Abstract: An airfoil or wing is connected to the body of an aircraft or spacecraft through a main connector comprising metal and nonmetal components. Tension load take-up loops and a pressure load take-up core are arranged or held in a metal grommet which in turn is centered relative to and integrated with a main connector bushing. Thus, the tension loads are solely introduced into the wing structure through the tension loops and pressure loads are taken up solely by the pressure core, whereby the advantages of fiber compound materials are optimally utilized.

Abstract: The present shackle is especially constructed for securing a wing to the fuselage of an aircraft or of a spacecraft. For this purpose the elements of the shackle intended for taking up pressure and tensile forces as well as the elements providing the necessary structural stability are made of fiber compound materials such as carbon or boron fibers.
