Aircraft Boeing

Boeing 787 Dreamliner is known for its twin engine, long-range, and mid-size, jet airliner developed by Boeing Commercial Airlines. The capacity of the new jet airplane is between 210 and 300 passengers. The capacity of the airplane is more dependent on the variant of Boring 787 Dreamliner. One of the main characteristics of the Boring 787 Dreamliner is its fuel efficiency as compared to the other Boeing jet airliners. As compared to 767, 30% lesser fuel is consumed by the new Boring 787 Dreamliner. Secondly, most of the materials used for the construction of Boring 787 Dreamliner include composite materials. Some of the main features of the new Boring 787 Dreamliner include windshield that is four paneled, engine nacelles that have the ability of noise reduction, and a nose contour that is much smoother (Carbaugh, 2010, p. 34).

Duration of 787 development

The development of the new Boeing 787 Dreamliner was based on an increased and a large-scale collaboration with global suppliers. The final assembly of the Boeing Dreamliner took place in Boeing Everett Factory in Washington. The assembly of the new jet airliner is also taking place in North Charleston in South Carolina. September 11 attacks slowed down the manufacturing of the jet airliners and more focus was on efficiency than on speed. Sonic Cruiser technology was not up to the mark thus it was cancelled in the year 2002. In 2003, it was announced by Boeing that the Sonic Cruiser technology will be replaced by the new 7E7 technology, later named as Dreamliner. In 2004, Japanese airline Nippon Airlines became the first customer of 787 Dreamliner. In 2007, the pricing of U.S.$200 million was set by Boeing. It was set to be launched for customer companies in 2008 but due to many factors, the launch was delayed. Maiden flight testing of the 787 Dreamliner was conducted the December of 2009.

First Buyer and Price of 787

On the 25th of September, 2005, in Everett, Washington, the new Dreamliner was officially first delivered to the Japanese Airlines, Nippon Airlines. The final price of the new Dreamliner was set to be U.S.$200 million (Norris, Thomas, Wagner, and Smith, 2005, p. 49).

Design and technology

The construction of the new Dreamliner is composed of lightweight composite materials. The construction materials are composed of 50% composite materials, 15% titanium, 20% aluminum, and 10% steel-based metals. One of the most important changes that have been incorporated in the new Dreamliner is the new electrical architecture which is an innovative replacement of the bleed air and hydraulic power systems that include pumps and compressors. Hydraulics and pneumatics from some of the most important subsystems have been completely eliminated. Another important change is protection against ice formation on wings. The new and well equipped wings now have electro thermal heaters which have replaced the hot bleed air mechanism. Air quality is improved during turbulence because of the newer gust alleviation system.

One of the most advanced features that have been installed in the new Dreamliner includes LCD display. These displays are of an industrial level of GUI widget toolkit. All 787s are composed of almost 35 tons of carbon fiber reinforced plastic. The main reason based on which composite materials are that they have the lowest strength to weight ratio (Norris, and Wagner, 2009, p. 90).

There are two main engines being used in the 787. All engines use electrical bleedless systems thereby superheated currents have been eliminated that have been used usually for power supply for aircrafts. Superheated air conduits are used for deicing and several other functions. Quiet Technology Demonstrator 2 is one of the most important projects of Boeing in which several new technologies were developed in order to reduce noise of the engines. The air inlet has been redesigned in the new 787. These inlets have newer sound and noise absorbing materials that make the flight even more comfortable. Exhaust duct covers have been redesigned in a way that the rims are dipped in chevron so that there is a noise free mixing of air and exhaust. These are the developments that make the flight more comfortable as the interior and exterior are much noise free. Noise reducing technologies have been adopted by Boeing in order to make sure that no aircraft leaves the airport having sounds greater than 85 decibels. The interior of the 787 has the capacity of 235 passengers in the three class setup. Two class domestic setup can carry almost 240 passengers. Arrangement of the seats is highly economic. The width of the interior is almost 18 feet. The space is greater as compared to other passenger airlines.
