Considering the transitory character of its operation, the linear induction launcher has dynamic performances such as the propulsion force and the projectile velocity which are significantly dependent not only on its geometrical dimensions but also on its feeding. In this paper, the effect of the latter, which is undoubtedly of capital importance, on the performances of the device is studied thanks to a model obtained by an analytical method called the coupled circuits method which we implemented. Our study related to two different prototypes. The first is a low speed laboratory prototype which comprises only one section of inductive reels and which was used to us as practical model on which tests were carried out for the validation of the adopted method. Let us note that the results obtained with these tests are given in this present paper. As for the second prototype, of which the geometrical data are fixed by holding account of the study undertaken on the first prototype, it comprises two sections of inductive reels. It is used as model of simulation in order to meter in obviousness the influence of the mode of feeding on the dynamic behavior of the projectile during its evolution within the sections of the launcher and at the time of its transition from the first section to the second section.
