Boeing 787 - Less Weight with More Efficiency


First in 12 years: Boeing's new creation - 787 Dreamliner - an ultra-light jetliner made of carbon-composites, making it more environmental friendly and more fuel-efficient.

The new plane was unveiled on Sunday in Everett, Washington State, US with about 15,000 employees, company's customers and suppliers present at the ceremony. This was the first time a Boeing 787 Dreamliner made its appearance before the crowd.

The first look at this jetliner would not offer you a lot of details that make it very different from earlier models of Boeing, yet the company assures that it is a completely new model. Here's some specs: 50% of the structure is made of carbon-composites, 15% titanium, 20% aluminum, 10% steel and 5% of other materials. This makes the plane extremely lightweight and more efficient than the existing planes of the same size. In addition, according to the company, Boeing 787 consumes 20% less fuel and produce 20% less greenhouse gas emissions.

Boeing also says that the air in the cabin will be more humid and thanks to more fatigue-resistant and rust-free composites used in the plane, passengers will benefit from a more pleasant flight.

Boeing didn't hesitate to use modern technologies when designing the plane's interior. At the beginning of 2007 the engineers introduced wireless technologies in the plans to build a modern entertainment system inside the aircraft, thus getting closer to 'losing weight' due to less cables used inside the plane.

Previously the Dreamliner was not 100% ready for the first flight. According to Boeing, the 787 could not take off for some time due to the fact that some modifications had to be made. As soon as the company presented its new plane, it started working on the improvements.

It would be interesting to note that after presenting the Boeing 787, the comapny managed to obtain over 30 proposals for more than 650 airplanes. This figure could lead to a revenue of at least $100 billion.

The first flight of the Boeing 787 was planned for August-September 2007 but it was delayed until a later date. In September of 2011 All Nippon Airways became the first company to try the new airplane with the first passenger flight expected to be performed from Narita, near Tokyo, to Hong Kong in Oct. 26. It is worth mentioning that depending on the version of the jet, the cost of each plane ranges between $185 million and $218 million (from 210 to 290 passengers will be able to travel on a single Boeing 787).
