Wind tunnel measurements on a full-scale F/A-18 with forebody slot blowing or forebody strakesResults are presented of tests, conducted on a full-scale F/A-18 in the 120-Foot Wind Tunnel at NASA Ames Research Center, to measure the effectiveness of a 16-in.-long tangentially blown slot and of deployable strakes (measuring 4 ft in length) positioned on the aircraft's forebody. Fixed strakes with deflections of 30, 60, or 90 deg were tested to simulate the deployment of conformal actuated forebody strakes. It is shown that both the tangentially blown slot and the deployable strakes are effective in generating large yawing momemts at high angles of attack, without inducing significant coupling in the other axes.
