Abstract:
The invention provides an integrated aircraft structure, such as a fuselage, with reinforcing elements in areas of the structure that need them because they have openings or are subjected to high loads. The structure comprises a skin, a plurality of stringers and a plurality of frames with mouseholes for the passage of stringers at their crossing zones. The reinforcing elements are configured with a suitable shape to be superimposed to the stringers in said areas. A manufacturing processes of said integrated aircraft structure is also provided.
Abstract:
An aircraft structure made of composite material, comprising a skin reinforced longitudinally with stringers, and frames perpendicular to the stringers, each stringer comprising a head and two webs, and each frame having recesses in its web for the passage of the longitudinal stringers, such that an internal preform is provided in the gap existing between each stringer and the skin, filling the gap.
Abstract:
A frame of a fuselage section of an aircraft that receives external loads, such as the rear section that receives the loads of the tail planes, comprising a first sector configured specifically to withstand these external loads and a second sector along the remaining perimeter of the fuselage, said first sector comprising the following structural elements a) a foot piece to be joined to the fuselage skin; b) a head piece; c) a web comprising one or more fitting-pieces for receiving said external loads and a plurality of X-shaped pieces joined by its ends to said foot piece and said head piece; and d) two connecting pieces of the ends of said foot piece and said head piece with the second sector of the frame.
Abstract:
Frame of a fuselage section of an aircraft that receives external loads, such as the rear section that receives the loads of the tail planes, comprising a first sector (11) configured specifically to withstand these external loads and a second sector along the remaining perimeter of the fuselage, said first sector (11) comprising the following structural elements: a) a foot piece (21) to be joined to the fuselage skin (13); b) a head piece (23); c) a web (25) comprising one or more fitting-pieces (27, 27′) for receiving said external loads and a plurality of X-shaped pieces (31) joined by its ends to said foot piece (21) and said head piece (23); d) two connecting pieces (39, 39′) of the ends of said foot piece (21) and said head piece (23) with the second sector of the frame.
Abstract:
A frame (1) for fuselage shells of an aircraft, the fuselage comprising a skin (3) and stringers (4), the frame (1) including: a plurality of sections (5), the sections (5) being separated by intermediate gaps corresponding to the position of the stringers (4) in the fuselage, each section (5) having a multi-cell configuration constituted by several modular elements (6) of composite material arranged in longitudinal direction, and a continuous inner cap (7) on top of the sections (5) and the intermediate gaps.
Abstract:
A tail cone of an aircraft, more specifically a tail cone made of composite materials comprising an internal skin, an external skin surrounding the internal skin, longitudinal structural members located on the inner face of the internal skin in the longitudinal direction of the tail cone, and transversal structural members located between the external skin and the internal skin in the transverse direction of the tail cone.
