An-8, which NATO codification was called "Camp" - a Soviet military transport aircraft development OKB. Antonov mid 50-ies. device purpose is to transport various cargoes affected, in desantirovanii parts VDV with equipment and weapons.
The development of the twin-engine aircraft An-8 engaged in OKB. Antonova at the beginning of the year 1954. Lead designer of the project was appointed A. Ya Belolipetskii. To carry out design works have attracted a number of specialists from other engineering offices. In April, the 1954 they were joined by a large group of graduates from the Kharkov Aviation Institute. Much of the credit for the construction of aircraft owned aircraft designer RL Bartini, which, in particular, belongs to the floor structure of the cargo compartment. The aircraft developed simultaneously in two versions: the passenger (the product "H") and military transport (the product "P").
Initially it was planned to equip the car engines TV 2F further involves the installation of engines 2T TV.
The development of a military transport variant progressed faster than the passenger, and soon the last project is completely frozen. Instead, he began to develop the An-10 (product "Y"). Work on the draft design of the transport aircraft were completed in July 1954 years. In the course of designing the designers decided to many complex problems that have been associated with the airlift of cargoes.
25.10.1954 before prototyping Commission were represented 2 aircraft layout options: the first was in the layout turboprops TV 2T second - turbojet AL-7. Then, at the Kiev aircraft plant began assembling the first prototype, which was completed at the end of the year 1955. The first rise in the air made the test pilots Ja Vernikov and VP Vasin with Svyatoshynsky airport (Kyiv).
The first public presentation of An experienced-8 before the general public was held on the air parade in Tushino with another novelty Soviet aircraft Tu-104. State tests of the aircraft took place in the autumn of the year 1956. They found insufficient indicators of static stability and controllability of the aircraft crosswind and landing, the occurrence of spontaneous self-oscillations in flight in a straight line, the lack of traction engines at high altitudes.
It was proposed instead of motors TV 2T use AI-20, but their power supply was clearly too small. At the suggestion of AG Ilienko AI-20 crossed and brought the power of each to 5180 hp In 1957 was carried out to complete the prototype aircraft engines AI-20D. Factory testing of the aircraft with the circuit layout ended November 21. Parallel to this, in the ASTC. Antonov aircraft design finalized: wingspan increased by 0,8 meters installed antispin spoilers and keel of the AN-10, strengthened fuselage.
For serial production of the AN-8 1957 started from the end of the year at the Tashkent aviation plant. The first production machine was released in August 1958 years. In the spring and summer of 1958 years were factory and state tests of production aircraft. In the same year it adopted a military transport aircraft USSR. At the Tashkent aircraft plant during the years of mass production (1958-1961) released 151 plane. It was in the service of BTA up to 1970 years. Until that time blamed 80 machines. And the remnants of redistributed between different state agencies, departments and ministries.
In 1997, in the fleet of Russian airlines were five AN-70, which operated in the Middle East. In 2004 year ASTC. Antonov has refused to take responsibility for the state of the apparatus AN-70, which have been exploited. But An-70 flights did not stop after that.
In accidents and disasters in the years of application were broken An 27-8.
An-8 is an all-metal cantilever high. The fuselage is made monocoque type, has a rectangular type cross section with sharp corners and in the middle of the rounded top. Dvuhlonzheronnoe wing, straight, trapezoidal. The wing is equipped with a double-slotted flaps and ailerons two sections. Chassis tricycle, has a bow-driven rack, retractable into the fuselage. Low pressure pneumatic chassis allow the aircraft to carry out takeoffs and landings on unpaved airfields.
The structure of the power plant consists of two turboprop engines AI-20, which were completed feathering AV 68D with four-screws. The left cowl chassis has a turbine TG-16. Control cabin sealed, partially armored. The cargo compartment is not sealed. Cargo hatch has dimensions 2950 × 740 mm and is located in the rear fuselage. Used self-propelled equipment carried by winch BL-52. Group dropping cargo can be carried out using a conveyor P95-T. Fuel is reserved in 20 soft wing tanks, the total capacity of which is 13 080 l.
Equipment and armament An-8
The structure Bomber weapons include bombs lighting: six TSOSAB-10 fixed on the holders at the tail of the fuselage, four FOTAB-100-80 - on tape in the bow. Cannon fodder equipment a tower with two guns caliber 23, tower-wire control system and sighting and computing unit.
The aircraft is equipped with cameras for day and night shooting.
Transportation and landing equipment can be placed inside the cargo cabin personnel with special equipment, their parachute landing, mounting equipment and cargo, and their discharge.
Handling self-propelled machinery run under its own power, using self-propelled ladders, which are carried on board. Dumb equipment immersed with electric winch or a tractor that is not part of the aircraft equipment.
