Antonov An-225 Mriya The Biggest Airplane
Posted by bensto in AIRPLANE on 02 27th, 2008Currently the world’s largest aircraft, the An-225 Mriya (dream) stemmed from the need to transport large items for the Soviet space programme. 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 centre section, thereby increasing the span while keeping the engine installations the same. An additional pair of D-36T turbofans is fitted to the new centre 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 centre section. These supports and other smaller ones along the fuselage top are faired over when notin use. Toavoid buffetingfrom the ‘piggyback’ load, the An-225 has twin vertical fins mounted on the end of a large tailplane. The prototype made its first flight on 21 December 1988, and in March 1989 setup no fewer than 106 world and class records in one flight from Kiev, at a maximum take-off weight in excess of 500000kg (1.100,000lb). Only two have been completed so far. and the first flew with Buran on 13 May 1989. This combination made a dramatic appearance in the West for the first time a month later at the Paris Air Salon.

The Aerion Supersonic Business Jet will be able to cruise at 1.15 Mach over land without producing in mass product.First unit has been purchased by Sheikh Rashid from Dubai UEA, with this price over $ 80.000.000 Aerion Supersonic become Luxurioust jet in the world. From Paris to New York, this metal bird in just over 4 hours.It’s mean at this speed the Aerion can cross the Atlantic in two hours (it has a 4,600 miles range over 45,400 pounds of fuel).The plane can also keep a 0.98 Mach speed offering a similar cost-per-mile than competing subsonic private jets and complying with US regulations.
