GAS TURBINE ENGINE WITH IMPROVED VARIABLE INLET GUIDE VANE SHIELDING

A gas turbine engine comprises: a fan rotating about an engine main axis; a core duct; an engine core; an Engine Section Stator (ESS) comprising a plurality of ESS vanes and arranged in the core duct downstream of the fan; and a plurality of variable inlet guide vanes (VIGV) adapted to rotate about a pivot axis and arranged in the core duct downstream of the ESS. The VIGV vanes are arranged angularly rotated with respect to the ESS vanes such that the VIGVs are shielded by the ESS, thereby protecting the VIGVs from icing and from ice shedding from the ESS vanes.
