Science behind airplane windows: Have you ever thought while traveling in an airplane why their windows are always round or curved? Why not square or rectangular? It is not just a matter of design, but a very interesting and important scientific reason behind it, which is associated with the safety of travelers and the strength of the aircraft. Let’s know what is its science!
Atmosphere pressure game
When an airplane fly at a height of thousands of feet, the atmospheric pressure is very low. At the same time, inside the aircraft, the comfort of the passengers and pressure for breathing is kept as a pressure near the ground. Due to the difference of this large pressure, there is a lot of stress on the outer body of the aircraft.
Danger of square windows
In the early jet era, some aircraft had square windows. But soon a big problem came to light. The pressure on the corners of the square windows was very concentrated. Stress always increases on any pointed corner, causing a risk of cracks and weakening of the metal. In many painful accidents in the 1950s, there were cases of disintegration from the corners of the square windows of the aircraft. It was a serious security flaw.
Spherical windows: Amazing engineering
Scientists and engineers studied these accidents intensively and found that spherical or curved shapes distribute stress equally. When a window is round, the pressure on it spreads over the periphery rather than focusing at one point. This reduces the stress on the metal and almost eliminates the risk of window breakdown or damage to the structure of the aircraft.
Imagine a bloated balloon. If you put a direct cut on it, it will burst. But if you spread it slowly, it can better handle the pressure due to its round shape. Similarly, the circular windows of the airplane work.
Not just security, Rather strength is also the reason
Spinal windows are not only important for safety, but they also increase the overall structural integrity of the aircraft. This helps to maintain the torso of the aircraft a strong and safe unit, especially in the environment with extremely pressure.
