The invention belongs to the field of an airplane body design, and relates to an airplane bird-impact-resistant structure. By arranging multiple groups of upper-layer composition plates and lower-layer composition plates, during bird impact, the upper-layer composition plates are firstly impacted, and then pass through the lower-layer composition plates to reach a front-end frame web plate; and the first aluminum honeycomb panel of the upper-layer composition plate and the second aluminum honeycomb panel of the lower-layer composition plate have strong energy absorption and shock absorption effects, the bird impact resistance of the front portion of a protected structure of an airplane is effectively improved, meanwhile, the two layers of composition plate structures can support each other, the structure is stable, an effective protection effect on system equipment is achieved. The upper-layer composition plate is attached to the system equipment so that the upper-layer composition plate can adopt an area as large as possible, and a more effective protection effect is ensured.
本申请属于飞机机体设计领域,为一种飞机抗鸟撞结构,通过设置多组上层组合板和下层组合板,鸟撞时上层组合板先受到冲击、而后经过下层组合板才到达前端框腹板,上层组合板的第一铝蜂窝板和下层组合板的第二铝蜂窝板均具有较强的吸能和减震作用,有效提高飞机被保护结构前部的抗鸟撞性能,同时两层组合板结构能够相互支撑,结构稳定,对系统设备起到有效的保护作用,通过将上层组合板与系统设备相贴设置,保证上层组合板可以采用尽量大的面积,以保证更有效的保护效果。
