Abstract
A hollow prop-fan aerofoil blade is covered by a woven containment sheath which is bonded to the aerofoil surface of the blade and operationally anchored to the blade root. The sheath is arranged to be of sufficient strength to contain any of the aerofoil cross-section portion of the blade in the event of any structural failure thereof.
