AI Technical Summary

Technical Problem

In existing technologies, it is difficult for fuses in UAV munitions to effectively switch to ready-to-fire or safe states under different environments, especially in impact environments such as transportation and drops, where it is difficult to keep the axis of the electric detonator and the detonating cord isolated.

Method used

The pin-pulling transmission mechanism, which connects an asynchronous motor and a microcontroller control system, ensures that the fuse remains isolated in different environments by controlling the isolation slider component to be in the explosion-proof safe position. The microcontroller MCM32F103C8T6 outputs a PWM signal to control the asynchronous motor to drive the isolation slider, thereby achieving the misalignment or alignment of the electric detonator and the detonating cord axis.

Benefits of technology

It achieves stable switching of the fuse in different environments, ensuring the safety of the fuse under impacts such as transportation and drops, avoiding accidental firing, and improving the safety of UAV munitions.
