摘要： Lofting of a Blended Wing Body air vehicle is accomplished by first determining the required payload volume of the air vehicle. The payload volume is then analyzed to determine a list of corner points of the payload volume. The list of points is passed to a Loft Module as keep-out points and a body portion of the blended wing body is established using a faceted minimum volume which encloses all of the provided keep-out points. A trapezoidal wing shape and size is then determined to accommodate aerodynamic performance requirements. 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 all other point coordinates and all tangents and remaining curvatures to smoothly enclose the payload volume in a first set of aerodynamic sections are defined. The aerodynamic requirements of the trapezoidal wing including Wing Thickness, Camber, Twist and Shear establish a second set of aerodynamic sections and sections in a transition region between the body portion and the trapezoidal wing are then defined. The blended wing body is then lofted based on the first plurality of sections, second plurality of sections and transition sections.

摘要： A blended wing body cargo aircraft is disclosed. A body section defines a cargo volume, where an outer surface of the body section is shaped to provide an aerodynamic lifting surface. A cargo door and ramp structure is located in an aft end of the body section and is shaped to conform to an outer shape of the aerodynamic lifting surface when in a closed position. A control surface has a slightly cambered downward shape, and is positioned substantially near an aft end of the cargo door and ramp structure.
