Abstract

"Aerodynamic characteristics of a dual wing aircraft were analyzed with variations in airfoil sections and chord ratios over existing equal chard ratio dual wing and monoplane aircraft designs. Two- and three-dimensional aerodynamic studies were conducted to find the wing geometry which would create the minimum cruise drag. The two-dimensional aerodynamic data was obtained from a multi-element inviscid vortex panel program coupled to a momentum integral boundary layer program to account for the aerodynamic coupling between the wings. With this data, a three-dimensional vortex lattice program calculated the three-dimensional aerodynamic data. compared to an equal chard ratio dual wing aircraft, lower drag was found for the unequal chard ratio dual wing aircraft. this resulted from the two-dimensional aerodynamic data of the latter. In addition, these dual wing designs obtained superior performance compared to the equivalent monoplane"--Abstract, page iii.
