Abstract

A design study of wing tip devices at high and low speeds is described. The basis of the design study is an equivalent drag approach containing both aerodynamic drag gain and structural weight penalty. A comprehensive parameter study is carried out using a rapid databased aerodynamic prediction tool named Lift and Drag Component Analysis (LIDCA). Detailed validation studies of the method at high lift and high speed have demonstrated sufficient accuracy. RANS computations of the selected wing tip designs confirm the predicted benefits at cruise condition. The results of the most effective wing tip designs are analysed at both flight conditions. Finally, options for improving the performance at take-off are suggested.
