An alternative approach to induced drag reduction
Aviation, 2021 Induced drag constitutes approximately 40% of the total drag of subsonic civil transport aircraft at cruise conditions. Various types of winglets and several non-planar concepts, such as the C-wing, the joined wings, and the box plane, have been proposed

Handling Qualities of a Blended Wing Body Aircraft [PDF]
AIAA Atmospheric Flight Mechanics Conference, 2011 The blended wing body (BWB) is a tailless aircraft with the potential to use 27% less fuel than a conventional aircraft with the same passenger capacity and range. The primary purpose of the current study was to determine the handling qualities of the BWB, using piloted-handling trials in a moving-base simulator.
