Propellant combustion tail gas quantitatively measuring device

The invention discloses a quantitative measurement device of components of propellant powder burning tail gas, the device is characterized in that one end of a transmitting tube is connected with an electric ignition cable switch with an ignition groove; the big end of a piston is matched with the inner wall of the transmitting tube in a sliding way, while the small end of the piston is connected with a pawl arrester; an automatic control heating device and a pressure regulation device are adopted to ensure high constant temperature and stable air pressure of an air test chamber; an air outlet of the transmitting tube and an air inlet of the air test chamber are connected. When a measured propellant powder sample arranged on the ignition groove is burned, the burned gas of the propellant powder pushes the piston to move until the big end of the piston slides over the air outlet, the burned gas can enter the air test chamber; the above process truly simulates the whole process that a pill flies off a bouche fr
