Abstract:
1. A fitting for introducing high forces into a fuselage cell of an aircraft stiffened with a multiplicity of frames, the fitting comprising: a lug shackle, arranged in which is a lug for introducing forces emanating from undercarriage components, and a shoulder plate for bearing against the inside of the skin of the fuselage cell, the shoulder plate being arranged on the inside of the fuselage cell, at least one approximately vertically upward pointing fastening shackle being arranged on the shoulder plate for the connection to a frame web, and the lug shackle, which is directed vertically downward, being arranged underneath the shoulder plate and guided to the outside through a clearance in the skin of the fuselage cell; wherein the forces introduced into the fuselage cell are transferred between the undercarriage and the fuselage cell by way of the fitting; wherein loads from the skin of the fuselage cell are introduced into the frame web by shearing; and wherein radial loads are introduced by way of shearing of the shoulder plate into the skin of the fuselage cell.
