    Abstract: A propulsive engine rotor (110) configured for operation within a gas turbine includes a plurality of spaced airfoil blades (120) circumferentially affixed to an outer hoop-style rim (122). At least two of the airfoil blades (120) have an integral root (140) configured to extend either through or at least radially inwardly from the rim (122). A woven fiber system provides that the blade roots (140) are interdigitally wrapped by a plurality of woven fibers (132) before impregnation and/or encapsulation of the fibers (132) and wrapped roots (140) within a ceramic or other composite matrix material to form a composite ring. The composite ring defines the interior body of the rotor (110), includes a bore (116) through which passes the rotational axis of the rotor (110), and has a lower mass than the rotor rim (122). The woven fiber interface between the roots (140) increases the tensile load capacity of the airfoil blades (120) relative to the composite ring, and increases the self-sustaining radius of the rotor (110).

    Abstract: A structurally-reinforced rotor disk (56) for a gas turbine engine (10) is disclosed. The rotor disk (56) may comprise a body (57) including a rim (58) configured to support airfoils (54) (which may be separate or integral with the airfoils), an axially-extending bore (60) disposed radially inward of the rim (58), and a radially-extending web (64) connecting the rim (58) and the bore (60). The bore (60) may include an axial outer edge (76) and at least one circumferentially-extending annular recess (70) formed axially between the outer edge (76) and the web (64). The rotor disk (56) may further comprise an annular ring (68) retained in the annular recess (70), and the annular ring (68) may be formed from a different material than the body (57) of the rotor disk (56) so as to increase a self-sustaining radius (SSR) of the rotor disk (56).
