System for safety detection of working reliability of mortar projectile series fuze

Abstract

The invention relates to a system for safety detection of working reliability of a mortar projectile series fuze, belonging to the technical field of fuze performance test devices. The system comprises a linear inertia safety analog liberation subsystem for releasing a fuze back seat safety mechanism, and a turbine safety fuze blowing detonation subsystem for releasing a fuze turbine safety mechanism and striking to detonate the fuze. By using the system provided by the invention, the static simulation of the environmental force on the fuze during live firing can be simulated in a test room, so that the basic judgment of the safety release action reliability and ignition reliability of a tested fuze can be finished, and a live firing test can be partially replaced.

Description

technical field [0001] The invention relates to the technical field of fuze performance testing devices, in particular to a system for detecting the reliability and safety of fuzes of a series of forced bombs. Background technique [0002] The fuze is a system that controls the timely explosion of the ammunition explosion sequence by sensing target information or according to predetermined conditions. Simply put, the fuze is a device that controls the detonation of the projectile under the most favorable conditions relative to the target. Fuzes can be divided into different types according to different principles of action. The invention is mainly used to complete the test of the mechanical trigger fuze of the turbo mechanism used for the mortar shell. This type of fuze adopts a dual-environment force redundant double-safety structure composed of a recoil safety mechanism and a turbine safety mechanism, and relies on the fuze firing pin to fire the detonator when hitting th...

AI Technical Summary

Problems solved by technology

The blowing and detonation in the prior art are respectively completed by two independent devices, and the functions are relatively single

During the test, the fuze that has completed the blowing test needs to be moved from the blowing device to the detonating device. Since the fuze has been disarmed at this time and is in a state of being fired, moving the fuze may cause its unexpected action

Therefore, using existing equipment to carry out fuze blowing and detonation tests, the operation process is complicated and has certain dangers

[0005] At present, the reliability test of the function of this type of fuze usually adopts the method of live ammunition firing, which has certain safety risks and high test costs.
