Abstract : Research investigations accomplished during the period 1 April 1962 to 1 April 1963 on Mach 3 supersonic transport structural concepts are reported. Structural design criteria are established, and stainless steel and titanium materials are investigated. Promising wing, fuselage, and control surface structural concepts are selected, and structural analyses procedures and design charts are developed. Thermal analyses including modifications to a computer program are described. Panel and joint specimen designs are described, and status of their manufacture and testing is reported. The designs and manufacturing status of wing box and fuselage cabin wall test specimens are presented along with plans for their structural and thermal tests. Investigation of variable sweep wing structures including redundant force analyses of the large diameter bearing pivot concept is reported. (Author)
