ABSTRACT:
A vectorable nozzle 17 comprising a fixed first duct 21 a rotatable second duct 22 scarfed at its rear end and a rotatable third duct 23 scarfed at its front end. The second and third ducts 22,23 are mounted in bearings 24,26 respectively and the bearing 26 is constrained to swing bodily about trunnions 29, the axis of which lies transverse to the ducts 22,23, and a screw jack 32 is provided to rotate the bearing 26 about the trunnions 29. The second and third ducts 22,23 are provided with means to rotate them in opposite directions in synchronism with the rotation of the bearing 26 in the trunnion 29. The nozzle is provided with external fairings 46,47 to provide aerodynamic streamlining when the nozzle 17 is directed rearwards. The fairings are constrained against axial and radial displacement by rollers 48 and grooves 50 at one of their ends. The fairings 46,47 are connected to their respective ducts 22,23 by members 51 so that the fairings rotate with the ducts 22,23.
