Abstract : The application of optimization techniques to aircraft configuration design is discussed. Advantages and disadvantages of automated search methods are compared with those of parametric analysis methods. The formulation of the design problem for direct search methods using a normalization procedure is developed. Various direct methods are briefly described. Operational results using several of these methods are reported for aircraft configuration design problems. Gradient methods are found to give disappointing results when compared with certain non-gradient methods. Reasons are suggested for this behavior. The future promise of 'man-computer interactive design' is briefly described. (Author)
