Boeing 787

Boeing 787 Dreamliner 

The Boeing 787 Dreamliner is a long-haul, wide-body, twin-engine jet airliner developed by Boeing Commercial Airplanes. 

Introduced in 2011, the 787 is designed to be significantly more fuel-efficient than older aircraft models, featuring advanced materials, cutting-edge aerodynamics, and next-generation engines.

The first 787 entered commercial service with All Nippon Airways (ANA) on 26 October 2011.


Key Features and Innovations

1. Composite Materials

  • The Boeing 787 is the first major commercial aircraft to use over 50% composite materials (mainly carbon-fiber reinforced plastic) in its airframe and wings.

  • This lightweight structure allows for 20–25% improved fuel efficiency compared to similar-sized aircraft like the Boeing 767.

2. Engine Technology

  • Powered by Rolls-Royce Trent 1000 or General Electric GEnx engines.

  • These engines are quieter and produce significantly lower CO₂ emissions.

  • Advanced nacelle design and serrated engine edges reduce noise during takeoff and landing.

3. Passenger Comfort

  • Larger, electrochromic dimmable windows (up to 65% larger than typical airliner windows).

  • Higher cabin pressure (equivalent to 6,000 ft altitude) and higher humidity levels, reducing passenger fatigue on long flights.

  • Wider cabins, improved air filtration, and LED lighting create a modern and comfortable flying experience.

4. Advanced Aerodynamics

  • Unique wing design with raked wingtips improves fuel efficiency and reduces drag.

  • Fly-by-wire controls for better handling and safety.



Variants of the Boeing 787

  1. 787-8

    • The smallest variant, seating 242 passengers (typical 3-class layout).

    • Range: 13,530 km (7,305 nmi).

  2. 787-9

    • Stretched version, seating 290–300 passengers.

    • Range: 14,140 km (7,530 nmi).

    • First delivered to Air New Zealand in 2014.

  3. 787-10

    • The largest variant, seating 330–340 passengers.

    • Range: 11,910 km (6,430 nmi).

    • Optimized for medium- and long-haul routes.



Performance and Range

  • Cruising Speed: Mach 0.85 (~913 km/h).

  • Fuel Efficiency: 20% lower fuel burn than previous-generation aircraft like Boeing 767.

  • MTOW: Up to 254,000 kg (560,000 lb) for the 787-9.



Operational History

  • The 787 has become a popular choice for long-haul flights, particularly for point-to-point routes, bypassing traditional hub airports.

  • It is operated by airlines such as ANA, Qatar Airways, Singapore Airlines, British Airways, United Airlines, and American Airlines.

  • Over 1,100 Boeing 787s have been delivered as of 2024, making it one of Boeing’s most successful wide-body programs.



Technological Innovations

  • Electric Systems: The 787 replaces many traditional hydraulic systems with electric systems, reducing weight and maintenance.

  • Advanced Flight Deck: Features large LCD displays, dual head-up displays (HUD), and electronic flight bag integration.

  • Noise Reduction: One of the quietest long-haul jets in its class.

Boeing 787 vs. Airbus A350

  • Efficiency: Both are highly efficient, but the A350 has slightly larger capacity and range (especially the A350-1000).

  • Cabin Comfort: Both offer quiet, modern cabins with high humidity and LED lighting, but the 787’s larger windows are a standout feature.

  • Market Focus: The 787 focuses on medium to long-haul point-to-point routes, whereas the A350 often serves ultra-long-haul, high-capacity routes.
