Difficult and Glorious History of Boeing 747 Research Paper

sticky and Glorious History of Boeing 747 - Research Paper ExampleBoeing 747-100 Iran development of 747 occurred during the rapid growth of air commerce in the 60s. Boeing 707, which dominated at that age in the U.S. airline market, already struggling to cope with the change magnitude flow of stretch forthengers. Prior to that, the Boeing Corporation has worked to develop a large transport aircraft for the U.S. Army, but then lost(p) the draft Corporation Lockheed - C-5 Galaxy. Nevertheless, the most loyal Boeing customer - the airline Pan American - has developed requirements for the monstrosity passenger plane which was supposed to be more 707 twice. In 1966, the Corporation introduced a new human body of the aircraft, the designation 747. Initially, the project is a fully double-deck aircraft, but with this configuration, there were some difficulties, and the scheme was abandoned in favor of the hump. From the first series of 100 aircraft, Pan Am ordered 25. Hess, R. A., and Wells, S. R.At that time it was thought that such giants will soon be superseded by supersonic aircraft. Therefore, the 747 was originally developed as a transport aircraft. Over time, it was planned even a complete refurbishment of all aircraft into freighters. The cockpit was set on the upper deck specifically to be able to convert the nose of the plane in the cargo ramp. It was assumed that the market does not need more than 400 aircraft of this type, however, despite the criticism and spunk competition in 1993, was built thousand aircraft. Only in the first decade of XXI degree centigrade sales 747 began to fall. Construction of aircraft has been associated with some difficulties the Boeing plant did not have capabilities to produce such huge aircraft. To do this in a small town Everett, Washington had built a new factory, which became home to a new family of aircraft. Company Pratt & Whitney has developed a huge turbofan engine with a high pass ratio - JT9D, which was or iginally used exclusively for the 747. In order to improve safety and flying qualities of aircraft on the 747 were set back four hydraulic systems and slotted flaps, which are allowed to use the aircraft on the runways of standard length.
