Abstract
The thrust director assembly may include a thrust director cone with its apex oriented into the fan airstream and a larger thrust vectoring ring concentric with the director cone. The thrust director assembly axis is angularly displaceable relative to the fan axis for modifying the geometry of the duct outlet such that the aperture of the outlet annulus is reduced on one side and simultaneously enlarged at a diametrically opposite side. The effect of the modified geometry is to increase fan thrust on the enlarged side while diminishing thrust on the narrowed side, thereby to develop a lateral thrust component acting on the airframe for providing long moment pitch and roll control.
