There are several methods to control an aircraft that one of them is lateral jet. The most important feature of this method is the proper operation at low dynamic pressures. In the present study, the new arrangement of side jets is experimentally by wind tunnel testing. The tests are performed on a standard model. In present scheme, two parallel jets are used at the top and two parallel jets at the bottom of the model. By this combination, pitching and rolling channels can be controlled. In the present study, pressure distribution in upstream and downstream of jet and in the middle of jets have been analyzed. To visualize the shocks, Schlieren method has also been used. The results are presented in the subsonic and supersonic flows, at positive and negative angles of attack. Reducing the pressure in midfield jets in the same position downstream of a jet and keep the pressure area at the upstream of jets are the advantages of this method. This property beside roll control increases the attractiveness of this method.
