Abstract

710,946. Gas turbine plant. ARMSTRONG SIDDELEY MOTORS, Ltd. May 21, 1952 [June 5, 1951], No. 13262/51. Class 110(3) [Also in Group XXXIII] A guarding portion for an intake of an aircraft engine together with lever means for actuating it is operated by a fluid-actuated mechanism having flow-control means adapted to reduce the speed of movement of the guarding portion as it approaches its extremity of travel in either direction. The intake. such as that of an axial-flow compressor, comprises an annular casing 14 and a central fairing inter-connected by radial webs 16. The annular passage upstream of the casing 14 is guarded by trapezoidal sections 18. each of which consists of a central lever 20, a frame 24 and parallel slats 21 of aerofoil section. The lever, slats and frame are interconnected by tie rods 22 which are brazed thereto and the slats are brazed to the frame 24. Each section carries two guides 25 for directing debris into an annular collecting chamber 26. Each lever is pivoted to the casing 14 at 31 and is operated by a pneumatic ram 36 through a pivoted link 38. Each lever is also connected to the ram casing by a pivoted spring link 32. The rams are fed in parallel by air from the compressor and each ram has by-pass means whereby in the event of failure of any of the rams the remaining rams will not be affected. The collecting chamber is defined at the front by a circumferential flange on a casing portion 33 which is supported from the casing 14 by brackets 74, 75. The brackets 74, 75 are welded to members 76 and the brackets 75 are bolted to the casing 14. The outer wall of the collecting chamber is formed by a detachable. flexible band 86 which is mounted on a ring 33a and a flange 98, with the interposition of rubber seals 88, as shown. Reference has been directed by the Comptroller to Specification 668,638.
