Abstract
The effects of attack angle on side jet aerodynamic interaction were experimentally investigated. Experiments were conducted by using the ISAS supersonic wind tunnel. A model used in this study is a 10deg half-angle blunt cone with a circular sonic jet injected at right angles to the body surface on the leeward side. Force and surface pressure measurements were performed as well as schlieren and oil flow visualizations. As a result, it is found that the aerodynamic interaction promotes the jet reaction force with increasing attack angle. Furthermore, the flowfields with aerodynamic interaction at high attack angles were clarified.
