Abstract

1421153 Deflecting propulsion jets ROLLSROYCE (1971) Ltd 22 March 1973 [25 March 1972] 14112/72 Heading B7G A ducted fan gas turbine engine has a fan (not shown) positioned at the front end of an annular duct 7 formed between the outer casing 6 of a core engine and an outer cowl 8, the cowl 8 comprising a fixed upstream portion 17 and a translatable downstream portion 18. A cascade of flow deflecting vanes 20 is connected to the upstream portion and is masked, in the position shown in Fig. 2, by the downstream portion 18 which is sealed at 28 to the upstream portion. The downstream end of portion 18 terminates in a ring of flaps 14 pivoted thereto, each flap being pivotally connected at its midpoint to one end of a link 16, pivoted at its other end to casing 6. Screw jacks 32, one for each flap, are operated by a single motor 34 and each jack carries a traveller nut 38 secured to portion 18. In operation, in the initial position shown in Fig. 2 the flaps 14 are in the normal cruise position. For take-off or landing the jack 32 is operated to translate portion 18 downstream to a position in which flaps 14 are substantially parallel to the engine axis and for thrust reversal the portion 18 is moved fully downstream causing flaps 14 to seat on casing 6 to close the aft end of the duct and vanes 20 are fully exposed thereby permitting the forward flow of air. In a further embodiment (Fig. 6, not shown) the radially inner ends of the links 16 are each mounted on an adjustable pivot to enable the flaps 14 to be moved without translation of portion 14.
