无控火箭多路时序控制点火系统研究

Multichannel sequential control system for ignition of free-flight rocket

为适应新型增雨防雹火箭需要,在原单一电子延时点火机构的基础上进行了电路改进,设计了功耗小、电压低、可同时提供多个时序的电子延时装置,满足了多次点火要求。该装置已经过飞行前的各种地面试验的考核。

In order to meet the need of a new type rainfallenhancement and hailsuppression rocket,a multichannel electronic delay device with low power consumption and low voltage has been designed based on the singlechannel delay device.It meets the requirement of multipleignition.The device has been examined by a variety of ground tests of preflight.
