A flow control arrangement ( 30; 50; 70 ) is described in which an inlet slot 35, 55, 85 is positioned prior to a stationary structure ( 33; 43; 53; 73; 83 ) such as a stator or pylon in order that air flow is bled or removed from a main flow 31, 51, 81 . The removed air passes through a passage duct 36, 56 and is re-injected through an outlet nozzle 37, 57, 87 with an askew angle consistent with rotor blades 32, 52, 72, 82 of a turbine. In such circumstances, distortion in the flow due to the stationary structure 33, 43, 53, 83 is relieved such that there is less instability downstream from that structure 33, 43, 53, 83. |
