Abstract

Gas launchers are an important part of impact testing apparatus which have many applications in material parameters identification. Some experiments call for very high velocity which is beyond the limit of one-stage gas launchers; thus, two-stage gas launchers are employed. Several parameters affect the operation of such launchers. For optimum adjustment of such parameters, modeling and SIMULATION is necessary and inevitable. To this end, in this paper, a one dimensional model for a TWO-STAGE LIGHT GAS LAUNCHER is proposed and utilized for performance OPTIMIZATION. To simulate combustion, experimental data for burning rate has been used. The proposed model is verified by comparing its predictions with the available experimental data. It is shown that the proposed model is accurate enough to predict the TWO-STAGE LIGHT GAS LAUNCHER performance. The results of one dimensional model can be used in the basic design of the launcher to investigate the feasibility of manufacturing and estimate the costs.Moreover, the model is used to optimize the launcher performance as well as to determine optimum parameters. The statistical method of response surface is employed to find suitable second order polynomial models to predict the projectile velocity and maximum base pressure. The presented models are used to maximize the projectile velocity as well as to minimize the maximum projectile base pressure. To this end, Simplex method is employed to minimize the maximum base pressure in different conditions. Finally, the table of optimum conditions is presented to simplify the optimum use of the TWO-STAGE LIGHT GAS LAUNCHER.
