  "textContent": "A gas turbine engine (100) includes a core engine casing (114), a bypass duct (122) and a core engine duct (111). The gas turbine engine (100) further includes a plurality of flaps (130) pivotally coupled to the core engine casing (114) and arranged circumferentially around a principal rotational axis (102). Each flap (130) extends from a first casing end (116) and is configured to pivotally rotate relative to core engine casing (114) about a pivot axis (P) between a first position (X1) and a second position (X2). In the first position (X1), each flap (130) is disposed in a circumferential direction (C) and is radially disposed between a plurality of OGVs (140) and a plurality of stator vanes (142). In the second position (X2), each flap (130) is inclined to the first position (X1) and extends at least partially into the bypass duct (122) and the core engine duct (111).",
