Embodiment Construction

[0015] Such as figure 2 As shown, an anti-bird strike structure at the leading edge of an aircraft includes a leading edge skin 1 and a rib plate 2. In the cavity of the leading edge skin 1, a hollow thin-walled structure is installed at a certain distance from the leading edge skin 1. Energy absorbing tube 5.

[0016] The hollow thin-walled energy-absorbing pipe 5 is fixed on the beam through the bracket 4 . The bracket 4 has a bayonet matching with the hollow thin-walled energy-absorbing tube 5 .

[0017] The hollow thin-walled energy-absorbing pipe 5 is integral or segmented. The hollow thin-walled energy-absorbing tube 5 is filled with energy-absorbing material. Various types of cables are installed in the hollow thin-walled energy-absorbing tube 5 .

Abstract

The invention relates to the field of aircraft structure design, in particular to an aircraft leading edge anti-bird collision structure. At present, the bird impact resistance design and installationstructure of the leading edge structure is complex, the structure efficiency is low, the weight of the structure is large, and the effective space is affected. A lead edge bird impact resistant structure of that aircraft comprises a leading edge skin and a rib plate, and a hollow thin-wall energy absorb tube is arranged in the cavity of the leading edge skin at a distance from the leading edge skin. The invention has the advantages of simple structure, simple installation, high structure efficiency and low weight cost.

Description

technical field [0001] The invention relates to the field of aircraft structure design, in particular to an aircraft front edge anti-bird strike structure. Background technique [0002] There is a certain probability that the aircraft will be hit by birds during flight. To ensure flight safety, the aircraft must have the specified ability to be hit by birds. Generally, the areas where the aircraft is hit by birds are the nose, the lip of the engine, and the leading edge of the airfoil. For the flying leading edge structure, on the basis of satisfying the aerodynamic characteristics of the aircraft, it is necessary to take into account the structural strength, weight, equipment space layout, process manufacturing and maintainability of the aircraft. [0003] At present, the anti-bird strike design of the leading edge structure is mainly in the aspect of structural deformation and energy absorption. The improvement is improved by increasing the thickness of the leading edge sk...
