Abstract

The invention relates to a horizontal tail front edge for a bird strike-resisting airplane. An upper honeycomb sandwich layer, a lower honeycomb sandwich layer, a front edge reinforcing member and an aerofoil lining layer are arranged among spans on the horizontal tail front edge in a spanwise mode along a horizontal tail of the airplane; one angle of the front edge reinforcing member is positioned at the front end of the horizontal tail front edge; the upper honeycomb sandwich layer and the lower honeycomb sandwich layer which are in a shape of a parallelogram are fixed on upper and lower internal surfaces of a horizontal tail skin respectively, the edge of one vertex angle of each honeycomb sandwich layer is fixed with surfaces of the front edge reinforcing member and the horizontal tail skin respectively, and the edge of the other vertex angle is fixed with the surfaces of the horizontal tail skin and the aerofoil lining layer; and the honeycomb sandwich layers and the front edge reinforcing member are coated between the aerofoil lining layer and the internal surfaces of the horizontal tail skin by the aerofoil lining layer. In the horizontal tail front edge, birds are cut by the front edge reinforcing member, the impact force of the birds is absorbed by the honeycomb sandwich layers, and an internal structure of the horizontal tail front edge is protected against damage bythe aerofoil lining layer. The horizontal tail front edge is also suitable for vertical tails, aerofoil front edges and all beam edges which are likely to be subjected to bird strike on the airplane.

Description

technical field [0001] The invention relates to the field of civil aircraft structure design, in particular to a flat tail leading edge structure. Background technique [0002] A bird strike accident refers to an accident in which an aircraft such as an airplane flying in the air collides with a flying bird. With the rapid development of the civil aviation industry, civil aircraft bird strikes have become one of the most serious safety threats to civil aviation. According to relevant reports of United Airlines, from 1990 to 2008, American civil aviation reported 89,727 collisions between animals and civil aviation aircraft, 97.4% of which were caused by birds. Relevant data show that the windward side of the aircraft, including the windshield, radome, engine, wing leading edge and tail leading edge, is the most vulnerable to bird strikes. There are often oil circuit systems or control lines inside the leading edge structure. Once these internal facilities are damaged by bi...
