Numerical studies were performed for supersonic flow of M = 1.5 past a generic slender body equipped with mini-sized flow effectors on its nose cone. Three flow effector installations were studied and compared with wind tunnel data. The numerical results predicted the flow details of how the vortex systems were changed by the presence of the flow effectors, thereby affecting the lateral force performance of the configuration. In general, the numerical lateral and axial forces results were in reasonable agreement with the experimental data. The results showed that the peak side forces occurred at an angle of attack of approximately 17°, and the maximum side force occurred when the flow effector was situated on the leeward side of the body of an angular position of 225°. The numerical studies also showed that the side forces induced by the flow effectors could be on average 25% of the normal forces. This re-confirms that the concept of using small devices at the nose of the slender body to control the side forces is feasible.
