Abstract Considering the features of wedge structure on the trailing edge of aircraft wing surface during the assembly riveting, the rivets must be selected in appropriate length according to the accurate measurement of edge angle and laminated thickness of pin hole, so as to realize the double face riveting. This paper designs a special compound measure based on the requirement that wedge angle and laminated thickness of pin hole must be measured accurately by one time only, Therefore, the measurement requirements to wedge structure on the trailing edge of aircraft wing surface could be satisfied completely through the design in measure structure and the analysis on potential error.
