Abstract

An MEMS weapon security apparatus includes a monocrystalline silicon substrate, the monocrystalline silicon substrate is sequentially provided with a silicon dioxide insulation layer and a monocrystalline silicon structure layer, the monocrystalline silicon substrate is also provided with a circular acceleration bore hole, and a bayonet pin mechanism, a pawl mechanism and a separation mechanism are made in the monocrystalline silicon structure layer, wherein the movable bayonet pin in the bayonet pin mechanism, the pawl in the pawl mechanism and the explosion-proof separation plate in the separation mechanism are engaged through a tooth-shaped structure, the explosion-proof separation plate shields the acceleration bore hole and is connected with the monocrystalline silicon structure layer through an S-shaped silicon spring, a flyer hole and the acceleration bore hole are arranged in an offset manner, the bayonet pin mechanism and the pawl mechanism are respectively driven by a thermoelectric effect, a V-shaped thermoelectric executor generates certain thermal deformation under a corresponding work voltage, and a lever amplifies the thermal deformation and uses the amplified thermal deformation to drive the bayonet pin and the pawl to complete corresponding actions. The MEMS weapon security apparatus has the advantages of low cost, high intelligence and easy integration.

Description

technical field [0001] The invention relates to the technical field of fuzes, in particular to a MEMS weapon security device. Background technique [0002] The fuze is a control device (system) that uses target and environmental information to detonate or ignite the charge of the ammunition warhead under predetermined conditions. It is usually installed on rockets, missile warheads, and gun / tank / mortar ammunition, etc., according to the type of ammunition Different fuzes are selected according to different targets and the needs of dealing with targets. The fuze is an important part of the weapon system. It detects the environment and targets to obtain information, process and identify information, and realizes the safety state control and optimal detonation control of the fuze. The basic functions of the fuze are "safety" and "reliable detonation of the warhead". The safety device in the fuze is an important part of the fuze system. One of its basic functions is to prevent...
