It conducts theoretical analysis of the single-stage reluctance coil launcher.Based on the electromagnetic field finite element computation and external circuit coupling,it studies influence of the electrical parameters,the head shape and initial trigger position of the projectile on the energy conversion efficiency of the single-stage reluctance coil launcher.The results show that the energy conversion efficiency rises with the increase of voltage and capacitance,and the best head shape and initial trigger position of the projectile can make the energy conversion efficiency optimum.
