ORIGIN OF WINDOWS AIRPLANE FORM ROUND

If we tend to note, most traveller airplanes nowadays have a round window. Why is that?

Apparently, once this passenger plane has a box-shaped window. The plane named de Havilland Comet, or Comet 1 was used by British Overseas Airways Corporation (BOAC) in 1952, which was also the first commercial jet airliner. The design of the iron bird is referred to as a carrier of change.

At the time of the plane still using propellers, the British-made aircraft has been using four jet engines. The iron bird can fly higher than its competitors. The Comet plane also has a large box-shaped window.

Since its operation, Comet has transported millions of people. In the first year, the plane had transported 30 thousand people, including Queen Elizabeth. Not only became the first commercial jet, Comet also contributed to the aviation world with a number of tragedies that hit the plane.

The first incident occurred in 1954. The Comet de Havilland plane exploded in space just 15 minutes after take-off. The jet that departed from Rome to London and carrying 35 passengers and the crew, crashed in the Mediterranean Sea.

A few months later, another similar event occurred. As a result, 21 crew and passengers de Havilland Comet were killed on a flight from London to Johannesburg, South Africa. The plane crashed back into the Mediterranean Sea in the incident that occurred in 1954.

Reporting from News.com.au, Monday (20/3/2017), Comet jet accident that pushed the British Transport Minister to stop the flight of the type aircraft.

The bodies of the victims of the two events are showing a similar injury, skull fracture and rupture of the lungs. The accident investigation finally found the cause of the two aircraft crash. According to reports, metal fatigue that causes decompression and air separation are the cause of the incident.

Reported by the Telegraph, the box-shaped Comet window plays an important role in metal fatigue - a tendency for the metal to break when it receives repetitive stress - causing the jet crash.

The sharp angle of the window makes the metal around it experience extra pressure in the altitude, with the pressure two to three times larger than the aircraft in general. The concentrated voltage in the corner of the window causes the metal plane to become tired.

After an investigation, de Havilland finally made a number of changes to the design of the aircraft, including turning the window into a round. Thus, the voltage flows more evenly around the edges of the window. From there, all the aircraft up to now use a round window.
