An-225 - heavy transport aircraft. It has made the first flight on December 21 1988, three weeks after after presentation. On March 22, 1989 An-225 has won 106 records during 3.5 hours of flight. An-225 was the first plane which is capable of rise of a payload more than 450 tons. The control surfaces of An-225 are controled by hydraulics inspected computer-controlled web by electronic servomotors. It makes a plane more sensitive.
An-225 is supplied with 6 turbines D-18T with a reversion of draft. The crew of a Currently the world's largest aircraft, the An-225 Mria (dream) stemmed from the need to transport large items for the Soviet space programme. Previously a converted Myasishchev Mya-4 'Bison' bomber had been used to carry outsize items on its back. but this had a limited payload capacity. meaning many components had to be disassembled or not carried at all.
Myasishchev VM-T was replaced by An-225 Mria as a transport for oversized, space program-related cargoes In mid-1985 Antonov was entrusted with the design of a new aircraft able to carry the Buran shuttle orbiter, large components of the Energiya launch vehicles and other outsize items for construction and mining industries. Construction of the An-124 provided the basis for the new aircraft, Antonov using many of the same components to keep cost and development effort down,
The fuselage and wings are similar to the An-124, the cabin retaining the same cross-sectional dimensions but with increased length. To save weight the rear loading ramp is removed, but the An-225 retains the nose visor. Standard An-124 wings are grafted on to a new center section, thereby increasing the span while keeping the engine installations the same. An additional pair of D-36T turbofans is fitted to the new center section. raising thrust to an amazing 1377 kN (309,540lb). In order to support the increased weight, seven pairs of wheels are fitted to each side as opposed to five in the An-124.
Outsize loads that cannot fit into the capacious cabin (including Buran and Energiya components) are carried 'piggyback', the load supported on two main attachments above the center section. These supports and other smaller ones along the fuselage top are faired over when not in use. To avoid buffeting from the 'piggyback' load, the An-225 has twin vertical fins mounted on the end of a large tailplane.
