Which technology enables the Boeing 787 to use less fuel?

The technology that enables the Boeing 787 to achieve significant fuel efficiency is primarily found in the combination of new engine technologies and lighter materials. The engines on the 787 are designed to be more fuel-efficient, incorporating advanced aerodynamic designs and materials that reduce weight and drag. Additionally, the use of composite materials in the aircraft's structure contributes significantly to weight reduction, allowing the 787 to operate more efficiently and consume less fuel during flight.

By utilizing these advanced engine technologies, which often feature improved compressor designs and larger fan blades, along with lighter materials that make the overall aircraft structure more efficient, the Boeing 787 can achieve better fuel economy compared to older aircraft models. These innovations collectively enable airlines to reduce operating costs and environmental impact, making them a vital component of modern aviation design.
