Title Light Gas Emission Device Interior
Ballistic Characteristic Research
Abstract
Two stage light gas gun is a kind of high temperature low molecular weight
gas refrigerant expansion way to propel the projectile，to obtain high
velocity of projectile launching system. To study the interior ballistic
process, discussed the emission parameters on the emission performance of.
Using classical interior ballistic theory to describe the drug indoor
combustion condition and the piston motion process, the isentropic
compression mathematical model to describe the light gas indoor gas flow
state, combined with the projectile force to establish a complete
mathematical model of transmitting part. And through the piston motion
state of the combination of the two, establish two stage light gas gun
process mathematical model. Based on the classical Rung-Kuntta method for
solving an equation, realizing two stage light gas gun firing process
numerical simulation. Through the establishment of the mathematical model,
the use of numerical methods for solving, realizing two stage light gas
gun firing process calculation, in the Φ100 /30 two stage light gas
gun for the basic model, in its analysis of the variety of different
structure parameters and loading conditions of the interior ballistic
characteristics. Summarize the structure parameters and loading
conditions on the two stage light gas gun behaviors.
