Lateral Jet Interaction on a Revolution Body in Supersonic Flow

The lateral jet interaction on a slender body with rudders in supersonic flow had been investigated by numerical simulation, when the lateral jet is not in the longitudinal symmetry plane. The Surface and space flow features of jet interaction flowfield with different angles of attack was analyzed. As a result, the jet interaction destroys pressure distributions of the slender body, and causes normal and lateral loads. With angle of attack, the pressure distributions of the after body and rudders surfaces are change tempestuously, the lateral load occurs positive interaction and negative interaction. The results show that the far-field interference played a major role in the lateral jet interaction. Besides, the force/moment amplification factors present highly nonlinear with angle of attack.
