We tell you in this installment thaté and whyé There is a mysterious hole in the windows of commercial airplanes, where your safety is its main objective.
You board your planeón, you chose to sit by the window, you settle in your position, you look outside like a good AvGeek to see the movement of the Airport and suddenly… You realize that there is a littleñor and unknown gap, office, hole, aperture o perforationón in the lower center part of the window and you are left with this face ?.
I am sure that máDid you once ask yourself this or not?ñor curious, you asked your parents without a reliable answer, Well today we tell you the origin and functionón so smallñO, but mysterious orifice.
Aircraft window holes
First, we will talk hereí of its functionón on commercial airplanes, but these tooécan not be found on other large aircraft, little oneños, private, cargo or other, so they are not exclusive to Aerolídenies.
cleared this up, let's get to the point or let's go to the hole. This little oneñor space that we have seen in all the windows of commercial airplanes have a purpose and propóvery clear location, safety.
As we well know and have seen in other deliveries, airplanes are mámachines that in commercial passenger use, almost always, they are pressurized. As we well know or at least the lólogic tells us, for an aircraft to stay, pressurized, no gaps can exist in the fuselage of the aircraft, opposite case, it won't be possibleíto maintain the pressureón, but then ¿thaté makes that tiny hole?
These holes técynically they are called in English as 'bleed holes'.’ or 'bleed holes’ In spañol, but first it is necessary to indicate that the window through which we enjoy the exterior landscape, Eastá Composed of three panels, two of them made of acrylicílol, where the first is where we see the finger grease marks of hundreds of passengers and general dirt, the environment where it isá the «bleed hole» and the third which is the exterior that isá in direct contact with the environment.
the bleeding hole, allows theí balance the pressureón between the cabin and the space between the panels, of which the middle and outer ones do the task of maintaining the pressureón inside the grandfatherón. It is a pressure reducing orificeón in the center panel, so only the outer panel supports all pressure forceócabin number, and experience the pressure changesón gradually during the flight.
In the event that the exterior panel suffers damageños, the one in the middle will maintainíI took itón in the cabin, therefore ensuring your safety in the different stages of the flight, something so smallñO, is critical to the safety of aircraft occupants.
Finally, Another function of this hole is to release moisture and minimize frost or condensation.ón that blocks us from taking beautiful photos from the avión, That is why sometimes we can see cícircles of ice around this.
