DEVICE FOR MONITORING AND EXPLOSION OF EXPLOSIVE CHARGE FILAMENT Russian patent published in 2006 - IPC G08B17/06 

FIELD: rocketry and space engineering.

SUBSTANCE: proposed device is provided with power supply source, resistors, output transformer, communication line whose output is connected to explosive charge filament and switching units made on N-type field-effect transistor and on P-type field-effect transistor; gates of field-effect transistors are shunted by limiting resistor and potentiometer connected in series; gate of N-type field-effect transistor is connected through first resistor to minus of power supply source which is also connected with source of this field-effect transistor; gate of P-type field-effect transistor is connected through second resistor to plus of power supply source which is also connected with source of this field-effect transistor, drain of N-type field-effect transistor is connected through primary winding of output transformer to second output of communication line; outputs of gates of field-effect transistors perform function of input of device and secondary winding of output transformer is used as monitoring output of device.

EFFECT: enhanced reliability due to increased level of safety.
