METHOD FOR CONTROLLING PYRO DEVICE BLASTING Russian patent published in 2016 - IPC F42D1/05 G08B17/06 

FIELD: rocket construction.

SUBSTANCE: method for controlling pyro device blasting relates to electronic automation devices and can be widely used in rocket-and-space equipment (RSE), and when performing different types of blasting operations in national economy. In RSE pyro devices are used as actuators when starting the engines, separating ship compartments, opening antennae and other elements. Essence of the method consists in that during preparation for blasting group of pyro devices, blasting circuit parameters is measured and, according to the results of measurements, each capacitor in the blasting control circuit of the appropriate pyro device is charged to voltage, providing the same current pulse in the blasting circuit for all pyro devices.

EFFECT: technical result is effective controlling the pyro device blasting control circuit state and guaranteed simultaneous blasting the group pyro devices, as well as reduced requirements to spread of parameters of blasting circuits and to characteristics of the power supply to provide blasting.
