A design and structural analysis of a CH-54B MAIN ROTOR HUB FABRICATED FROM COMPOSITE MATERIALS IS MADE TO ASSESS THE FLIGHTWORTHINESS OF A HUB CONSISTING BASICALLY OF TENSION STRAPS FABRICATED FROM GRAPHITE EPOXY AND FIBERGLASS. The concept is feasible but not competitive with the production titanium hub from a weight standpoint.
