Frame component and method for producing a frame component, frame and fuselage structure for an aircraft

A method for producing a frame component comprising:

• a central web which extends along a longitudinal direction and has an inner edge region with respect to a radial direction running transversely with respect to the longitudinal direction and an outer edge region with respect to the radial direction;
• an inner web which is bent from the inner edge region of the central web towards a first side;
• an outer web which is bent from the outer edge region of the central web towards the first side, wherein the central web, the outer web and the inner web are produced integrally from a metal sheet and together define a C-shaped cross section of the frame component;
• and
• at least one stringer recess which is formed in the outer web and in the outer edge region of the central web;
• wherein the central web has, in a region of the stringer recess, a first reinforcing formation which forms a protrusion on the first side of the central web;
• the method comprising:
• forming a circumferential edge, which defines the at least one stringer recess, on a metal sheet by a machining process;
• forming the central web, the inner web, and the outer web by bending over rim regions, which extend from the circumferential edge, relative to a central region of the metal sheet, the central region forming the central web;
• and
• forming the first reinforcing formation by deforming the central web by at least partially angling a recess edge of the central web defining the stringer recess towards the first side.

A frame component for a frame of a fuselage structure of an aircraft, the frame component comprising:

• a central web which extends along a longitudinal direction and has an inner edge region with respect to a radial direction running transversely with respect to the longitudinal direction and an outer edge region with respect to the radial direction;
• an inner web which is bent from the inner edge region of the central web towards a first side;
• an outer web which is bent from the outer edge region of the central web towards the first side, wherein the central web, the outer web and the inner web are produced integrally from a metal sheet and together define a C-shaped cross section of the frame component;
• and
• at least one stringer recess which is formed in the outer web and in the outer edge region of the central web;
• wherein the central web has, in a region of the stringer recess, a first reinforcing formation which forms a protrusion on the first side of the central web;
• and
• wherein:
• at least one second reinforcing formation in a form of a bead, which is introduced from a second side of the central web and forms a protrusion on the first side of the central web, is formed in a bent region connecting the inner edge region of the central web and the inner web;
• or
• the frame component has a connecting region for connection to a further frame component, which connecting region forms one end of the frame component in the longitudinal direction, and wherein the central web, at an end region adjoining the connecting region with respect to the longitudinal direction, has a third reinforcing formation in a form of a bead which is introduced from a second side of the central web, forms a protrusion on the first side of the central web and at least partially extends along the radial direction.
