Composite reinforced rotor

A component of a rotor system, comprising:

• a disk comprising:
• an airfoil element;
• a web extending radially inwardly from the airfoil element;
• a first arm element extending axially forwardly from the web and comprising a first ring retaining feature;
• a second arm element extending axially aft from the web and comprising a second ring retaining feature;
• and
• a bore, which has a maximum width that is narrower than a minimum width of the airfoil element;
• and
• first and second reinforcing rings formed of fiber reinforced materials, the first and second reinforcing rings being disposed to fit about the first and second arm elements, respectively, and to be axially retained by the first and second ring retaining features, respectively,
• wherein the first and second reinforcing rings have conical shapes characterized with uppermost surfaces which are level with the upper edges of the first and second ring retaining features, respectively, and decreasing radial thickness with respectively increasing forward and aft axial distances from the web and the first and second arm elements have conical shapes complementing the conical shapes of the first and second reinforcing rings, respectively.

A component of a rotor system having a rotor or hub element, the component of the rotor system comprising:

• a disk comprising an airfoil element, a web extending radially inwardly from the airfoil element and first and second arm elements extending axially forwardly and aft from the web, respectively, with first and second ring retaining features;
• a bore disposed at an end of the web;
• and
• first and second reinforcing rings formed of fiber reinforced materials and disposed to fit about the first and second arm elements, respectively,
• wherein the web has a length that positions the bore to radially accommodate the rotor or hub element with radial space between the bore and the rotor or hub element,
• wherein the first and second reinforcing rings have conical shapes characterized with uppermost surfaces which are level with the upper edges of the first and second ring retaining features, respectively, and decreasing radial thickness with respectively increasing forward and aft axial distances from the web and the first and second arm elements have conical shapes complementing the conical shapes of the first and second reinforcing rings, respectively.
