Why are plane windows round or oval in shape?

Have you ever wondered why plane windows are always round or oval in shape?

If you have ever flown, you must have seen it always and on all planes the windows are round or oval. But have you ever wondered why this happens and whether windows are chosen based solely on aesthetic principles or engineering reasons?

Why are aircraft windows circular or oval in shape and not square?

The plane window

Here we must say that the second option is correct, that is, aircraft windows are made circular or oval for engineering reasons necessary for the safety of the aircraft in the sky, and that this type of design is not at all coincidental and is chosen in a circular manner in order to increase the safety and health of passengers.

It is also worth noting that humans did not have this knowledge from the beginning, and that air vehicles had square windows in the past and in the 1950s, and after researching the crashes of these aircraft, they found that the reason was the shape of their windowsills. The windows were square.

The quadrangular window tires were subject to too much pressure and increased the likelihood of the windows being cracked and shattered. On the contrary, the roundness of the window frames helps to dissipate the pressure around them, so there is no tremendous air pressure on the windowsills in this way as they are slightly convex.

It's good to know that when an aircraft flies through the sky, the atmosphere's external pressure, turbo balance and traction decrease. The higher the height of the device, the greater the internal pressure of the cabin, which led to a noticeable difference in the pressure inside and outside the cabin, and this could lead to the opening of the fuselage if the windows were square, losing its balance and the occurrence of a dangerous situation that could lead to the crash of the plane.
