SYSTEM FOR CONTROLLING NOISE EMISSION Russian patent published in 2010 - IPC G05B15/00 F41H13/00 

FIELD: physics.

SUBSTANCE: invention discloses a system which has a logic unit which enables reception of instructions from aircraft onboard electronic equipment and generation of instructions for noise emission, and units for switching noise emission circuits. Each of the said switching units consists of an interface module, a switching module and a module for controlling the emission circuits which has a first NOR logic element, whose inputs are connected to control circuits of the switches of the switching module which are connected to noise emission circuits, and the output of the first NOR logic element is connected to the first input of a second NOR logic element, whose output is connected to the input of the interface module which is connected to the logic unit and control circuits of the switches of the switching module, the second input of the second NOR logic element is connected to the first resistor of the control module of the emission circuits and through a transistor to the second resistor of the control module of the emission circuits and an RC circuit which is connected to the resistor of the switching module designed for limiting current and acting as a shunt.

EFFECT: more efficient protection of aircraft from being struck by guided missiles.
