The Dreamliner is 20% more fuel-efficient than the 767
The Boeing 787 Dreamliner is an American wide-body airliner developed and manufactured by Boeing Commercial Airplanes. It was launched on April 26, 2004, with an order for 50 aircraft from All Nippon Airways (ANA). The 787 was designed to be 20% more fuel-efficient than the 767. This was achieved through a variety of means, including the use of more fuel-efficient engines, aerodynamic improvements, and the increased use of lightweight composite materials.
The 787 Dreamliner's distinguishing features include mostly electrical flight systems, swept wingtips, and noise-reducing chevrons on its engine nacelles. It is powered by two new engines: the Rolls-Royce Trent 1000 and the General Electric GEnx. The use of these engines contributed to approximately 40% of the aircraft's overall efficiency gain.
The 787 Dreamliner is also constructed with composite materials as the primary material in its airframe, making it Boeing's most fuel-efficient airliner. This construction method reduces the weight of the aircraft, leading to improved fuel efficiency. The use of lightweight composite materials also improves the aircraft's aerodynamics, further reducing fuel consumption.
The 787 Dreamliner has a typical capacity of 242 to 335 passengers and a range of 7,305 to 8,500 nautical miles. It was designed to replace the Boeing 767-200ER and expand into new non-stop markets where larger planes would not be economically viable. The 787 has been well-received by airlines and has seen significant sales and deliveries since its introduction.

Boeing's most fuel-efficient airliner
Fuel efficiency is a key concern for airlines, as fuel costs can make up a large portion of operating expenses. The Boeing 787 Dreamliner is Boeing's most fuel-efficient airliner. It is a long-range, mid-size, wide-body, twin-engine jet airliner developed by Boeing Commercial Airplanes. The 787 Dreamliner was designed to be 20% more fuel-efficient than the Boeing 767, which it was intended to replace. It can carry 242 to 335 passengers in typical 3-class seating configurations and has a range of up to 7,635 nautical miles.
The high fuel efficiency of the 787 Dreamliner is achieved through the use of more fuel-efficient engines and lighter composite material airframes. The aircraft also features aerodynamic shapes, winglets, and advanced computer systems that optimise routes and aircraft loading. The use of composite materials as the primary material in the construction of its airframe also contributes to its efficiency. The 787 was the first production airliner to use one-piece composite barrel sections instead of multiple aluminium sheets and fasteners.
The development of the 787 Dreamliner was motivated by a desire to improve efficiency. In the late 1990s, Boeing considered replacement aircraft programs due to slowing sales of the 767 and 747-400. The 747X proposal aimed to improve efficiency by lengthening the 747-400, while the Sonic Cruiser would have achieved higher speeds while burning fuel at the same rate as the 767. However, the Sonic Cruiser project was dropped in favour of the more efficient 7E7, which later became the 787.
The 787 Dreamliner has been praised for its fuel efficiency, with Virgin Atlantic using a B787 to become the first commercial airliner to fly transatlantic on 100% SAF. Norwegian Air Shuttle, which operates the 787-8, was ranked as the most fuel-efficient airline, achieving 44 pax-km/L (2.27 L/100 km [104 mpg-US] per passenger). However, when compared to other super-economic options, the 787-8 falls short in terms of fuel efficiency.

The 787-8 is the only suitable replacement for the A300, A310, 767, and A330-200
The Boeing 787 Dreamliner is a long-range, mid-size, wide-body, twin-engine jet airliner. It is Boeing's most fuel-efficient airliner, designed to be 20% more fuel-efficient than the 767. The 787 Dreamliner's distinguishing features include mostly electrical flight systems, swept wingtips, and noise-reducing chevrons on its engine nacelles.
The 787 Dreamliner has a range of 7,565-8,500 nautical miles (14,010-15,700 km or 8,710-9,800 mi). The longest-range 787 variant can fly the Qantas QF 9 flight between Perth and London Heathrow, a distance of 7,828 nautical miles (14,497 km or 9,008 mi). The cruising airspeed of the 787 is Mach 0.85 (488 kn; 903 km/h; 561 mph).
The 787-8 falls short in terms of fuel efficiency when compared to other super-economic options. However, Boeing still tops Airbus in a fuel efficiency comparison, but not by much. The 787-10 is the most fuel-efficient of the larger wide-body planes.
The 787 Dreamliner is a pioneering airliner in its use of composite materials as the primary material in the construction of its airframe. Boeing worked to trim excess weight, and some parts were redesigned to include more use of titanium.

The 787's lighter composite structure reduces fuel use by up to 25%
The Boeing 787 Dreamliner is a long-range, mid-size wide-body, twin-engine jet airliner. It is Boeing's most fuel-efficient airliner, with a 20% improvement in fuel efficiency compared to the Boeing 767. This was achieved through the use of composite materials as the primary material in the construction of its airframe, as well as the selection of new engines: the Rolls-Royce Trent 1000 and General Electric GEnX. The 787 was designed to be the first production airliner with a fuselage comprising one-piece composite barrel sections instead of multiple aluminium sheets and fasteners used on existing aircraft.
The extensive use of composites in the 787's design contributes to its improved fuel efficiency. Composites, such as polymer matrix composites and carbon fibre composites, offer a higher strength-to-weight ratio than traditional aircraft materials. This allows the 787 to be a significantly lighter aircraft, improving its fuel efficiency. The use of composites also reduces the need for structural reinforcement, allowing for larger windows without compromising the aircraft's strength.
Carbon fibre composites, in particular, are utilised in various components of the 787, including the fuselage, wings, tail, doors, and interior. Each 787 contains approximately 32,000 kg of Carbon Fibre Reinforced Plastic (CFRP), made with 23 tons of carbon fibre. The carbon fibre composites are oriented in specific directions to maximise strength along the load paths, enhancing the aircraft's structural integrity while keeping weight to a minimum.
Additionally, the use of thermoplastic polymers, such as polyether ether ketone (PEEK), in aircraft structures has gained interest due to its unique properties. PEEK composites offer high strength, flexibility, damping, and resistance to weather and chemical conditions. These properties enable the composite to sustain high dynamic loads during flight operations, further contributing to the aircraft's performance and fuel efficiency.
The strategic use of polymer composites in aerospace engineering has had a significant influence on aircraft design and manufacturing. Polymer composites, formed of a matrix material reinforced with high-strength fibres, provide superior mechanical properties that make them ideal for achieving lightweight construction and exceptional performance. The use of polymer composites in the 787's design contributes to its overall fuel efficiency gains, helping to reduce fuel consumption by up to 25% compared to its predecessor.
