The invention discloses a testing method for the components of
combustion gas of
gunpowder. The method can quantitatively test the
mass of main gas components in a
combustion product of the
gunpowder under specific conditions. The method mainly comprises the following steps: 1, treating of a to-be-tested sample and adjusting the initial conditions of an enclosed
combustion chamber; 2, igniting the to-be-tested sample and allowing gas produced after combustion to be fully mixed with filling gas; 3, subjecting the obtained gas mixture to
pressure reduction and flow velocity adjustment, then allowing the gas mixture to pass through a
sensor array, and acquiring related data including the pressure intensity of the
combustion chamber, the concentrations of the gas components, flow velocity, etc.; 4, treating
exhaust gas after completion of testing; 5,
processing testing data and calculating the
mass of the components of combustion gas produced by combustion of the to-be-tested sample per
unit mass; and 6, characterizing testing results. The method provided by the invention is applicable to testing of the
mass of a plurality of gas components like CO, CO2, NO, NO2, HCl and NH3 in the combustion product. The method provides a necessary technical means for research on the combustion mechanism, formula and
process design of
gunpowder.
