Weldbond Flight Component Design/Manufacturing Program
Abstract
This report describes the weldbond process developments, component analyses, and tests that led to the design and manufacture of a C-130H weldbonded fuselage component. The weldbonded fuselage component was installed on C-130H Serial No. AF73-01592 for flight evaluation. This development program was accomplished in five tasks: namely, process development, engineering data development and component design, component fabrication, structural testing and qualification, and component installation. During the course of the program, thirteen candidate surface preparations and eighteen candidate adhesives were evaluated for selection of the weldbond process used in fabrication of test specimens, test components, and the flight component. Weldbonded elemental specimens and sub-scale components were fabricated and tested for establishment of joint static strength, fatigue strength, residual strength after environmental exposure, crippling strength, shear and compression stability, and sonic fatigue. In addition, a full-scale weldbonded fuselage component assembled into a test specimen in conjunction with two standard production fuselage components was comparative strength tested. Also, nondestructive inspection methods for weldbonded joints and cost data were developed.
