Description

technical field [0001] The invention relates to the safety technology of the fuze, in particular to a MEMS electromagnetic energy channeling device applied to the fuze and a preparation method thereof. Background technique [0002] In order to ensure the safety and reliability of the fuze function in various missiles, the fuze safety system has been developed rapidly. During the use of various types of ammunition at this stage, the fuze inevitably faces interference from various environments. For example, in the service processing stage, the pyrotechnics of the fuze system are susceptible to interference from static electricity and electromagnetic pulses, and false triggering occurs. Causing casualties and property damage; during the launch of ammunition and the entire trajectory, the fuze control system and the entire detonation sequence are susceptible to interference from the external environment or the enemy (static, constant current, strong electromagnetic pulse), such ...

Problems solved by technology

This surge voltage (current) contains very large energy, if it enters the equipment, it will not only cause interference, but also cause serious damage to the devices, components and circuits in the equipment, so measures must be taken to prevent the impact of the surge

In order to solve this kind of problem, the traditional fuze system generally uses shielding to isolate electromagnetic interference. However, due to the large size of the shielding layer and the shield, and the miniaturization of the fuze system, the traditional method is no longer used; in the face of constant current, static electricity Interference, set TVS (transient voltage suppression diode) at both ends of the control terminal or pyrotechnics, which can effectively absorb static electricity and constant current energy, and instantly discharge a large amount of current to achieve energy dredging

However, due to the impedance matching problem of the TVS tube itself, its energy absorption performance is limited.
