Research on the Aerodynamic Design of A Large OFW Supersonic Airliner

An oblique flying wing with a cruise mach number of 1.41 is designed. It includes the design of the airfoil sections and a blending of these airfoil sections to create the wing. Using a parameterized airfoil shape generator, a careful tailoring of the wing planform and planform bending, twisting and wing thickness distribution are used to ensure a nearly elliptic load distribution and a minimum drag body area distribution. The lift coefficient and wing sweep are varied sequentially to arrive at an optimum inviscid design.
