冲击抵抗和损坏容限改善的飞行器机身段
摘要：
冲击抵抗和损坏容限改善的飞行器机身段。本发明涉及一种经受外部物体冲击的飞行器机身段(32)，该飞行器机身具有有至少一个竖直对称平面(A-A)和中心纵向轴线的弯曲形状，并包括蒙皮(35)和布置成垂直于所述纵向轴线(33)的多个环形框架(37)，飞行器机身段(32)还包括安装飞行器支撑结构(41，43)上的至少一个内部网状结构(51，53)，其中所述支撑结构包括附接到所述蒙皮(35)并与所述环形框架(37)互连的纵梁(39)，所述内部网状结构(51，53)布置成用于与所述蒙皮(45)形成至少一个封闭的隔室(75)，以提高其对于所述冲击的抵抗力以及其损坏容限。
摘要（英）：

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 a central longitudinal axis, and comprising a skin (35) and a plurality of ring frames (37) arranged perpendicularly 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), which 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 thereof to damage from said impacts.
