METHOD FOR DETERMINING CHARACTERISTICS OF ACTUATION OF DETONATING DEVICE Russian patent published in 2016 - IPC F42B35/00 G01P3/36 G01P3/64 C06C7/00 

FIELD: measuring equipment.

SUBSTANCE: method for determining characteristics of detonating device actuation relates to measurement equipment, and can be applied to determining characteristics of detonating device actuation that provides for initiation of explosive substance (ES) charges, particularly for determining moment of ES charge initiation by detonating device relative to moment of involve pulse supply. Knowledge of these time moments simplifies design and development of initiation systems, wherein detonating devices are included, for calculation of their gas-dynamic characteristics. Proposed method comprises supply of involve pulse and generation of detonation wave in ES charge of detonating device, which involves ES charge being initiated. Moment of involve pulse supply to detonating device and moment of detonation pulse transfer to initiated charge are determined. Recording of second moment is performed at least by one optical sensor based on fibre-optic line installed perpendicular to axis of detonating device and facing one end towards area of detonation transfer, and another end towards recording equipment. Detecting light flashes of optical radiation is performed by conversion light signal into electric one, whereof moment of transmitting detonation pulse to initiated ES charge is registered relative to moment of involve pulse supply to detonating device.

EFFECT: invention increases reliability of information during tests.
