Structural Design of an Insulated Gas Circuit Joint of Short-range Air Defense Missile

doi:10.3969/j.issn.1000-1093.2022.01.009

Abstract

Abstract: An insulated gas circuit joint is proposed to avoid the potential safety hazards brought by traditional refrigeration gas cylinders to missile-borne electronic devices. It is designed by using three-dimensional design software Solidworks.The airtightness of joint structure was simulated by using ANSYS software, and a real gas circuit joint was made for conductivity and ventilation experiments. The simulated results show that the gas circuit joint does not leak under the limit pressure, and has no electric conduction and air leakage in the electric conduction and air tightness experiments. Simulated and experimental results prove that the insulated gas circuit joint has both insulativity and air tightness, and can avoid the potential safety hazards of missile-borne air circuit.

Key words: short-rangeairdefensemissile, gascircuitjoint, threadedconnection, insulativity, airtightness
