Silver wire fixing support with prestress and forming method

Abstract

The invention relates to a pre-stressed silver wire fixing bracket and a forming method. The pre-stressed silver wire fixing bracket comprises a mounting base, a pre-stressed bracket, a compression screw and a silver wire, the mounting base is a combustion chamber shell front sealing head; a hole is formed in the center of the front sealing head and a threaded connection structure is designed; one end of the silver wire is fixed to the inner surface of the front end socket through a support, the other end of the silver wire is fixed to the charging tool before the propellant is poured, the charging tool is removed after the propellant is solidified, and the silver wire is in the design state parallel to the axis; before being fixed, the pre-stress support is of a plane structure and is in an internal non-pre-stress state, and after being installed in place through the compression screws, the pre-stress support deforms due to limitation of the installation base and meanwhile generates pre-stress. The support with the prestress provides tensioning force in the silver wire fixing process, and it is guaranteed that the silver wire is tensioned. According to the method, it is guaranteed that the silver wires are located on the designed distribution circle, the loosening phenomenon of the silver wires is avoided, and the problem of silver wire fixing during pouring of the adherent pouring silver wire embedded end combustion grain propellant is solved.

Description

technical field [0001] The invention relates to a silver wire fixing bracket for casting and forming a silver wire end fuel column and a forming method, and belongs to the technical field of solid rocket motor charging for tactical missiles. Background technique [0002] With the continuous improvement of the high-speed and high-acceleration requirements of tactical missiles in weapons and equipment, for the same total impulse requirements, the overall design space for solid rocket motors in the overall structural layout of the missile is getting smaller and smaller. The tactical missile not only requires the solid rocket motor to provide enough energy to increase the missile range, but also requires the missile to quickly release energy when approaching the target to meet the high acceleration requirements, improve the penetration success rate and the terminal effective overload. [0003] In order to meet the overall demand, the pulse engine scheme is more applied to the mo...

AI Technical Summary

Problems solved by technology

Due to the design requirements of the integrity of the charge structure, the internal combustion tubular charge has a relatively low filling rate, which cannot make full use of the charge space, resulting in a small amount of charge, which does not meet the high requirements of the missile for the total impact
