EXPERIMENTAL INVESTIGATION OF TANGENTIAL SLOT BLOWING ON A GENERIC CHINED FOREBODY

An experimental investigation of tangential slot blowing was performed on a generic chined forebody. Lowspeed measurements of lateral forces and moments were made on the forebody at high angles of attack (0 deg less than or equal to alpha less than or equal to 45 deg). Tangential slot blowing was investigated as a means of forebody flow control to generate side force and yawing moment levels capable of overcoming flo w asymmetries. The effects of jet mass now ratio and jet longitudinal position were studied. Limited flowfield visualization was also conduc ted in order to gain a better understanding of the flowfield character istics. Tangential slot blowing was found to overcome tile natural flo w asymmetry of the forebody throughout the angle-of-attack range studi ed.
