An improved structural strut for use in the fan section of a high bypass ratio gas turbine engine is described. The strut includes two I-beam shaped structural supports which are substantially perpendicular to each other, and extend along the major and minor axes of the strut, from the strut base to the strut tip. Face sheets, preferably made of composite material, are attached to both of the I-beam supports for acoustic damping effects.
