Abstract

The invention relates to a locking type MOEMS fuse safety mechanism. The locking type MOEMS fuse safety mechanism is formed by performing processing on an SOI substrate through the integrated design scheme that a direct coupling type optical fiber optical path, a V-type electric heating driver, a spring-shuttle structure, a recoverable locking mechanism and a U-type electric heating driver are combined. The direct coupling type optical fiber optical path comprises an energy input optical fiber and an energy output optical fiber which are matched up and down. The V-type electric heating driverand the spring-shuttle structure jointly act to drive the energy input optical fiber and the energy output optical fiber to realize dislocation and alignment, so that the working and non-working statuses of the optical fiber optical path are controlled. By means of the locking type MOEMS fuse safety mechanism, the safety of status control of the fuse safety mechanism is improved, the ability of the fuse safety mechanism to resist strong electromagnetic interference inside and outside a fuse is enhanced, the function integration level of the fuse safety mechanism under the micro volume condition becomes better, and the intelligence and flexibility level of the fuse are improved.

Description

technical field [0001] The invention relates to the technical field of fuze safety systems, in particular to a locking type MOEMS fuze safety mechanism. Background technique [0002] Fuze is known as the "brain" of ammunition. Its insurance mechanism is used to ensure the safety of ammunition during normal service handling and use, and release the insurance under predetermined conditions to make the ammunition ready to fire. It is the core of ensuring the safety of ammunition. part. With the development of ammunition weapon systems, many higher requirements are put forward for fuze technology, such as miniaturization, intelligence and dexterity, etc., so that electronic logic devices and circuits are widely used in fuze insurance mechanisms. Under the conditions of modern combat mode, with the extensive use of various electronic equipment, as well as various high-power electromagnetic pulse weapons and electromagnetic cyberspace countermeasure systems used by the warring pa...
