Description

technical field [0001] The invention relates to a fuze safety system, in particular to a micro-electromechanical combined logic device applied to fuze safety and a preparation method thereof. Background technique [0002] In order to ensure the safety and reliability of fuze functions in various types of ammunition, fuze safety systems have been developed rapidly. It mainly includes an all-mechanical fuze safety system and an all-electronic safety system. The mechanical fuze safety system has a large structural size and cannot shield the external complex electromagnetic environment, which reduces the safety performance of the fuze; the all-electronic safety system is achieved by increasing the detonation energy threshold. , to achieve security capabilities, but miniaturization is the main problem he faces. In a complex environment, the safety and reliability of the fuze system cannot be guaranteed. Security systems applied to fuzes are increasingly being miniaturized, and i...

Problems solved by technology

However, with the complex and changeable battlefield environment in future wars, it is increasingly difficult for micro-electromechanical security systems with a single function to adapt to the complex environment of the battlefield.

For example, transient electrostatic voltage pulses or transient high currents will invalidate the fuze security system with a single logic function, causing missiles to fail or explode early, greatly reducing the ability to effectively strike the enemy
