A review on aircraft joints design

Abstract

Purpose The purpose of this paper is to present a review about sizing of joints, from the static and fatigue points of view. A discussion about advantages and disadvantages of each joining technology, among the ones mentioned above, will be presented. Design/methodology/approach Although many other aspects will be discussed, emphasis will be given to the joint fatigue behavior, and fatigue test results will be presented and discussed. Findings This paper is a subject review, where no new findings are presented. However, the comparison of fatigue test results for mechanically fastened joints and friction stir welding joints will show the advantages of the latter. Practical Implications With the information presented, the authors expect to provide some guidelines that will help to improve future joint designs. Originality/value The review information contained in this paper may be used as reference for aircraft joint design.

“…Those types of joints are shown in figure 3. The correct understanding of the load distribution in joints used in aeronautical components is of paramount importance for their design, as discussed by Chaves and Fernandez [6]. In addition, having means to correctly obtain the margin of safety for each of these joints accurately becomes crucial, since any complication during a field operation, it is necessary to use these safety margin values for evaluation, and correct modification, if necessary.…”

Optical Analysis of the Impact Transmission in Steel Sheet Arrays with Bolted-Type Joints

“…Rivets are often used in the fuselage of airplanes, screws and nuts are spent in mechanical and electrical mechanisms, and welding is seen in electrical plates and structural forges, to mention some of the most common ones. Structural joints are highly important as their selection depends on many factors, such as structure, geometry, load conditions, fabrication process, and maintenance requirements [23]. NASA has tested structural joints with one bolt but a different set of rows.…”
