Abstract
A fan exit guide vane with a load member and cooling cavity including an inner attachment region opposite an outer attachment region; a load member cavity formed within the fan exit guide vane extending spanwise through the fan exit guide vane from the inner attachment region to the outer attachment region; the load member extending through the load member cavity beyond each of the inner attachment region and the outer attachment region of the fan exit guide vane; and a cooling cavity formed within the fan exit guide vane extending spanwise through the fan exit guide vane between the inner attachment region and the outer attachment region.
