Abstract
A required payload volume of a Blended Wing Body air vehicle is determined and analyzed for a list of corner points that is passed to a Loft Module as keep-out points to be enclosed by a body portion established using a faceted minimum volume. Trapezoidal wing shape and size are determined, a leading edge of the body portion and trapezoidal wing leading edge are trimmed and a trailing edge of the body portion and trapezoidal wing trailing edge are blended. A leading edge elevation is established and with leading edge radius as an input smoothly encloses the payload volume in a first set of defined aerodynamic sections. A second set of aerodynamic sections and transition sections between the body portion and the trapezoidal wing are defined. The blended wing body is then lofted based on the defined sections.
