Gunpowder combustion gas component test apparatus

Abstract

The invention discloses a gunpowder combustion gas component test apparatus. The apparatus comprises a closed combustion chamber, an igniting controller, a pressure and temperature adjusting device, a flow control device, a sensor array, a data acquisition and analysis device, a standard gas cylinder array and a water bath constant temperature device. The apparatus solves the problems of difficult collection of a gunpowder combustion generation gas, and tedious steps and low automatic degree of multiple gas components. The apparatus can accurately adjust the initial state of gunpowder combustion, automatically collects the gas and tests the concentrations of the multiple gas components in a gunpowder combustion product, so the apparatus is suitable for testing the concentrations of the multiple gas components in the combustion product of solid propellants and propellant powder at a specific initial temperature under an initial pressure, and is of great significance to research the gunpowder combustion mechanism and the formula and technological design of the propellants and the propellant powder.

Description

technical field [0001] The invention relates to a propellant combustion gas component testing device, which is suitable for testing the concentration of various gas components in solid propellants and propellants in combustion products under specific initial temperature and initial pressure conditions. Background technique [0002] The combustion of gunpowder is a complex physical and chemical change process. In the combustion products, not only smoke, but also CO, CO 2 , NO, NO 2 , HCL and other gas phase combustion products. Composition detection of gunpowder gas is one of the diagnostic techniques of combustion experiments. It provides the necessary information for further understanding of chemical reaction processes and their complex interactions with fluid mechanics, heat transfer, and other physical phenomena. With the development of high-tech weapons, there is an increasing demand for clean gas generating agents, and the requirements for low characteristic signals ...

AI Technical Summary

Problems solved by technology

Among them, the electrochemical sensor has high test accuracy, but the response time is generally long, and it is impossible to test the transient gas composition and characterize the rapid change process of the gas composition.

The test device based on the principle of infrared spectroscopy and light scattering, the sensor has a fast response speed, but is also easily interfered by stray light in the environment, and the accuracy is poor
