Numerical analysis of supersonic transport wings was carried out. The drag reduction obtained by using the warped wing design technique is from 0.0006 to 0.0010 in supersonic cruise condition. It is also clarified that the drag reduction by use of Euler analysis is less than that by the linear method, because the flow mechanism in supersonic region is essentially non-linear. Finally it is shown that the cranked arrow wing-body configuration has the best lift to drag ratio in supersonic cruise condition in comparison with delta or ogee wing-body configuration.
