A joggle is primarily used for which purpose in aircraft construction?

A joggle is a specific type of bend or offset made in sheet metal that facilitates the connection and alignment of various panels in aircraft construction. This feature is essential because it allows for a proper fit between adjacent metal sheets, ensuring structural integrity and minimizing potential stress points that could lead to failure in critical areas. The joggle serves to create a step or offset, permitting the sheets to overlap correctly, which is particularly important in areas that face dynamic loads or require a tight seam to prevent leaks or other issues.

While aesthetic considerations, weight reduction, and fuel efficiency are important factors in aircraft design, the primary function of a joggle is its practical application for effectively connecting sheets of metal in a way that enhances the overall structural performance and durability of the aircraft.
