Composite aircraft frame

摘要

Composite aircraft frame (1) comprising two segments (10, 20), each of these segments (10, 20) being single unitary element made in composite material and comprising at least one web (2), a stiffening structure and a fitting (4), the two segments (10, 20) being joint by the fittings (4) using rivets, forming the aircraft frame (1). The invention also refers to a method for fabricating such an aircraft frame (1).

1. An aircraft frame (1) comprising:
two segments (10, 20), each of the two segments (10, 20) being a single unitary element made of composite material, and each of the two segments (10, 20) including: at least one arc-shaped web (2) with a convex-shaped outer side wall (2ow), and a concave-shaped inner side wall (2iw) so that each of the two segments (10, 20) has an open interior, a stiffening structure with multiple components (31, 32, 33), each of which extends in a direction that is perpendicular to the convex-shaped outer side wall (2ow), and a fitting (4) arranged in a position located where a portion of the multiple component (31, 32, 33) join each other, wherein the two segments (10, 20) are joined together by the fitting (4) of each of the two segments (10, 20) using rivets (4r), thereby forming the aircraft frame (1) in a manner such that the concave-shaped inner side walls (2iw) of each of the two segments (10, 20) directly face each other.
