Abstract : A review of the statistical experimental designs which are relevant to the selection process of the design variables is made. Although several aerospace industries still use Latin Space techniques, the inherent shortcomings of the approach are not recognized. Optimal aircraft designs which are derived from such a deficient method become suspect, and reliability and cost saving can both become unattainable. An alternate approach, called D-optimal design, which has several advantages due to its reliability and efficiency, is discussed. The statistical design techniques which have great usefulness in the computer aided design of systems such as aircraft made a great deal of impression on the imagination of Hans von Ohain. His interest and support in this area not only provided much inspiration to the work performed at AFFDL, but also demonstrated the extraordinary openness of his mind to many new and innovative ideas which he cherishes with great interest and enthusiasm.
