FIELD: glass.
SUBSTANCE: proposed invention relates to electrically heated armoured glass and can be used in ground, swimming, flying equipment, as well as protective glasses for optical observation devices of unmanned aerial vehicles. Electrically heated armoured glass of a vehicle has in its composition multilayer borosilicate glasses based on silicon oxides SiO2 and boron B2O3 containing oxides of alkali and alkali-earth metals, connected by transparent polymer films, and contains built-in electric conductors, mounting frame along perimeter, conductors are made in the form of multilayer insulated strips of electroconductive transparent films of non-stoichiometric tin oxides with excess content of tin atoms, besides, it comprises common electrical current collector of strips, individual current leads of strips, microprocessor for controlling the currents of the strips is connected to the current leads. Electric power terminals are connected to common electric current collector and to microprocessor. Microsystem sensors of illumination, humidity and temperature are located on the surface of the glass and are connected to the control inputs of the microprocessor.
EFFECT: high strength of armoured glass by reducing the temperature gradient and mechanical stress at the “conductor-glass” boundaries.
