Abstract
1522975 Gas turbine engines; compressor bleed GENERAL ELECTRIC CO 17 Oct 1975 [29 Oct 1974] 42705/75 Headings F1C and F1G The invention relates to a gas turbine engine in which means are provided for bleeding air from the compressor, the air bleeding means comprising a manifold having a plurality of outlets, a checkvalve being disposed in each passage. The object of the invention is to ensure that in the event of circumferential inequalities of pressure, air will be bled from higher pressure regions and not from lower pressure regions. The compressor shown comprises an inner stator casing 14 which supports stator blades 18, and an outer casing 13 which define therebetween a plenum space 32 to which bleed air flows. Air is bled from the compressor flow-path through a series of passages 38 formed in a ring member 34, the air then passing to a series of chambers 42 formed in a manifold 36. A check-valve 37 is associated with each chamber 42 and comprises a cylindrical housing 46 having a series of slots 50 in the wall thereof and a flat disc valve 47 movable between the two end positions shown. The disc valve when in the full line position effectively prevents flow through the valve and when in the broken line position allows bleed air to flow from the passage 38 to the plenum space 32. Further air is bled from the compressor discharge through passage 28A to chamber 27 thence through duct 31 to the point of use.
