In order to obtain fin cant angel of spinning projectile at equilibrium spin rate, in this paper the theory was introduced and the method how to simulate it was given. First of all, a fin cant angel was supposed, then we built model, divided air zones and generated mesh, calculated with multiple reference frame in ANSYS-FLUENT. According to calculation result, fin cant angel could be calculated, and then the same method was used for checking whether it was at rolling balance. The results show that the simulation method is feasible; the spinning projectile is at rolling balance with calculated fin cant angel, the design goal is achieved.
