AI Technical Summary

Technical Problem

The existing cruise missile launching devices have problems such as low ejection speed, insufficient energy, complex operation, poor safety, large size, high noise, and easy to be discovered. In particular, the intermittent acceleration of the electromagnetic launching device causes the cruise missile to suffer major impact damage, and the launching device is too long and has high cost.

Method used

The magnetoresistive mover is adopted. By setting multiple soft magnets and coils in the bore tube, the coil is powered on and off with sensors to achieve continuous acceleration of the magnetoresistive mover, avoiding multiple impacts and impacts, reducing damage to the cruise missile, and shortening the launch time and device length.

Benefits of technology

It realizes the rapid, safe and convenient launch of cruise missiles, reduces the damage to cruise missiles, shortens the launch time, saves costs, and reduces noise and volume.

Abstract

The present application provides a magnetoresistive mover and a magnetoresistive cruise missile launcher. The magnetoresistive cruise missile launcher includes a barrel, a magnetoresistive mover, multiple coils, and multiple sensors. Through the arrangement of multiple soft magnets, during a launch process, the sensor detects the soft magnet multiple times, and the corresponding coil generates a constant magnetic field multiple times, applying electromagnetic attraction toward the launch end to the magnetoresistive mover multiple times, thereby shortening the launch device length and saving costs. By designing the length and distribution distance of each component, the sum of the length of the coil and the spacing length of adjacent coils is equal to the spacing length of adjacent soft magnets, which is equal to the sum of the lengths of all soft magnets. In this way, during the launch process, the magnetoresistive mover is continuously subjected to the electromagnetic attraction toward the launch end, so that the magnetoresistive mover continuously accelerates and pushes the cruise missile, avoiding multiple collisions and impacts on the cruise missile and reducing damage to the cruise missile.
