Abstract

Results are presented from low-speed windtunnel testson an isolated generic chined forebody withpneumatic methods of yaw control at high alpha.Measurements of forces and moments were made on theforebody at angles of attack in the range 0° ≤ ɑ ≤60°. Slot blowing through the chine edge at variousangles and upper surface tangential blowing havebeen compared, and optimum configurations have beenidentified. The effects of forebody cross-sectionalshape have also been investigated and have beenfound to be highly critical in determining blowingeffectiveness. Limited flowfield visualisation isalso presented in order to gain some understandingof the flow field characteristics.
