The wing-design activity within the EUROSUP project on the reduction of the drag of supersonic transport aircraft and the assessment of aerodynamic design methods, is summarised. Ten partners are contributing to computational and experimental research tasks. Two linked wing-design tasks have been completed: dual-point transonic I supersonic cruise design (using linear, inverse and optimisation methods with geometric and aerodynamic constraints) and low-speed design. Three optimum configurations of the wing have been defined and are to be tested in 1998 to assess the design. Segmented leading- and trailing-edge flaps are employed at the transonic and low-speed design points. Excellent LID performance is predicted without compromising the supersonic performance. Major limitations were exposed in current computational methods for low speed design and further research is recommended in this area.
