The Evolutionary Changes in Construction Between the De Havilland Essay

The Evolutionary Changes in Construction Between the De Havilland Comet and the Airbus A380 Aircraft - Essay Example In addition, the jetliner also had a large square window and a pressurized fuselage. Regarding the era, the Comets provided a comfortable passenger cabin. It made its first commercial debut in 1952 where it flew without any problem. Its successful debut as a commercial jet helped drew passengers from all parts of the country with an interest in using the Comets as their preferred choice of flight. However, the success stories of the Comets did not last long since the airplane began experiencing problems just a year after its commercial service debut. In fact, three of the Comets broke up while, on flight resulting in an accident, that received wide publication by the media, according to Montagu-Pollock (2012). Investigations that followed showed that the accidents occurred due to catastrophic metal fatigue that the manufacturing engineers did not understand property at the time of its manufacturing. This prompted the withdrawal of the Comet from service after which it was taken for e xtensive testing to unearth the real cause of the accident. Investigations showed that the accident had initially been wrongly blamed on poor weather. Instead, design flaws were identified, which included dangerous installation methodology, and dangerous stresses at the corners of the windows. As a result, the Comet was modified with oval windows and structural reinforcements among many other changes, notes Nolan (2010). The other rival manufacturers of aircrafts learnt from the Comet and began making improvements in their while manufacturing processes avoid the mistakes made during the manufacture of the first Comet. Overview of the construction design of the Comet The first De Havilland Comet was made entirely of metal low-wing cantilever monoplane, observed Montagu-Pollock (2012). They had four engines, two of which were mounted below the wings for powering the plane. The two engines were buried under the wings to prevent the drag of podded engines, as well as to give room for sm aller fin and rudder. The mounting of the engines higher in the wings was also meant to reduce the risk of injection damage, which had been a major problem associated with turbine engines. It also had four-place cockpits for two pilots, navigator, and a flight engineer (Nolan 2010). Unlike the features of the aircrafts of the time, the first Comet had a clean low-drag design, which included the swept-wing leading edge, four-wheel bogies, and integral wing fuel tanks. The original De Havilland Comet measured almost the same length as the later Boeing 737-100. However, it carried fewer people in a spacious environment than the Boeing 737-100 (Birtles 1990, p.11). The British Overseas Airways Corporation (BOAC) installed 36 reclining ‘slumber seats’ with center measuring about 45-inches allowing for a greater leg space both behind and in front. Air France, on the other hand, was fitted with 11 rows of seats plus four seats installed on its comets. The plane also had tables where passengers can have the feeling of enjoyment and comfort. Amenities included a large galley capable of serving hot and cold cuisines and drinks, according to Ron and Patterson (2010, p.19). It also had toilets for both men and women. Because of the safety concerns, the airplane had an emergency section, which included several life rafts kept in the wings, just next to the engines. However, after encountering problems while, on flight, several improvements have been made to ensure that such accidents do not occur
