Antonov An-180 is a medium-range airliner, which was developed in the design bureau DC Antonova. This wide-device was designed for the average number of passenger seats.
History of the AN-180
Designers Antonov Design Bureau began developing the project in An-180 1992 year. The first study included the installation of two engines, and the design features have decided to adopt in vysokoplana AN-70. But this idea was not realized due to the awareness that this construction is economically unprofitable.
Originally designed as a machine with a T-tail, but in the future, this scheme has been changed to a biplane tail. This increased the value of the vector aerodynamic stabilizer forces. Despite the merits of the aircraft had a major flaw, namely, it was the weight. In the end, the first machine was supposed to go in 95 year and serial production with 97-year.
Features An-180 constructions
An-180 manufactured cantilever scheme nizkoplan. The housing has a semi-monocoque structure with circular cross-section. Have a small swept wings, are installed at the ends of the airfoils. The total weight of the AN-180 42,5 ton structure was, and still he could raise the commercial weight 18 tons.
The cruising speed of the aircraft was 800 km / h at an altitude of 10 kilometers. The practical range with the passengers was 6,3 thousand kilometers. chassis system consists of three pillars, which are equipped with systems of amortization and brakes. To control aircraft took only two pilots. An-180 can be equipped with passenger compartment of two types, namely, the 163 and 175 passenger seats.
The power plant was presented with two engines D-27 propeller-type fan. They had a lot of power in 13,8 thousand horsepower each. Motors mounted on the ends of the stabilizer wings. An innovation in the aircraft design is that the engines were attached to the sides of the tail section. In addition, the new structure was and all the aerodynamic wing surfaces. The tail section was fitted with a T-shaped plumage structure. For all calculations, designers and analysts machine must be very economical.
From this project abandoned due to lack of funding by the decay of the Union. In addition, the aircraft has become less relevant in terms of reduction of excitement on air transport. In 2007, the Deputy Chief Designer of Antonov Design Bureau announced the final freeze development project An-180.
Despite the fact that the machine has not been established, the aircraft AN-180 project remains relevant today. Especially now that it can be fitted with more efficient equipment.
