The invention provides a baffle assembly and an aircraft nose anti-collision structure. The baffle assembly comprises a baffle. The baffle comprises an upper panel, a lower panel and an interlayer; the interlayer is located between the upper panel and the lower panel, and the density of the interlayer is gradually decreased in the direction from the upper panel to the lower panel. According to the baffle assembly, the gradient foamed aluminum core body is adopted in the interlayer, so that the bird strike resistance of the aircraft nose is improved, the structural weight is reduced, and the manufacturing cost is reduced. And secondly, the baffle is subjected to edge covering treatment, sealing is achieved, therefore, contact between the foamed aluminum core and water is reduced, and the situation that the service life of the structure is shortened due to the fact that the foamed aluminum core is corroded is prevented. And finally, on the basis of the conventional I-shaped beam support, a vertical beam support is added, so that the bird impact resistance of the edge part of the baffle plate is enhanced.
本申请提供了一种挡板组件及飞机机头抗撞击结构,包括挡板。所述挡板包括上面板、下面板及夹层;所述夹层位于所述上面板及所述下面板之间,且沿从所述上面板到所述下面板的方向密度递减。该挡板组件在夹层中采用了梯度泡沫铝芯体,不仅提高了飞机机头抗鸟撞性能,同时还减轻了结构重量、降低了制造成本。其次,本发明对挡板进行包边处理,实现了密封,从而减少了泡沫铝芯体与水分的接触,防止了泡沫铝芯体被腐蚀而缩短结构寿命。最后,现有工字梁支撑的基础上,增加了垂直梁支撑,增强了挡板边缘部位的抗鸟撞性能。
