AVIATION LAMINATED GLAZING WITH MINIMAL DEFORMATION IN THE EVENT OF BREAKING OF ALL GLASS SHEETS THEREOF Russian patent published in 2022 - IPC B32B17/10 B64C1/14 

FIELD: glass.

SUBSTANCE: invention relates to laminated glazing for a vehicle or structure. The glazing comprises an internal structural glass sheet forming the inner side of the laminated glazing and having a surface compressive stress of 400 to 1,000 MPa, with an exchange depth of 100 to 500 mcm, and an external structural glass sheet with a surface compressive stress of 50 to 300 MPa with an exchange depth of 50 to 100 mcm, on condition that the product of the surface compressive stress and the exchange depth of the external structural glass sheet does not exceed 25,000 MPa·mcm, wherein the internal and external structural glass sheets have identical or different thicknesses, each within the range from 3 to 20 mm. The invention discloses an application of the above laminated glazing as glazing of a sealed aerial vehicle.

EFFECT: invention provides a combination of resistance to collision with birds, wherefor intensive reinforcement of the glass is required, and the need for resistance to pressure in the event of destruction of all layers.
