws are not three but five blades.
Statistics show that during the whole period of operation until September 2012 years lost only 25 machines model of the An-28.
Antonov An-28, a lightweight multi-purpose, twin-engine aircraft with short takeoff and landing. The main purpose of the aircraft is to transport people to the local air directions, cargo transportation, geological surveys, fire patrol, casualty evacuation, search and rescue, and intelligence operations. An-28 designed to carry people to the 18 1500 at an average distance of kilometers.
The aircraft has an all-metal fuselage with a high-wing, which is a two-spar construction, reinforced with metal struts. The wing has a large scale and is equipped with automatic flap that allows the aircraft to keep a stable flight at low speeds and high angles of attack and provides takeoff and landing at a steep angle of trajectory. Under the wings of the aircraft, gondolas, placed gas turbine engines, turboprop 10B. The passenger cabin can be easily converted into the cargo bay.
An-28 was designed by Antonov Design Bureau, based on a multi-purpose, light aircraft An14, which was in turn built 1958 year. And so the project initially received the designation of the aircraft An-14M. When saving circuit twin-engine monoplane, the new aircraft, compared to its predecessor, it was a lengthened fuselage. Also on the plane for a seat piston engines were installed turboprop engines GTD-550SA power 640 hp ..
The first test flight of the prototype An-14M held 30 April 1968 years. But the beginning of the flight tests of the aircraft was delayed until 1972 years. With the start of flight tests on aircraft engines were installed theater-850 810 maximum power hp .. Since then, the AN-14M received a new designation - the An-28. The first flight of the aircraft, already as the An-28, held January 29 1973 years. Later, aircraft engines have been replaced by the HPT-10B motors, power 960 hp .. Flying with these engines, pre-production aircraft An-28 1975 made in April of the year. After passing the state tests in 1986 year, the aircraft was put into production. But after the release of several production aircraft AN-28, 1987 in the year, manufacturing license was transferred to the Polish aircraft factory PZL Mielec.
An 28 Salon
Polish first An-28 took to the skies in July 22 1984 years. Later in 1992, the aircraft was modified and was designated PZL M28 «Skytruck». In this modification of the aircraft installed efficient engines Pratt & Whitney PT6A-65B, Canadian production capacity of about 1100 hp .. also equipped aircraft PZL M28 new avionics «Bendix-King». The release of this modification of the aircraft began to 1993 years and made to date on the Polish aircraft factory in Mielec.
