Boeing :: essays research papers
                                                                                                         Paper on video â€Å"21st century jet†                                             In this paper, I would like to discuss on the video, â€Å"21st century jet.†This video is about the launching and testing of the airplane by the Boeing company, 777.The 777 family is designed to fill the size gap between the 767 and 747.The head of the 777 project is Allen Millaley, who promised to do many things which are impossible, produced the plane which is more reliable than any other plane in the aviation history. The first large passenger jet designed completely by computer, the 777 is more complex and innovative than any other airliner ever built. The important thing in this project was, at the peak of the design effort, there were 238 teams using computing technology to design the 777.Design engineers and manufacturing engineers worked concurrently on the design of parts to decrease later change orders and to increase efficiency in building and installing those parts. Outside suppliers and airline customers also are represented on some teams. According to one of the supervisor of a team, the traditional way of bringing problem is testing and more testing. Boeing 777 is the most tested airplane in the aviation history. Operations of flight controls, the reliability of electronics, all of these things tested and retested by the teams of engineers. Boeing has built new laboratory for 777 in which 10000 workers worked. The engineers did the first ground test of 777 in Nov’93. During the first testing flight only the pilot and co pilot were on board. The problem occurred during the first test flight was the hydraulic leakag e on the left side. After the first flight, several meetings held in which engineers tried to figure out the problem they had during the first test flight. After that the engineers made the successful testing flight. The Boeing 777-300, earned type certification from the U.S. Federal Aviation Administration (FAA) and the European Joint Aviation Authorities (JAA), on May 4, 1998. The jet also received FAA approval for 180-minute extended-range, twin-engine operations (ETOPS). This marks the first time any airplane manufacturer has received both approvals on the same day. The certification formally recognizes that the 777-300 has successfully passed all of the stringent testing and safety requirements of the regulatory agencies and is ready to enter passenger service.
