Why are airplane windows round?

Why are airplane windows round?

When everyone goes out to play on the plane

I always prefer a window seat.

We always look through the window

The rolling sea of ​​clouds and the blue sky outside the window

However, few people noticed

These portholes on the plane (small windows on the plane)

Why is it designed to be round?

Is this by design?

In fact, the windows are designed to be round.

An engineering innovation that can save lives

If the windows of a commercial aircraft

Designed to be square like your windows

Then during the flight

The entire plane may face the tragedy of disintegration and crash.

Why aren't portholes designed to be square?

In the 1950s

Three planes broke apart and crashed

But these spate of accidents are no coincidence.

It's because engineers ignored

A critical design flaw

They used square windows

Square windows

It makes it difficult for aircraft to fly at high altitudes

Because of the atmospheric pressure and the

Slightly different pressure

This pressure difference causes the cabin to expand slightly.

At this time, the fuselage material - the window frame will be under pressure

The pressure difference becomes greater as the plane rises.

If it is a rectangular window

Pressure builds up on sharp corners

Causes glass to break and fuselage to crack

If it is an oval window

This allows the pressure to flow more smoothly

Avoid the entire process

The accumulation of potentially destructive pressures
