A hyperbolic corrugated sandwich protective structure applied to aircraft pavement arrest

Abstract

The invention discloses a hyperbolic corrugated sandwich protection structure applied to a plane pavement for arrest. The hyperbolic corrugated sandwich protection structure comprises an upper-layer panel, a corrugated core layer and a lower-layer panel. Different from a traditional sandwich structure, the hyperbolic corrugated sandwich protection structure is characterized in that the sandwich layer is of a hyperbolic corrugated structure, an orthorhombic sinusoidal corrugated appearance is shown in the transverse and longitudinal direction of the structure, and hyperbolic corrugated sandwich boards in different geometrical shapes are structured through adjusting the amplitude, the period and the number of stacking layers of the hyperbolic corrugated sandwich layer. The invention provides an anti-impact energy absorption structure capable of being laid at the tail end of an airport pavement. When a plane accidentally rushes out of the pavement, the hyperbolic corrugated sandwich board is rolled by airplane wheels to be subjected to plastic deformation to absorb the impact energy of the plane, so that the plane can be quickly and steadily decelerated, and accordingly, the safety of passengers is protected.

Description

technical field [0001] The invention relates to an aviation emergency arresting structure, which is a hyperbolic corrugated sandwich protective structure applied to the arresting of aircraft pavement, specifically, a double-layered protective structure with impact resistance and buffering and energy absorption applied to the arresting system of aircraft pavement. Curved corrugated sandwich panel. Background technique [0002] With the increasing demand of modern human beings for the civil aviation transportation industry, accidents of aircraft overshooting the runway occur frequently. The statistical data of the past decade shows that the number of aircraft overrunning the end of the runway is increasing year by year, which has already posed a serious threat to the safety of aircraft and passengers. The International Civil Aviation Organization stipulates that a 300m runway end safety zone must be set. However, many airports cannot extend the runway due to the limitations o...

Problems solved by technology

Traditional corrugated sandwich panels mainly include triangular corrugated panels, trapezoidal corrugated panels, and sinusoidal corrugated panels. However, these sandwich panels cannot meet the energy absorption requirements of airway surface arrest and have typical anisotropic properties.
