Design and developmentEditThe An-72 first flew on 22 December 1977. Produced in tandem with the An-72, the Antonov An-74 variant adds the ability to operate in harsh weather conditions in polar regions. Other An-72 versions include the An-72S VIP transport and An-72P maritime patrol aircraft.
An unusual design feature of the An-72 and An-74 is the use of the Coandă effect to improve STOL performance, utilizing engine exhaust gases blown over the wing's upper surface to boost lift. The first flight was made in August 31, 1977, but it was only in the 1980s that production started. The power plant used is ZMKB Progress D36. The An-72 bears a resemblance to an earlier aircraft, the Boeing YC-14, which also used overwing engines and the Coandă effect.
The An-72 is often called cheburashka by Russians because with its large intake ducts located close to the fuselage, it resembles a popular animated creature in Russian cartoons.
Price for a new built An-74 in 2006 is quoted as being $17-20 million.Template:Fact
