N2 - Use gas-driven light gas gun is one of the techniques extensively used to achieve hypervelocity projectiles. The device was made up of a compressed gas gun as the first-stage drive. A new type high pressure pneumatic injecting system of gas-driven light gas gun for hypervelocity launching is introduced. As a critical component of the injecting system, the high pressure pneumatic valve was designed. Functions of the pneumatic valve were preserved and relevant techniques were discussed. Besides, a high pressure pneumatic mass flow control test-bed using inert medium was built in order to study the dynamic response characteristic of high pressure pneumatic valve in gas-driven light gas gun. To ascertain the response delay time of the valve, several turn-on and turn-off experimental tests of the valve were initiated. The results suggest that: the pressure of pneumatic electromagnetic valve gas supply circuit seriously influenced the properties of high pressure pneumatic valve; the mean delay time of the high pressure pneumatic valve was 190ms approximately at 6.5MPa gas pressure of the pneumatic electromagnetic valve gas supply circuit.
