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 |
