Designs of A380

Report on Designs of Airbus A380 Airbus A380 is commonly known as the jumbo aircraft as its capacity is up to 850 persons which weight almost 560 tons. As the maximum length of wingspan which is internationally recognize and can accommodate in most international airport is 80m, so A380 need to gain maximum lift with a length limit of only 80m. In order to overcome this limitation, the engineers observed the wings of eagle for some time and they found out that the end of the wing is folded slightly upwards. Next, they made out a prototype with a winglet on the end of the wing and placed it in a wind tunnel. They found out that the winglets of the wing can reduce the wing tip vortices which act as a drag that reduce the life force. This winglets design successfully overcome the limitation of short wingspan which cannot support such a heavy weight by reducing the drag and increase the lift.
As for the outer skin, the design must be as light as possible in order to reduce the weight and then gradually increase the lift. But then, the material used must not be too fragile as it has to withstand high pressure and impact from foreign objects such as birds. The main material used is a type of stainless steel metal, which is aluminium. But then, in order to withstand a high pressure the aluminium layer must be very thick and thus the weight is increased. So, the engineers got their idea from the short bow invented by Genghis Khan which wrapped the inner part with a layer of elastic fiber. Then, they tried to make a composite material by combining a layer of super light and super strong glass fiber. The glass fiber is made by burning glass with extremely high temperature which is about 15000 degree Celsius. This layer of glass fiber provides elasticity and strength on the other hand the aluminium layer provides stiffness. This type of specifically made composite material is 25 percent lighter than pure aluminium and thus the weight force is reduced.
