Blended Wing Body concept


A completely different path that Boeing may choose to pursue in the near future is the Blended-Wing-Body, or BWB. Despite your rather unappreciative comments, some of our staff have had the opportunity to meet with and talk to one of the concept's creators, and we've found it to be a most interesting design. The BWB is related to the flying wing, but is a somewhat more sophisticated concept that resulted from a study to determine the optimum low-drag shape to contain a given volume of passenger space. The resulting fuselage resembles a flattened sphere that tapers down and blends into the outboard wings, hence the name Blended-Wing-Body. The thick center-section could hold some 500 to 800 passengers, as illustrated below. Additional studies have focused on smaller variants in the 250- to 300-passenger range, and a recently reported study indicated that a cruise speed of Mach 0.9 over a range of 7,500 to 8,900 nm (13,875 to 16,465 km) might be an optimum design point.
