Improvements in the electromechanical conversion of energy using shock waves; Contribution a la conversion d'energie electromecanique par onde de choc

Abstract

This report concerns the electrical mechanical conversion. In this study it was obtained by the depolarization of a ferroelectric ceramic. We are particularly interested by the high electrical horse-power. Shock wave which produces depolarization is created by a gun powder. The speed of the projectile is measured and the pressures generated in the ceramic is determined graphically. The energy freed is released on a linear resistive load. We were able to prove by different parameters how to obtain the maximum electrical energy. On a resistive load of 26 ohms, it was freed 0,91 J/cm{sup 3} in less than 0,5 μs corresponding to an electrical horse-power superior to 2 MW/cm{sup 3}.
