dc.description.abstract | A new multipoint inverse design method to improve aerodynamic performance of transonic transport wings at off-design conditions is demonstrated. We minimized weighted averages of the residuals that are differences between computed and target pressures at two design points. Target pressure distributions are optimized using a genetic algorithm. It was found that characteristics of single-point design wings were transferred to dual-point design wings proportionallyto weighting factors. Through the dual-point design procedure, off-design performance of a single-point design wing is improved while preserving good performance at the primary design point. The present dual-pointdesign procedure requires about 12 times the computationalcost of a ow solver and is, therefore, very ef cient for the multipoint design of transonic wings. | en |
