Abstract:	Synchronous induction coil gun (SICG) is a new concept of kinetic energy weapon. Its operation is affected by many factors due to the complex electromagnetic environment of multi field coupling and extreme impact interaction. The coil temperature rise during electromagnetic launching has become one of the main factors limiting the firing efficiency and service life of the generator. In this paper, the single stage synchronous induction coil gun is taken as the research object. Firstly, the model based on current filament method (CFM) and the finite element “field path” coupling model are established, and the emission efficiency and influencing factors of the two models are compared and analyzed respectively. Then, the effects of different structural parameters on armature temperature rise and acceleration are studied in detail, and the matching relationship between slip and turns of high speed transmitter is clarified. The simulation results show that the acceleration can be reversed to a certain extent by using appropriate linear distribution slip, so that the acceleration process of the armature in the barrel is more stable, and the accurate control of the armature firing rate and direction is realized. The conclusion of this paper can provide reference for the structure design and efficient operation of synchronous induction coil gun.
