The New Plane Design for Future
The basic design of commercial airplanes hasn’t changed much in the past 60 years. Modern airliners like the Boeing 787 and the Airbus A350 have the same general shape as the Boeing 707 and the Douglas DC-8, which were built in the late 1950s and solidified the “tube and wing” form factor that is still in use today. This is because commercial aviation prioritizes safety, favoring tried-and-tested solutions, and because other developments — in materials and engines, for example — mean the traditional design is still relevant. However, as the industry desperately looks for ways to reduce carbon emissions, it faces a somewhat tougher challenge than other sectors precisely because its core technologies have proven so hard to move away from. The time might be ripe to try something new. One proposal is the “blended wing body.” This entirely new aircraft shape looks similar to the “flying wing” design used by military aircraft such as the iconic B-2 bomber, but the blended wing has more...
