ABSTRACT:
A root attachment for a turbine blade is integrally molded with a composite turbine blade for a ram air turbine. The root attachment includes an insert at the one end of the root attachment for integrally molding within the blade and a hub connector at an opposite end for connecting the blade to a rotor hub. The insert has a geometry and surface area such that a dual load carrying capability is achieved during molding by the formation of an adhesive bond between the material of the blade and the insert and also a mechanical locking which resists failure in bearing. Each of the adhesive bond and the mechanical locking is designed to fail above an ultimate design load.
