The 787-8 Dreamliner - a base model of 787 aircrafts family, is a new twinjet which was designed to meet the needs of airlines.
The airplane will provide nonstop services between mid-size cities having new levels of competence.
The customers will benefit of new services like: improved levels of comfort with larger windows, bigger baggage bins and innovation in the cabin environment, including higher humidity, cleaner air and lower cabin altitude.
The delivery of the first Boeing 787-8 is planned for the fourth quarter of 2010.
Since April 2004, fifty-seven customers around the world have ordered 866 of Boeing 787 aircrafts.
This thing makes the Dreamliner the fastest-selling new commercial jetliner in history.
The Boeing purpose related to the 787-8 to replace the 767-200ER and 767-300ER, as well as expand into new non-stop markets where larger planes would not be economically viable.
On December 8, 2009, in an unusual move, United Airlines announced an agreement for 25 Boeing 787-8s with an option for 50 more, while also ordering similar quantities of the larger Airbus A350.

Boeing 787-8 Dreamliner Exterior
The 787-8 Boeing the base model of the 787 family has a length of 186 feet (57 m) and a wingspan of 197 feet (60 m) and a range of 7,650 to 8,200 nautical miles (14,200 to 15,200 km) depending on seating configuration.
Dreamliner landing gear
Messier-Dowty of Velizy, France, has been selected to supply the main and nose landing gear.
The electric braking system provided by Goodrich and Messier-Bugatti, is comprised of the airplane wheels, electro-mechanically actuated carbon brakes and electro-mechanical actuator controllers.
The system offers advantages over hydraulic brakes of digital control and monitoring, reduced weight, high reliability. The absence of hydraulic brake fluid avoids the risk of leaks and possible fire hazards.

Boeing 787-8 Dreamliner Interior
"The 787-8 Dreamliner will accommodate 220 passengers in a three-class cabin configuration."
The 787-8 Dreamliner will carry 210 - 250 passengers on routes of 7,650 to 8,200 nautical miles (14,200 to 15,200 kilometers), while the 787-9 Dreamliner will carry 250 - 290 passengers on routes of 8,000 to 8,500 nautical miles (14,800 to 15,750 kilometers).
The airplane cabin offers a very comfortable environment with higher humidity, wider aisles and seats and larger (48cm×28cm) windows. The Boeing Interiors Responsibility Center oversaw development and suppliers for the 787 new concept interior.
The current configuration of the interior features repeated sweeping arches, dynamic lighting and electronic window shades whose transparency passengers can change during the flight.
Diehl Luftfahrt Elektronik will provide the cabin lighting, which will involve a ’simulated sky’ ceiling effect produced by arrays of light-emitting diodes (LEDs) which can change in color and brightness.
The 787 has larger centre-mounted overhead baggage bins that descend for easy loading and then pivot upward.

Boeing 787-8 Dreamliner Avionics
The Boeing 787-8 avionics are based on open systems architecture.
This will replace traditional dedicated signal wiring with remote data concentrators. The concentrators link effectors and sensors to a distributed computing resource through a dedicated communications network. This has an important contribution to the weight reduction.
Astronautics Corp. provided the dual electronic flight bag (EFB), which enclose all the documentation demanded by the pilot in digital format.
|Flight Controls||Digital fly-by-wire|
|Electrical||Variable-frequency electrical system powered by Hamilton Sundstrand power generators and APU|
|Hydraulics||5,000 psi (34,475 kPa)|
|Braking||Goodrich or Messier Bugatti electric brakes|
Boeing 787-8 Dreamliner Engines
The aircraft has some extremely quiet engines, being powered by high-bypass 10:1 ratio.
The fuel competence of the engines contributes up to 8% of the improved efficiency of the airplane.
These aircrafts could have two powerful engine types: the General Electric GENX and the Rolls-Royce Trent 1000, with a thrust of 55,000lb to 70,000lb.
“This is another exciting step in our progress on the 787 test program,” said Scott Fancher, vice president and general manager of the 787 Program, Boeing Commercial Airplanes. “Our partners at GE have worked diligently to ensure their engines are ready for the testing that is going to occur both before first flight of ZA005 and throughout the flight test program.”
Boeing engineers are proud about the initial results, which showed the GEnx performed just as expected.
"There is a lot of good, hard work happening to keep this program moving forward," said Scott Fancher, vice president and general manager of the 787 Program. "The team is following disciplined processes that have resulted in success with the first four airplanes."
Topspeed Speed 560 mph
Each 787 versions use the same engines models that fit to a standard engine interface permitting interchangeability.
Also in favor of electrical systems, have been eliminated the traditional bleed air heating and de-icing systems have been eliminated.
The General Electric GENX (GE next generation) engine is a derivative of the GE90 engine, using a high-pressure ration compressor, a composite fan blades and a single annular combustor where the compressed air and fuel are mixed, to provide very low level of emissions.
The Rolls-Royce Trent 1000 is a new ultra-high-thrust model of the Trent family, using a three-shaft layout.
Hamilton Sundstrand of Windsor Locks Connecticut supplies the primary power distribution system, auxiliary power unit, environmental control system, primary and remote power distribution system and the electrical power generating and start system.
|Powerplant||General Electric GEnx or Rolls-Royce Trent 1000|
|Engine Rating||2 x 64,000 lb (284.7 kN)|

Boeing plans to obtain the business and operations of Vought Airplane Industries at its South Carolina facility. The company makes fabrication and assembly of systems and structures installation of 787 aft fuselage sections.
