What happens to passengers when the airplane doors open in the middle of a flight?

byskeeze

The airplane in the flight is totally in a closed room and there is no escape place even if something happens, so there are a lot of people who imagine a sinister imagination. What happens to the passenger when the "door" of such an airplane opens during the flight? How does one get dead? To the question of scientific YouTube channelAsapSCIENCEI answer.

What If Your Airplane Door Burst Open Mid-Flight? - YouTube


Even if the civilian aircraft we use fly over 30,000 to 45,000 feet (9100 to 13,000 meters), the pressure inside the cabin is 8,000 to 10,000 feet (about 2400 to 3000 meters) offshore, It is adjusted to be about the same.


As the altitude of the aircraft rises, the ambient pressure decreases.


This is because the gravity on the molecule in the atmosphere is different. The closer you are to the ground the stronger the force that works on the molecule.


If the door of the airplane is opened by any chance the inside of the aircraft will be depressurized in less than 0.5 seconds and people and things will be discharged out of the airplane instantly from the air pressure unless you wear a seat belt.


In this case, the airplane itself may be destroyed, the probability of survival is extremely low.


In high-altitude places, the air is thin, that is, the amount of oxygen is small, so if the inside pressure decreases, the oxygen mask will fall from above.


But,Oxygen deficiencyThere is only an average time of 18 seconds to fit the oxygen mask before it happens.


Oxygen deficiency is a symptom that occurs when the oxygen level declines, causing nausea, dizziness, and awareness, leading to death.


The amount of oxygen supplied by the oxygen mask is the amount that allows passengers to survive for 10 minutes, during which time the pilot needs to lower the plane to about 2400 to 3000 meters in altitude. By lowering the altitude so far, the air pressure inside the machine and outside the machine will be the same, so it will be possible to prevent such situations.


Although it may have become uneasy to hear the story so far, in fact, the probability of opening an airplane door is extremely low. The air pressure is applied at 8 to 10 pounds (about 3.6 to 4.5 kg) per square inch (6.45 square centimeters) ... ...


The pressure applied from the inside is larger than from the outside.


Airbus A380The main door of the airplane is 2.8 square meters, and to start opening the door, 38,592 pounds (about 17,500 kg) is required.


This is comparable to the ability to move three African elephants.


And the opening and closing of the door is controlled from the cockpit, and only the pilot can operate.


Also, maybe you are worried about "If the window is broken?", The windows of the airplane are made by stacking high-strength polymer materials on six layers, and someone cracked by punching, bullets It will not happen that it will be destroyed by.


Moreover, by curving the shape of the corner of the window, it reduces the drag during the flight, making the window hard to crack.


As a matter of fact, the probability of a person accidentally falling into an accident during driving is 1/114, but the probability of accidents during a flight is much smaller than 1 in 9821. If you watch the safety movie by tightening the seatbelt, you can relax and enjoy the flight.
