Problems solved by technology

Traditional small-caliber ammunition safety systems mainly adopt precision machining, combined with manual and mechanical assembly to achieve system integration, but due to the presence of artificial components in the production and assembly process, the reliability of small-caliber ammunition fuzes is reduced
Unable to improve the batch degree of the system
With the development of micro-electromechanical system (MEMS) technology, a batch, miniaturized, and intelligent MEMS fuze safety system has emerged as the times require. This type of safety system can only realize the distinction between recoil overload and centrifugal overload, that is, in the order of milliseconds , to complete the fuze system's perception of recoil overload and centrifugal overload in the ballistic environment, so as to realize the alignment of the detonation sequence, but it cannot meet the long-distance disarming insurance index of the fuze
Therefore people often adopt the remote unlocking safety module of individual module, make fuze safety system meet the requirement, but such solution can't fundamentally reduce the quality, the size of fuze safety system, thus become the obstacle of fuze miniaturization

Abstract

The invention discloses a small-caliber ammunition remote arming MEMS safety system and an implementation method thereof. According to the small-caliber ammunition remote arming MEMS safety system, adelay arming device is adopted, before the safe distance of a muzzle is not reached, a fuse control system controls the delay arming device to apply the force opposite to the centrifugal overload direction to a centrifugal anti-explosion sliding block, and the centrifugal anti-explosion sliding block is controlled to not move; after the safe distance of the muzzle is determined, the delay arming device is used for relieving the force of the centrifugal anti-explosion sliding block, the centrifugal anti-explosion sliding block breaks away from restrain, and displacement is generated under the centrifugal overload action of the small-caliber ammunition, displacement is generated, and an explosion hole and initiating explosive are aligned to each other and enter an attack state. From the aspects of design and machining of the fuse, the structure size is miniaturized, the power consumption is low, and the consistency of processed samples is good; secondly, the function of remotely arming of the safety system can be realized, so that the control intelligence of the fuse safety system is realized, and the height integration of the small-caliber ammunition fuse system is improved.

Description

technical field [0001] The present invention relates to small-caliber ammunition security and release control technology, in particular to a MEMS security system for remote release of small-caliber ammunition and its implementation method. Background technique [0002] With the increasing assembly demand of small-caliber ammunition, the function of the fuze control system of small-caliber ammunition is gradually developing towards system integration and generalization. Traditional small-caliber ammunition safety systems mainly use precision machining, combined with manual and mechanical assembly to achieve system integration. However, due to the presence of artificial components in the production and assembly process, the reliability of small-caliber ammunition fuzes is reduced. Can not improve the batch degree of the system. With the development of micro-electromechanical system (MEMS) technology, a batch, miniaturized, and intelligent MEMS fuze safety system has emerged a...
