摘      要：Based on the supercritical"wing1"which was released in the DPW-III conference,multi-objective optimization has been done to increase the lift-drag ratio at cruise condition and improve transonic buffet boundary and drag-rise ***-Henne shape functions are used to represent the bump *** the design optimization to increase lift-drag ratio,the objectives involve the cruise point and three other off-design points *** the other optimization process to improve buffet and drag-rise performance,three buffet onset points near the cruise point and one drag-rise point are selected as the design ***-dominating sort genetic algorithm II(NSGA-II)is used in both ***,individual analysis for every selected point on the Pareto frontier is conducted in order to avoid local convergence and achieve global *** of optimization for aerodynamic efficiency show a decrease of 11 counts in drag at the cruise *** at nearby off-design points are also reduced to some *** approaches are made to improve buffet and drag-rise characteristics,resulting in significant improvements in both ways.
