Recoverable MOEMS safety and arming device based on optical logic control

Abstract

The invention discloses a recoverable MOEMS safety and arming device based on optical logic control. The recoverable MOEMS safety and arming device comprises a base, a supporting anchor point, a direct coupling type optical fiber optical path, an optical path gating driving unit, an active latch mechanism, a reverse locking mechanism and a limiting anchor point. The direct coupling type optical fiber optical path comprises an input optical fiber and an output optical fiber which are used for transmitting laser energy. The optical path gating driving unit is formed by combining two U-shaped electric heating drivers and is used for driving an incident optical fiber to move. The reverse locking mechanism and the active latch mechanism are both composed of the U-shaped electric heating drivers and can be controlled by two kinds of environment information respectively, wherein the reverse locking mechanism locks the optical fiber, the active latch mechanism locks the optical path gating driving unit, and double insurance is achieved. According to the recoverable MOEMS safety and arming device, laser is adopted as a carrier for ignition energy transmission, the on-off logic of the optical path is controlled through a mechanical structure, the recoverable and power-off maintaining functions are achieved, and the anti-interference capability and the dexterity level of a fuse system are improved.

Description

technical field [0001] The invention belongs to the technical field of fuze safety systems, in particular to a recoverable MOEMS safety and disarming device based on optical logic control. Background technique [0002] With the progress of weapons and ammunition systems and electronic technology, fuze safety insurance systems are also developing in the direction of miniaturization and intelligence. This makes some circuits and electronic components that can perform logic functions widely used in fuze security systems, making the all-electronic security system vulnerable to electromagnetic interference, causing failures in the fuze system, and reducing the safety of the in-line explosive sequence ammunition weapon system and reliability. Therefore, by integrating optical fiber and optical energy conversion technology into the electronic security system, using the laser as the carrier of ignition energy transmission, and the optical fiber as the transmission medium of the las...
