Why are the Boeing 787 Dreamliner Windows so much larger?


The windows of the Boeing 787 Dreamliner are fantastic. You can electronically dim the light in five different levels of sunlight and visibility. So it is much better than the typical airplane window, with the shutter shade options or full light entry lock. But the coolest thing about the Dreamliner windows is how big they are. Why can the 787 get bigger windows, but the other planes do not?

What is so different in Boeing 787 Dreamliner?

The Boeing 787 Dreamliner is largely made of plastic strengthened with carbon fiber.

The Aeronautical Engineering behind this explains that the composite material that comprises most of the Boeing 787 Dreamliner can endure more voltage than the traditional aluminum used in an aircraft fuselage. And this is important because the windows block the flow of tension in the structure, and too much stress could lead to cracks, which, as you can imagine, are not suitable for airplanes.

Aircraft windows, therefore, are oval because the pressure flows better around oval windows than squares (where things can be piled up). Aircraft windows are also small because larger windows end up over-tightening the tension. The Dreamliner can have larger windows because its composite materials are more suitable for handling pressure than metal. Therefore common planes their windows are so small.

However, for a deeper dive into the differences between the two types, see the video below, in English, made by Royal Engineering.
