Abstract
Official abstract text for this publication.
A rotor disk for a gas turbine engine includes a CMC hub and a rail integrated with the CMC hub opposite the multiple of CMC airfoils, the rail defines a rail platform section that tapers to a rail inner bore.
First claim
Opening claim text (preview).
What is claimed is: 1. A disk for a gas turbine engine comprising: a CMC hub defined about an axis; a rail integrated with said CMC hub, said rail defines a rail platform section that tapers to a rail inner bore; an arm integrated with said CMC hub, said arm extending axially from said CMC hub at a radial distance from said axis that is equal to a self-sustaining radius wherein mass radially inboard of said self-sustaining radius is load carrying and mass radially outboard of…
