Abstract
Focus on solving the problem of ballistic burst of a individual rockets, based on analyzing the working principle of the fuse, using the methods of simulation analysis and experimental verification,the output of the 555 timer self-destruct control circuit under the condition of unstable power supply was studied. The results show that the 555 timer will be power-off, while the turbine generator staling in the air; within the timing range, the power is supplied by an energy storage capacitor after the 555 timer power blackout in advance, the 555 timer will rapidly output the self-destruction control signal after power-off, and the voltage of output terminal increases with the time delay of the power-off. The problem of early output initiating control signal caused by the power-off of 555 timer can be solved by connecting the Zener diode regulator to the output of the 555 timer.关键词
