Device for attachment of an aircraft windshield.The device comprises a monoblock flange (14). The flange is fixed to the structure (12) of the aircraft by screws (16), so as to trap a peripheral edge of the windshield glass (10) between the flange and the structure. A dry monoblock seal (18) surrounds the peripheral edge of the windshield, such that the seal alone provides leak tightness between the inside and the outside of the aircraft. Preferably, the screws (16) are in contact with the flange (14) through plane surfaces perpendicular to the center lines of the screws. At least one second dry monoblock seal (20) may also be placed between the flange (14) and the structure (12).

1. Device for attachment of a windshield glass having a peripheral edge, an inner face and an outer face, onto an aircraft structure forming a frame having an outwardly facing face, said device comprising:a monoblock flange adapted to be fixed on said outwardly facing face of said frame, said monoblock flange having an outwardly facing surface; a plurality of screws capable of fixing the monoblock flange onto said frame, each said screw having an axis and a head facing outwardly and provided with an inwardly facing plane surface adapted to be in tightening contact with said outwardly facing surface of the monoblock flange, said inwardly facing plane surface being orthogonal to the axis of said screws; a first dry monoblock seal adapted to be mounted on said peripheral edge of the windshield glass, such that the first dry monoblock seal entirely surrounds said peripheral edge, whereby when the monoblock flange is fixed on the frame by said screws, the first dry monoblock seal is compressed both between the inner face of the windshield glass and the frame and between the outer face of the windshield glass and the monoblock flange around the entire periphery of the windshield glass, such that said first dry monoblock seal alone provides a leak tightness between the inside and the outside of the aircraft. 2. Device according to claim 1, in which at least one second dry monoblock seal is housed in a groove formed in a face of the monoblock flange facing the structure or conversely such that the second monoblock seal alone provides leak tightness between the monoblock flange and said structure.3. Device according to claim 2, in which the second dry monoblock seal is generally plane, so that each of the screws passes through it.4. Device according to claim 3, in which the second dry monoblock seal, which is generally plane, comprises annular swellings that surround each screw, to be in contact with the screws.5. Device according to claim 1, in which the heads of the screws are housed in recesses formed in the outwardly facing surface of the monoblock flange, so that they do not project on said outwardly facing surface.6. Device according to claim 5, in which each of the recesses is closed by a cap piece that is flush with said outwardly facing surface the monoblock flange.7. Device according to claim 6, in which a hole passed through each of the cap pieces.8. Device according to claim 6, in which each of the cap pieces is fixed in the recess of the monoblock flange in a tight fit.9. Device according to claim 5, in which the recesses are covered by respective sections which form at least part of said outwardly facing surface of the monoblock flange.10. Device according to claim 5, in which the heads of the screws are covered by a substance that limits penetration of moisture.11. Device according to claim 2, in which the first dry monoblock seal comprises striations on a face of this first dry monoblock seal facing towards the outside of the aircraft and in contact with the said monoblock flange.12. Device according to claim 2, in which a third annular shaped dry seal is placed between the monoblock flange and the structure around each of the screws.13. Device according to claim 1, in which at least one other dry monoblock seal is installed on a peripheral edge of the monoblock flange facing towards the outside of the windshield glass.
