A system for extracting foreign matter in a gas turbine includes multiple variable bleed valve (VBV) doors disposed on the outer engine casing between a low pressure compressor and a high pressure compressor for bleeding a portion of flow from a core engine flow path into a bypass flow path. The system includes an outlet guide vane (OGV) assembly having multiple guide vanes disposed within the core flow path and multiple support struts positioned downstream from the multiple guide vanes. Each pairs of adjacent support struts comprises at least one VBV door therebetween and a section of the OGV assembly located at an upstream side of the fan hub frame before the each pairs of adjacent support struts. Each section of the OGV assembly includes a first side with one or more guide vanes with trimmed trailing edges configured for directing flow into the at least one VBV door.
