耐冲击和耐损伤的飞机机身

Impact resistant and damage tolerant aircraft fuselage
Abstract:
Aircraft fuselage section (32) subjected to impacts of external bodies, the aircraft fuselage having a curved shape with at least a vertical symmetry plane (A-A) and a central longitudinal axis and comprising a skin (35) and a plurality of frames (37) arranged perpendicularly to said longitudinal axis (33), the aircraft fuselage section also comprising at least an inner reticular structure (51, 53) mounted on a supporting structure (41, 43) comprising longitudinal beams (39) attached to the skin (35) and interconnected with said frames (37), said inner reticular structure (51, 53) being arranged for creating at least one closed cell (75) with the skin (35) for improving its resistance and its damage tolerance to said impacts. Said inner reticular structure (51, 53) can be formed by panels (61), rods (65, 65′), cables (67, 67′) or belts (69, 69′).
Abstract(Chinese):

飞机机身部分受到外部物体的撞击，飞机机身具有至少具有垂直对称平面（AA）和中心纵向轴线的弯曲形状并且包括皮肤（35）和多个框架（37） 飞行器机身部分还包括安装在支撑结构（41,43）上的至少一个内部网状结构（51,53），该内部网状结构（51,53）包括连接到皮肤（35）的纵向梁（39） 并且与所述框架（37）相互连接，所述内网状结构（51,53）布置成用于产生具有皮肤（35）的至少一个闭孔（75），以改善其抵抗力及其对所述冲击的损伤容限。 所述内网状结构（51,53）可以由面板（61），杆（65,65'），电缆（67,67'）或皮带（69,69'）形成。
