title = "Dynamic analysis for cryogenic and high pressure fueling valve of combustion light gas gun system",
abstract = "The paper describes the dynamic behaviors of a unique cryogenic and extra-high pressure pneumatic valve for the high pressure gaseous medium injection of combustion light gas gun (CLGG), which is known as a unique technique to achieve hypervelocity projectile. As a critical component of the CLGG's injecting system, the operation principle and dynamic property of the valve are detailedly investigated by means of theoretical and experimental way. The problem of needing large driving power and slowing response in extra-high pressure pneumatic on-off valve is solved by means of lever pneumatic force balance method. A two-stage valve that used a two-position five-port pilot solenoid plunger valve to control a large flow-rate poppet valve is developed. The definitions and rules of a dynamic processes based on the critical pressure points in the control chamber are put forward. The mathematical models of the valve are obtained based on above definitions and rules. The paper show that the valve's dynamic property obtained from the modeling and simulation is in accordance with the experiment results. The main work of this paper concentrates on investigating the operation principle, mathematical model and dynamic characteristics of the new cryogenic and high pressure fueling valve of CLGG system.",
