Deceleration hysterisis measuring apparatus for soft recovery system

Abstract

A deceleration hysteresis measuring apparatus for a soft recovery system is configured to transmit an electromagnetic wave to a pressure tube of the soft recovery system and receive the electromagnetic wave reflected from a projectile moving in the pressure tube so as to measure a distance of the projectile based on signals of the transmitted and received waves.

Description

CROSS REFERENCE TO RELATED APPLICATION(S)[0001]This application claims the benefit of Korean Patent Application No.10-2016-0089226, filed Jul. 14, 2016, which is hereby incorporated by reference in its entirety into this application.BACKGROUND OF THE INVENTION1. Technical Field[0002]The present disclosure relates generally to a deceleration hysteresis measuring apparatus for a soft recovery system and, more particularly, to a deceleration hysteresis measuring apparatus that is installed in a soft recovery system to measure hysteresis of deceleration in velocity of a projectile moving at high speed in the soft recovery system.2. Description of the Related Art[0003]As well known to those skilled in the art, a soft recovery system is a ballistic compression decelerator that converts kinetic energy of a high-speed projectile such as shells to thermal energy using one or more pressure tubes. A deceleration rate can be regulated with adjustment in pressure(s) within the tube(s) depending ...

AI Technical Summary

Benefits of technology

The patent text describes a soft recovery system that helps to prevent damage to a projectile during a launch. Even if the projectile gets stuck in the pressure tube, the system allows for easy maintenance and checking of the projectile's position. This helps to prolong the life of the soft recovery system and minimize downtime.

Problems solved by technology

Major components employed to a fuze sensor for mounting to a shell have to be made smaller due to a restricted design of the shell, and require a normal operation even in high shock environments such as a shell-firing environment.

However, since a system or components thereof for checking shock resistance and a conventional deceleration hysteresis measuring apparatus cannot be mounted on the same position in the test specimen projectile, there is a limit to measure in real-time deceleration hysteresis of the system or components mounted in the test specimen projectile.

Assuming the case where a test specimen projectile may often be stopped in any of pressure tubes during the recovery test if the pressures of the pressure tubes are not optimized depending on velocity and weight of the projectile, it may be difficult to check the position of the stopped projectile, since the conventional measuring apparatus only measures deceleration.

Accordingly, the recovery system cannot be repaired easily.
