Detonator comprising a nonlinear transmission line
| DWPI Title: Detonator for explosives system, has nonlinear transmission line that receives input voltage pulse and compresses input voltage pulse to generate trigger signal, and igniter ignites explosive responsive to receiving trigger signal |
| Abstract: Detonators are described herein. In a general embodiment, the detonator includes a nonlinear transmission line that has a variable capacitance. Capacitance of the nonlinear transmission line is a function of voltage on the nonlinear transmission line. The nonlinear transmission line receives a voltage pulse from a voltage source and compresses the voltage pulse to generate a trigger signal. Compressing the voltage pulse includes increasing amplitude of the voltage pulse and decreasing length of the voltage pulse in time. An igniter receives the trigger signal and detonates an explosive responsive to receipt of the trigger signal. |
| Use: Detonator for explosives system. |
| Advantage: The timing of detonation of explosives is precise to ensure safety of explosives operators and minimize damage to other structures. The compression of input voltage pulse to generate trigger signal comprises increasing amplitude of input voltage pulse and increasing velocity of input voltage pulse, so as to decrease length of pulse in time. The variable capacitor operates similar to that of variable capacitor for predefined voltages, so as to reduce overall capacitance of variable capacitor. |
| Novelty: The detonator has a nonlinear transmission line (106) that is provided with a capacitance which is varied as a function of voltage on nonlinear transmission line. The nonlinear transmission line is configured to receive an input voltage pulse (202) and compress the input voltage pulse to generate a trigger signal (204) with predefined rise time and shape. An igniter (108) is provided to ignite an explosive (104) responsive to receiving trigger signal from nonlinear transmission line. The igniter is one of fuse or bridge wire. |
