Advanced Design Studies and Unusual Concepts

Blended Wing-Body Concept

from the Virginia Tech Aircraft Design Information Sources pages

Robert H. Liebeck, Mark A. Page, Blaine K. Rawdon, Paul W. Scott, and Robert A. Wright, “Concepts for Advanced Subsonic Transports,” NASA CR 4624, Sept. 1994. This was the first report describing the blended wing-body concept in some detail. This is a good place to start to see the evolution of the thinking and changes in the configuration as more and more technical work was done.

Mark A. Potsdam, Mark A. Page and Robert H. Liebeck, “Blended Wing Body Analysis and Design,” AIAA Paper 97-2317, June 1997. Applied Aero Proceedings, Vol. 2, pp. 799-805. This paper summarizes the concept and then presents some details on the aerodynamic work. They rediscovered what happens when you squeeze the chord at midspan. Because the spanload will tend to be smooth, when the chord is small the section lift coefficient becomes large, and they found separation in this area of the wing. All in all a good paper on configuration design.
