The Boeing 787 Dreamliners, including its spacious design, seating arrangements, and the luxuriously comfortable take off and landing, is amazing. But the best thing about the airliner is its larger than average windows. Besides the cool electronic display, their sheer size is worth getting excited about.
Have you ever wondered how the Boeing can afford to make their windows big enough to look like vertical panoramas of the sky? The answer lies in their superior and material selection for the plane’s chassis.
Unlike most of the planes that are made of aluminum, Boeing 787 actually uses carbon reinforced plastic for their structure. Although this special plastic is a lot more expensive than aluminum; but provides better flexibility in design along with superior strength.
As YouTube’s channel Real Engineering explains, the composite material used in the Dreamliner is able to absorb more stress than the traditional aluminum fuselages. This feature is important as when a window is installed inside a plane’s frame, it blocks the flow of stress and creates stress concentration points which can lead to the creation of cracks in the structure.This Is Why The Windows Of Boeing 787 Dreamliner Are Larger Than Those Of Normal Airplanes
Airplane windows are made as small as possible to avoid disruption in the stress distribution which is why airplane windows are made oval rather than square or rectangles, as the stress flows much better when it doesn’t have to turn on sharp corners.
So the Dreamliner can afford bigger windows simply because the composite materials are better at absorbing the stress than the traditional metal structures.
