1. An outlet guide vane (OGV) structure for a gas turbine engine, the OGV structure comprising:
a plurality of radially extending guide vanes;
wherein at least one guide vane in the plurality of radially extending guide vanes comprises:
a pressure surface defining a first side of the at least one guide vane and an opposing suction surface defining a second side of the at least one guide vane; and
at least one air inlet allowing air to pass into at least one internal cavity within the at least one guide vane and at least one air outlet arranged on a trailing edge allowing the air to exit the at least one internal cavity, the at least one internal cavity being defined between the first side and the second side of the at least one guide vane;
wherein at least one conduit is within the at least one internal cavity and configured to communicate a fluid therethrough;
wherein the at least one air inlet is arranged upstream of the at least one air outlet in a direction of airflow over the at least one guide vane, and the at least one air inlet is arranged only through the pressure surface of the at least one guide vane and spaced from a leading edge of the opposing suction surface.
