Porthole aircraft. View from the plane window. A photo.
Perhaps few people, even including those who are well acquainted with the history of aviation know porthole plane I not always had round pairing. The history of this is both interesting and tragic, but the resulting bitter experience ever brought to the fact that view from the airplane It will always be for us to have a rounded shape.
View from the airplane
The story of the round windows of the aircraft with which we are dealing with at the moment, begins with the appearance of one of the first civilian jet airliners, called "Comet". The plane appeared in 1954 year, and had some of the best specifications at the time, and during the races in the civil aviation, this was a very important factor, because the speed of air travel means more passenger traffic and, consequently, more profit. The clever design of the aircraft makes it very attractive, but a banal error led to the fact that the planes began to suffer the collapse one after the other in the air is literally falling apart into pieces. In just the first year of operation of the passenger liner was two plane crash, which killed 56 people, and the reason was quite obvious, but at the same time is incredible - square portholes.

Later identified as a special committee appointed to search for the causes of the crash of the "Comet" because of sharply converged square-shaped surfaces, porthole plane I am creating a kind of dangerous voltages which with increasing congestion and pressure almost instantly expands, thereby creating microcracks until, eventually, cracks do not reach a critical value and does not fall apart into small pieces plane. To find the cause of a long time it was not possible in view of the fact that when testing the aircraft in wind chambers were not used real overload, which counted only for the metal plating of aircraft. Only after 3 months after the last of the crash involving aircraft "Comet", experts have decided to subject the construction of aircraft overloading and excessive pressure, as a result, something happened that led in the past to the crash, which was so proud Aircraft Company "De Haviland." During full-scale tests, it was found that the high-speed flight, the cracks begin to appear just at the corners of the square windows, as a result, the corners are rounded, and the aircraft was subjected to new tests, which he successfully passed.
In this way, porthole plane performed rounded to:
- Withstand high overload and pressure;
- To provide the necessary aerodynamic properties;
- Germetizatsionnye provides better performance.
All these and other features allow the aircraft to have a better performance, both in terms of its reliability, both in terms of technical data.

Due to the fact that the causes of the crash of the "Comet" had been identified and corrected, all modern jet airliners used exclusively windows with rounded shapes, as a result, passengers can fly without worrying about their own lives. And now, once again, making airfare, you know why view from the window of an airplane It has a rounded shape.
