Abstract

1,255,010. Jet propulsion nozzles. ROLLS-ROYCE Ltd. May 8, 1969. [May 8, 1968], No.21864/68. Addition to 1,230, 778. Headings F1J. In a modification of the apparatus for controlling the flow of fluid through a duct, such as a jet propulsion nozzle, as described in parent Specification wherein flaps 13 are pivotally mounted at 30 to the duct 11 and controlled by piston and cylinder fluid-pressure motors 15, adjacent flaps 13 are connected by links 16 to retain the flaps substantially in circumferential alignment. The links 16 of each pair are connected by ball joints 17 at their radially outer ends to a bracket 18 forming part of one flap 13, whereas the inner ends of the links 16 are connected by ball joints 19 to brackets 20 forming parts of the adjacent flaps 13. The links 16 move from the position shown in full lines in Fig. 3 to the position shown dotted as the flaps 13 move from the fully open to the fully closed position. Triangular shaped filler members 23 seal the gaps between adjacent flaps 13. The members 23 have lips 31 slidably engaging the lower surfaces of the flaps 13 and are held in contact with the latter by bridge pieces 24 each secured to a respective member 23 by a pivot pin and having portions slidably extending over the outside of the flaps 13 between pins 27 thereon.
