A sensitivity study for pneumatic vortex control on a chined forebodyA study was conducted to assess the sensitivity of yaw control on a chined forebody to the longitudinal location of a blowing slot at the chine edge. In addition, the effects of port blowing were also studied. NASA Langley's thin-layer Navier-Stokes code CFL3D was used to compare flow field characteristics and total yawing moment coefficients for the blowing configurations. Based upon equivalent blowing momentum coefficients, a significant increase in yaw control effectiveness was attained from the forward slot, relative to the aft slot, and port blowing was less effective than either slot blowing configuration.
