This numerical study is about the alleviation of the Phantom Yaw Effect on a pitching missile. A pair of slit shaped side jets, so called aerostrakes is used to force a symmetric separation at the shoulder of the missile. The unsteady Reynolds averaged Navier-Stokes equation are solved with a two equation turbulence model for a case with and without applied aerostrakes. The missile is pitching sinusoidally at a frequency of 5 Hz between 0° ≤ α ≤ 44 °at Mach 0.8. The results Show that the magnitude of the side force, resulting from Phantom Yaw, is reduced by the aerostrakes and the onset angle for the PYE is shifted to higher angle of attack. A reversal of sign of both the side force an yawing monemt is also prevented when using the aerostrakes. Furthermore, the influence of the pitching motion on the relevant aerodynamic coefficients is less profound in the case with aerostrakes.
