Abstract

958,307. Jet propulsion nozzles. ROLLS-ROYCE Ltd. Feb. 12, 1962, No. 5367/62. Heading F1J. A jet engine casing 14 Fig. 2, has a variable jet propulsion nozzle provided by flaps 17 controlled by a cylindrical flap control member 23, moved by rams 24 and guide members 33 . . . 36 Fig. 3 secured to the casing and the flap control member which cooperate to ensure that the flap control member moves substantially axially. A mounting ring 15 is secured to the jet pipe 14 and carries pivots 16, on each of which is mounted a flap 17 carrying a roller which is engaged by the tapered end portion 22. An axially-directed guide rail 35, secured to the flap control member is engaged by rollers 36. Ram pistons 27 are connected to the flap control member by links 30 and an extension 34, of the cylinder 2 co-operates with rollers 33 carried by brackets 31 mounted on the flap control member. Movement of the flap control member to the left in Fig. 2 causes the end portion 22 to engage roller 21, pivoting the flaps 17 to reduce the nozzle area. Movement of the flap control member to the right permits the engine gases to move the flaps outwardly.
