FIELD: testing equipment.SUBSTANCE: electric current from a DC source is supplied to an incandescence element of a pyrotechnical item, the current supply moment tand the current value I are fixed. The moment is fixed for ignition of the pyrotechnical item charge tby the moment of current surge on the element of incandescence of the pyrotechnical item, and the time is detected for initiation of the pyrotechnical item T, as the difference between the moment of ignition of the pyrotechnical item charge tand the moment of DC supply t. The device for determination of pyrotechnical item actuation characteristics consists of a breaking circuit with a source of power supply connected to an element of incandescence of a pyrotechnical item. The device includes a unit of initiation time determination. The break circuit comprises the serially connected components: a power supply source, a key for circuit closing, an element of incandescence of a pyrotechnical item, a device for measurement of current force in the breaking circuit. The output of the current force measurement device is electrically connected to the input of the initiation time determination unit. The power supply source is made in the form of a DC voltage source.EFFECT: improved reliability of tests.3 cl, 1 dwg |
