What types of aeronautical machines are described above?
Sukhoi Superjet 100 The Sukhoi Superjet 100 (Russian: Сухой Суперджет 100 ) is a modern fly-by-wire twin-engine regional jet with 8 (VIP) to 108 (all economy) passenger seats. With development initiated in 2000, the airliner was designed and spearheaded by Sukhoi, a division of the Russian civil aerospace company (UAC), in co-operation with several foreign partners. Its maiden flight was conducted on 19 May 2008. On 21 April 2011, the Superjet 100 undertook its first commercial passenger flight, on the Armavia route from Yerevan to Moscow.
Biplane A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a similar unbraced or cantilever monoplane wing. Improved structural techniques, better materials and the quest for greater speed made the biplane configuration obsolete for most purposes by the late 1930s.
