Description
technical field [0001] The invention belongs to the technical field of solid engine safety ignition circuits, and in particular relates to an ignition redundant solid engine ignition circuit. Background technique [0002] At present, due to the advantages of solid motors in transportation and storage, they are widely used in various rockets, guided bombs, missiles and various individual weapons. Since solid motors are explosive substances, the ignition head of solid motors is electrically sensitive. Most of the existing solid motors have safety protection design. For large solid motors, they are often designed with mistriggered flameout devices. For small solid motors, most of the methods used are to store the two ends of the ignition head of the solid motor. It is kept in a conduction state during transportation to realize protection against abnormal discharge. [0003] However, there are potential safety hazards in the existing design of safety protection circuits for sma...
