| Abstract: | The main objective in this paper is to determine the effect of some system parameters on the ballistic performance of electrothermal light gas launcher. A lumped parameter IB model of electrothermal launcher is given. The influence of the variation of the initial pressure ( p 0) , electrical energy density ( e 0) , chamber volume, diaphragm broken pressure, and characteristic of the gas on system performance is analyzed, and the resistance of arc are calculated with the experimental equation of R=R(p 0,e 0) . The parametric study shows the importance of initial pressure, chamber volume, and total electrical energy expended on gun performance, and the optimization study of the interior ballistic process for electrothermal light gas launcher are discussed also. |
