According to the bird-impact-resistant reinforcer for the front edge of the A-shaped airplane empennage, a reinforcer supporting plate is fixed between side plates on the two sides of the bird-impact-resistant reinforcer, and the opening end of the bird-impact-resistant reinforcer is fixedly connected with a front edge auxiliary beam of the airplane empennage. The anti-bird-impact reinforcers are located between a leading edge skin and a leading edge auxiliary beam in the leading edge of the airplane empennage, and are distributed between 0% and 100% of the wingspan in the spanwise direction of the airplane empennage. The rigidity is improved through the reinforcer supporting plate, a bird body is effectively cut, front impact is changed into side impact, impact energy is dispersed, and the integrity of the empennage structure and the aerodynamic shape of the empennage are guaranteed. It can be guaranteed that the front edge of the empennage has enough strength and rigidity, so that the structural mass of the empennage is structurally reduced, the lightweight requirement of aircraft structural design is better met, the contradiction between the better bird strike resistance and the lighter total mass of the empennage in the empennage structural design of a certain type of aircraft is solved, and the empennage structure design of a certain type of aircraft is improved. And a new scheme is provided for the structural design of the airplane empennage in the future.
一种A字形飞机尾翼前缘的抗鸟撞加强件,在抗鸟撞加强件的两侧侧板之间固定有加强件支板,并使抗鸟撞加强件的开口端与飞机尾翼的前缘辅助梁固定连接。抗鸟撞加强件位于飞机尾翼前缘内的前缘蒙皮和前缘辅助梁之间,沿飞机尾翼展向分布于翼展0~100%之间。本发明通过加强件支板提高了的刚度,有效地切割鸟体,变正面撞击为侧面撞击,分散了撞击能量,保证尾翼结构的完好性及尾翼的气动外形。本发明能够保证尾翼前缘有足够的强度和刚度,从而从结构上减轻尾翼的结构质量,更好地满足了飞机结构设计的轻量化要求,解决了某型机的尾翼结构设计中存在的更优的抗鸟撞性能与更轻的尾翼总质量之间的矛盾,为未来的飞机尾翼结构设计提供了一种新的方案。
