  • Why do airplane windows have rounded corners?

    Why do airplane windows have rounded corners?

    A common question related to aviation equipment is: “Why are the windows in the bulkheads of airplanes rounded?”

    When traveling by plane, I like to look out at the blue sky and sea through the lovely round windows in the cabin.

    But in addition to its own aesthetic effect, what is the special reason for the shape of the aircraft windows are rounded?

    In fact, this is because up to 70% of the cabin pressure inside an aircraft is concentrated in the four corners of these windows.

    The round window is designed so that the four corners can effectively decompose the pressure, and it is also stronger and more resistant to deformation. Avoid stress concentrations that can lead to cracks in the structure.

    Why are the windows of airplane (aircraft) oval?

    When traveling abroad and taking an airplane (aircraft), I often feel puzzled. Why are the cabin windows all small and oval in shape?

    In fact, the aircraft cabin windows in the early years did not limit the shape, but with the advancement of science, scientists found that with the improvement of flight ability, rectangular windows can no longer afford high-performance flight mode, and the pressure will be concentrated on the four corners of the rectangular windows. As long as the pressure accumulates to a certain value, it may break the aircraft and even cause an accident of disintegration in the air.

    The elliptical window has also been confirmed by scientists that this shape can best evenly share the internal and external pressure difference stress. Therefore, aircraft manufacturers in the industrial age will naturally develop aircraft designs that best meet the definition of safety to make flying safer. The cabin windows of modern aircraft are basically oval-shaped (unless a local tyrant spends a lot of money to use a fighter-grade glass structure, which is an exception to the situation where it is to be rectangular).
