Abstract
An aircraft fuselage frame assembly includes a first lower frame element having a cross member and a curved fuselage tub frame. A second upper frame element of the assembly has a cross member and a curved upper frame segment. A third frame element of the assembly is made of a cross member section, floor strut section and frame section. The third frame element is formed as a single, integral triangle element having a hypotenuse that is curved to adopt a curvature of the aircraft fuselage and joining portions at angle areas of the triangle. A lower frame link is joined to the first upper frame and at a first angle area of the triangle element; an upper frame link is joined to the second upper frame and at a second angle area of the triangle element; and a floor cross member is joined at a third angle area of the triangle element.
