Propellant container mechanical environment test safety protection method

Abstract

The invention belongs to the dangerous material mechanical environment test safety protection technical field, and concretely relates to a propellant container mechanical environment test safety protection method. The method comprises test risk analysis, test safety protective measures and safe operation requirements in a test process, and performs protective work on the aspects of active protection (explosion protection) and passive protection (explosion resistance). Active protection is mainly reflected in electrostatic protection, fire protection, lightning protection and operating personnel work standard enhancement; passive protection is mainly reflected in test site infrastructures, remote control, station site selection control and test flow arrangement. The method is suitable for a propellant container mechanical environment test employing a real propellant, and can obtain more accurate examination results, directly perform test run performance examination after the mechanical environment test, and solve the safety risks of container leakage and fracture under the recombination action of dynamic stress and internal pressure in the mechanical environment test.

Description

technical field [0001] The invention belongs to the technical field of safety protection for mechanical environment tests of dangerous goods, and in particular relates to a safety protection method for mechanical environment tests of propellant containers. Background technique [0002] Liquid propellant is a substance that enters the rocket engine in a liquid state, undergoes chemical reactions and thermodynamic changes, and provides energy and working fluid for the propulsion system. When performing vibration tests on liquid propellant containers in the laboratory, the primary consideration is the safety of the test medium. The safety performance of liquid propellant mainly refers to its fire, explosion hazard and toxicity. Liquid propellants will not ignite and explode under normal conditions, and can only cause fire and explosion under certain external conditions. These external conditions include: heat, open flame or electric spark, mechanical action, shock wave, radiat...

AI Technical Summary

Problems solved by technology

Because the mechanical environment test of the propellant container has certain risks, the container may leak and rupture under the combined action of dynamic stress and internal pressure in the mechanical environment test, resulting in the leakage of propellant and posing a threat to personnel and equipment
