ABSTRACT:
A fluid vectoring nozzle comprises flow vectoring means suitable for selectively producing a fluid dynamic throat in the nozzle in a plane oblique to the axis of the nozzle, such that in operation fluid flow passing through the throat is rotated about an axis parallel to and coincident with the plane of the throat. That is to say, the present invention comprises flow vectoring means suitable for selectively producing a fluid dynamic throat in the nozzle in a plane oblique to the axis of the nozzle, such that, in operation, fluid passing through the fluid dynamic throat is turned towards an angle perpendicular to the plane of the throat. Fluid injection means are provided to inject a control fluid into the nozzle through a perforate region provided in at least one nozzle wall, thereby generating a fluid dynamic restriction which initiates the formation of the fluid dynamic throat.
