The Failure of the De Havilland Comet Aircraft

The failure of Comet de Habyland after World War II and the jet engine technology that appeared in most times know that aerospace engineers have great potential in the civil aviation industry. The comet was the first aircraft using jet propulsion equipment; however, the designer did not take into account the results of its heterogeneous window design under the metallurgy of aircraft materials or under flight conditions. The aircraft was designed by De Havilland Aircraft Company in the UK and ordered in May 1952.

The Jet IV aircraft traveled through Dehavirand and in 1949 it became the world's first comet of a jet airliner. It features four de Havilland ghost turbojets, aerodynamic clean design with pressurizers and large square windows. In this era, we offered relatively quiet and comfortable rooms and showed signs of commercial success when we first debuted in 1952. However, one year after coming into commercial service, the comet began to have a problem. Three of them collapsed in a famous accident happening in the middle of the flight. Later it was discovered that this is due to catastrophic metal fatigue of the fuselage, but it was not so obvious at the time. Iridium was tested extensively to terminate the service and find its reasons. At the same time, competitors' manufacturers listened to the lessons of comets while developing their own aircraft.

The UK will dominate the jet age. In 1952, de Havillands Comet launched commercial service and succeeded in connecting London to the most distant place of the empire. Jet aircraft has been superior to competitors over the years, looks gorgeous, and sets new standards for comfort and quietness in the air. Then something went wrong. The comet came down from the sky in 1953, the cause of the crash was bad weather and pilot's mistake ... In 1954 the second comet fell from the sky near Rome. The fleet was earthed for 2 months during the maintenance period. "There is no clear cause of the accident, but amendments have been made to cover all the possibilities of imagination leading to disasters.When these modifications are completed and the satisfactory flight test has been done, the Board of Directors Please resume your passenger service.
