A compilation of data involving use of materials on selected aircraft areas of two types of aircraft has been accomplished. Wing surface, wing internal section, fuselage panel and landing gear data concerning the use of aluminum, steel and titanium have been compiled for a large cargo aircraft C-5 and a supersonic fighter. Data consists of mechanical property items, corrosion, producibility, maintainability, availability and cost pertaining to the above sections and material. Direct comparison of the materials in conjunction with the study parameters in each application has been made for the two aircraft and presented. Also included is the effect of selected mechanical property improvements on the weight of aircraft structure. By assuming certain percentages of improvements in the property levels of the three materials considered, computerized data was collected indicating the effect of the improvements on weight of each of the three sections evaluated. Appropriate curves have been generated indicating those material areas warranting development.
