摘要:
The invention provides an internal shield (31) inside the rear fuselage (11) of an aircraft having a propulsion system formed by two engines (13) mounted on each side of it. The internal shield (31) is located in a suitable place inside the rear fuselage (11) for covering the possible trajectories of fragments detached from one of said engines (13) in a failure event that would impact critical elements of the opposite engine. The internal shield (31) comprises an ensemble of fluid containers belonging to aircraft sub-systems, such us particularly the potable water and waste water sub-systems, with enough fluid for providing the energy absorption capability required for stopping said fragments. The invention also refers to an aircraft having said internal shield (31).

The invention refers to a panel structure (1) for an aircraft comprising at least one composite layer (3, 4), and at least one net-shaped layer (2) attached to the at least one composite layer (3, 4), wherein the net-shaped layer (2) comprises a material suitable to improve the impact resistance of the panel structure (1). The net-shaped layer (2) can be used to attach two composite layers (3, 4). Alternatively, the net-shaped layer (2) can be attached to a surface of one composite layer (3, 4). In this last case, the net-shaped layer (2) may be joined to a laminate sheet material (5), and filled with a foam material (6). The invention provides an impact reinforced panel structure (1) capable of withstanding any impact, such as a blade release, or a bird strike, without substantially modifying the manufacturing process.

Improved impact-resistant and damage-tolerant aircraft fuselage. The invention relates to a section (32) of the fuselage of an aircraft suffering impacts from external bodies, the fuselage of the aircraft having a curved form with at least one vertical plane of symmetry (A - A) and central longitudinal axis, and comprising a skin (35) and a plurality of ring frames ( 37) arranged perpendiculary to said longitudinal axis, said section (32) of the fuselage also comprising at least one reticular internal structure ( 51, 53) mounted on a support structure ( 41, 43), wich includes longitudinal beams (39) connected to the skin (35) and interconnected with said ring frames (37), said reticular internal structure ( 51, 53) being arranged in order to create at least one closed cell (75) with the skin (45) in order to improve the strength thereof and the tolerance to damage from said impacts.
