There are many things that catch our attention when we get on a plane. For example, why can’t we feel the speed, why are we cold, why do we feel sleepy?
We will leave the answers to all of these until last. Our topic today is why the windows on the plane are oval rather than square or rectangular.
As the plane rises, atmospheric pressure decreases.
As you know, planes go to high altitudes. The reason for this is to reduce friction and turbulence. Of course, as these are reduced, atmospheric pressure also decreases.
For a safe flight, the pressure inside the plane needs to be adjusted because as the plane rises, the pressure inside and outside the cabin differs.
Pressure must be distributed evenly throughout the aircraft.
Let’s distribute the pressure evenly, but at this point a problem arises: the windows. Because of the windows on the plane, the pressure moves sideways.
In addition, the force per unit area on sharp corners increases exponentially. You can examine the tension in the corners from the image. Sharp corners are structural weak points.
Now let’s look at airplane windows. corners are oval; It allows air pressure to spread in circular curves over the entire surface, thus increasing safety. In addition, the possibility of breakage that may occur due to the sharpness of the corner is prevented.
For all these reasons we mentioned, airplane windows are designed as oval rather than angular.
