ANALYSIS OF AIRPLANE DESIGN BY SIMILARITY CONSIDERATIONS

Approximately 80 aircraft are analyzed with this method. These aircraft include all sizes and speeds ranging from the DC-3 to the very large transports and proposed SST's. The basic scheme of this similarity approach is to first express the operating conditions in dimensionless form and to then relate this form to non-dimensional design parameters. The coefficient and parameters obtained in this manner are calculated for each airplane and plotted against the vehicles maximum take-off weight. These plots reveal design trends with respect to size, speed, and the operation of the square-cube law on stresses. Included is an up-dated version of Gabrielli's and von Karman's specific resistance plot from "What Price Speed?" with the remarkable result that their limit line still holds as a minimum power requirement.
