Blended wing body
A blended wing body (BWB), also known as blended body, hybrid wing body (HWB) or a lifting aerofoil fuselage,[1] is a fixed-wing aircraft having no clear dividing line between the wings and the main body of the craft.[2] The aircraft has distinct wing and body structures, which are smoothly blended together with no clear dividing line.[3] This contrasts with a flying wing, which has no distinct fuselage, and a lifting body, which has no distinct wings. A BWB design may or may not be tailless.
The main advantage of the BWB is to reduce wetted area and the accompanying form drag associated with a conventional wing-body junction. It may also be given a wide airfoil-shaped body, allowing the entire craft to generate lift and thus reducing the size and drag of the wings.
The BWB configuration is used for both aircraft and underwater gliders.
