What are blended wing bodies?
A blended wing body (bwb), also known as blended body, hybrid wing body (hwb) or a lifting aerofoil fuselage, is a fixed-wing aircraft having no clear dividing line between the wings and the main body of the craft. The blended-wing–body (bwb) is an example of an advanced aircraft design with low-noise features. The design differs from the traditional tube-and-wing configuration; the vehicle has overwing-mounted engines that introduce shielding of engine noise, as well as simplified high-lift devices that reduce airframe noise.
