Embodiment 1

[0025] Such as figure 1 The aircraft windshield shown in this embodiment includes a transparent composite panel element 100 and an edge connector 200, wherein the edge connector 200 is installed outside the edge of the transparent composite panel element 100 and covers the transparent composite panel element 100 The two outer surfaces of the area near the edges. The transparent composite panel element 100 comprises at least two first transparent layers 101 , at least one second transparent layer 102 and at least two annular reinforcement layers 103 . A second transparent layer 102 is bonded between two adjacent first transparent layers 101 , and a ring-shaped reinforcing layer 103 is bonded to two surface areas near the edges of at least one first transparent layer 101 .

[0026] In this embodiment, the edge connector 200 is installed outside the edge of the transparent composite panel element 100, and is fixedly connected with the supporting window frame 300 of the aircraft ...

Embodiment 2

[0058] Such as figure 2 As shown in the aircraft windshield, the aircraft windshield in this embodiment includes a transparent composite panel element 100 and an edge connector 200, wherein the transparent composite panel element 100 includes at least two first transparent layers 101 and at least one second transparent layer 102 , a third transparent layer 104 and at least two annular reinforcing layers 103 . A second transparent layer 102 is bonded between two adjacent first transparent layers 101 , and a ring-shaped reinforcing layer 103 is bonded to two surface areas near the edges of at least one first transparent layer 101 . One surface of a first transparent layer 101 is the first outer surface of the transparent composite panel element 100 . Two surfaces of a second transparent layer 102 are respectively bonded with a third transparent layer 104 and a first transparent layer 101 , and one surface of the third transparent layer 104 is the second outer surface of the tr...

Embodiment 3

[0077] Such as image 3 and Figure 4 The shown aircraft windshield comprises a transparent composite panel element 100 and an edge connector 200, wherein the transparent composite panel element 100 comprises at least two first transparent layers 101, at least one second transparent layer 102, and a third transparent layer 104 And at least two ring-shaped reinforcing layers 103; the material of the middle area of ​​the first transparent layer 101 is different from that of the edge area, and a second transparent layer 102 is bonded between two adjacent first transparent layers 101, and at least one of the first transparent layers 101 Two surfaces of a transparent layer 101 close to the edge region are respectively bonded with an annular reinforcing layer 103; a surface of a first transparent layer 101 is the first outer surface of the transparent composite plate element 100; a second transparent layer 102 A third transparent layer 104 and a first transparent layer 101 are bond...

Abstract

The embodiment of the invention provides an airplane windscreen. The airplane windscreen comprises a transparent composite board element and an edge connecting piece, and the edge connecting piece isinstalled outside the edge of the transparent composite board element and covers the areas, close to the edge, of the two outer surfaces of the transparent composite board element. The transparent composite board element comprises at least two first transparent layers, at least one second transparent layer and at least two annular reinforcing layers, one second transparent layer is bonded betweenevery two adjacent first transparent layers, and two annular reinforcing layers are bonded to the two surface areas, close to the edge, of at least one first transparent layer respectively. When the first transparent layers are broken, fragments of the first transparent layers in the middle area adhere to the second transparent layers, and fragments of the first transparent layers in the edge areacan be fixed and protected through the annular reinforcing layers, so that the integrity of the airplane windscreen is kept, then the frame disengaging time of the airplane windscreen is delayed, andsufficient time is provided for height reduction, cabin pressure reduction and emergency landing preparation of an airplane.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of aircraft, in particular to an aircraft windshield. Background technique [0002] Aircraft windshields are fail-safe with multi-layer transparent sheets and organic transparencies. During the flight, the windshield of the aircraft is subjected to the pressure difference between the inside and the outside, and there is a certain degree of deformation. If one layer of the transparent sheet is cracked, it will shatter into many small pieces under the action of the pressure difference, but the organic transparent film can connect the pieces together, and as long as the remaining transparent sheet remains intact, the aircraft windshield is still safe. [0003] However, when the transparent panels of the aircraft windshield are all broken, they are initially squeezed together by the volume increase generated by the cracks, and then they can only rely on the bonding effect of the organic tr...
