Patent ID: 8019574

Claim:
A method for modeling of a blended wing body (BWB) comprising: receiving as an input to a computer system a plurality of keep-out points representing a payload module; creating a faceted minimum volume that encloses all keep-out points; finding a local maximum height of the payload module; offsetting a planform leading edge by a parameter, L, determined responsive to the local maximum height to produce a L/H curve; defining a leading edge curve with first and second segment lines; shifting the leading edge curve to touch the L/H curve; determining trailing edge thickness/closeout angle constraint curve from approximate airfoil closure angle allowed; constructing a trailing edge curve; shifting the trailing edge curve to touch the thickness/closeout angle constraint curve; defining a trapezoidal wing; trimming the leading edge curve and blending the trailing edge curve with two piecewise linear segments; creating airfoil sections surrounding the payload keep-out points to create a centerbody; defining thickness, camber, twist and shear of the trapezoidal wing; defining sections in the transition region between centerbody and trapezoidal wing; and lofting the BWB with all the defined sections as an output of the system.
