The report presents a dynamic gust analysis of the Boeing Model 720B airplane and outlines two procedures for assessing gust design strength for future civil transports. The procedures outlined are based on two approaches. The first is the design envelope approach, the second is the flight profile approach. The 720B airplane was studied for both concepts, first, by using the bending moment on the wing, fuselage, and vertical tail as indicies of their strengths. The second step was to study the more critical structural areas using a joint probability stress analysis approach developed by Boeing. The results of these analyses indicate that the design envelope and flight profile approaches give results that are in general agreement.
