The Boeing 787 Dreamliner is a long-range, mid-size wide-body, twin-engine jet airliner developed by Boeing Commercial Airplanes. Here are some key aspects:
Development and Design
- Launched in 2003 as a response to the growing demand for more fuel-efficient aircraft, the 787 was designed with advanced technology to reduce fuel consumption and emissions.
- It features a composite airframe, which significantly reduces weight compared to traditional aluminum airframes. This design contributes to better fuel efficiency.
- The Dreamliner uses electrical systems rather than pneumatic, which further enhances efficiency and reduces maintenance needs.
Key Features
- Fuel Efficiency: Up to 20% less fuel burn than similar-sized aircraft.
- Range: Depending on the variant, ranges from 7,000 to 8,555 nautical miles.
- Passenger Capacity: Variants can carry between 242 and 330 passengers in a typical three-class configuration.
- Technology: Includes the GEnx or Rolls-Royce Trent 1000 engines, advanced avionics, and electronic flight bag systems.
History
- The first 787 rolled out of the factory on July 8, 2007, but faced numerous delays due to issues with assembly, suppliers, and certification.
- Its first flight occurred on December 15, 2009, and it was certified by the FAA in August 2011.
- The initial delivery was made to All Nippon Airways (ANA) on September 25, 2011.
- Production has been affected by various challenges including battery issues, which led to a grounding of the entire fleet in 2013.
Variants
- 787-8: The original variant, with a range of approximately 7,355 nautical miles.
- 787-9: A stretched version introduced in 2013, increasing range and seating capacity.
- 787-10: The longest variant, first delivered in 2018, with reduced range but increased capacity.
Operational Impact
- The Dreamliner has opened up new routes due to its long range and efficiency, allowing airlines to fly non-stop between cities that were previously not economically viable.
- It has also influenced competition, with Airbus responding with their A350 series.
