Abstract

1388406 Deflecting propulsion jets ROLLSROYCE (1971) Ltd 9 Jan 1973 [15 Dec 1971] 58185/71 Heading B7G In a ducted fan engine comprising a core engine 12 driving a front fan 14 enclosed within a cowl 18, the cowl is attached to the core engine by airflow straightener vanes, some of which are adjustable about axes 30 to blank off the duet. A movable portion 22 of the cowl is linked to the adjustable vanes and when displaced exposes an annular aperture 52 through which the fan air is diverted by a cascade of vanes 26. The cowl comprises front and rear fixed portions 20, 24 and the forwardly movable portion 22. Each duct-closing vane 28 is connected by a lever to a ring 32 which is rotated within the cowl by a bellcrank lever 44 actuated through rod 42 and a further bellcrank 40 which co-operates via pin 38 with a channel-section arcuate track 36 mounted on the inner surface of portion 22. Translational movement of portion 22 by a screw and nut mechanism 48, 50 exposes the annular aperture 52 containing deflector vans 26 with subsequent rotation to a duct-closing position of vanes 28. In a further embodiment (Fig. 6, not shown) the cowl is formed by a fixed aft portion and a translatable forward portion.
