The reverse roll of fixed-canards of two-dimensional trajectory correction projectiles will inevitably affect ballistic characteristics, including dynamic equilibrium angle and ballistic drift values. Characteristics analysis was presented in this paper. Assuming that fixed-canard has no pneumatic coupling with the shell, equation of the attack angle was proposed, which was suitable for all projectiles with dual spin configuration. Then analytic formulas of the dynamic equilibrium angle and ballistic drift were deduced. By studying the formula, the influence factors for the characteristics were analyzed. The conclusion shows that the overturn moment aerodynamic deviation coefficient most greatly affects the angle, and the roll velocity of the canard affects the characteristic slightly.
