Abstract
A gas bleed arrangement for a gas turbine engine. The gas bleed arrangement includes an annular casing defining a main gas flow path. The annular casing has a plurality of bleed ducts each defining a respective bleed flow path. The arrangement further includes a blocking element having at least one aperture. The blocking element is moveable to align the at least one aperture at least partly between the main gas flow path and at least one of the bleed flow paths to control fluid communication between the main gas flow path and the at least one of the bleed flow paths through the aperture.
