Since its introduction, the 787 has become a cornerstone of modern aviation, offering airlines and passengers a blend of innovation, sustainability, and performance. This blog dives deep into the history, design, engines, operators, and impact of the Boeing 787, providing an informative guide for aviation enthusiasts, travellers, and industry professionals alike.
History of the Boeing 787 Dreamliner
Origins and Development
The Boeing 787 program was launched in April 2004, with All Nippon Airways (ANA) placing the initial order for 50 aircraft. Boeing aimed to create an aircraft that could replace the ageing Boeing 767 and compete with Airbus’s A330 and A350 models. The Dreamliner was designed to be a game-changer, focusing on fuel efficiency, reduced operating costs, and enhanced passenger experience.
The development process was ambitious, with Boeing introducing groundbreaking materials and technologies. The 787 was the first commercial airliner to use composite materials for over 50% of its primary structure, including the fuselage and wings. However, the program faced significant challenges, including supply chain issues, production delays, and technical setbacks. Originally scheduled for delivery in 2008, the first 787-8 was delivered to ANA in September 2011 after extensive testing and refinements.

Design and Features of the Boeing 787
The Boeing 787 Dreamliner stands out for its innovative design, which prioritises efficiency, comfort, and environmental sustainability.
Composite Materials
The 787’s airframe is constructed with 50% composite materials (carbon-fibre-reinforced polymers), 20% aluminium, 15% titanium, 10% steel, and 5% other materials. Composites reduce weight, improve fuel efficiency, and resist corrosion, extending the aircraft’s lifespan.
Aerodynamic Efficiency
The 787 features raked wingtips and a sleek aerodynamic profile, reducing drag and improving fuel efficiency by approximately 20% compared to older aircraft like the Boeing 767. Its design allows for higher cruising speeds (Mach 0.85) and longer ranges.
Passenger Comfort
The Dreamliner is renowned for its passenger-centric features:
-
Larger Windows: Electrochromic windows that dim electronically, allowing passengers to control light without shades.
-
Cabin Pressure: Pressurised to a lower equivalent altitude (6,000 feet vs. 8,000 feet), reducing fatigue.
-
Humidity Control: Higher cabin humidity levels improve comfort on long flights.
-
Noise Reduction: Advanced sound-dampening materials create a quieter cabin.
-
LED Lighting: Customizable lighting to mimic natural daylight cycles, reducing jet lag.
Variants
The 787 family includes three variants:
-
787-8: The smallest, with a range of 7,305 nautical miles and capacity for 242 passengers (two-class configuration).
-
787-9: A stretched version with a range of 7,635 nautical miles and capacity for 290 passengers.
-
787-10: The largest, with a range of 6,430 nautical miles and capacity for 336 passengers.

Engines of the Boeing 787
The Boeing 787 is powered by two engine options, both designed for optimal performance and efficiency:
1. General Electric GEnx
- Type: High-bypass turbofan
- Thrust: 53,000–74,000 lbf (depending on variant)
- Features: Advanced composite fan blades, low emissions, and high fuel efficiency.
- Usage: Preferred by many airlines for its reliability and performance on long-haul routes.
2. Rolls-Royce Trent 1000
- Type: High-bypass turbofan
- Thrust: 53,000–74,000 lbf
- Features: Incorporates bleedless engine technology, reducing weight and improving efficiency.
- Usage: Popular among operators like ANA and British Airways.
Both engines contribute to the 787’s 20–25% better fuel efficiency compared to older aircraft, thanks to advanced aerodynamics and lightweight materials. The choice of engine depends on the airline’s operational needs and maintenance agreements.
| Engine Model | Thrust Range (lbf) | Key Features |
|---|---|---|
| GEnx | 53,000–74,000 | Composite fan blades, low emissions |
| Trent 1000 | 53,000–74,000 | Bleedless design, high efficiency |
