摘要

An inlet nose cone assembly for a gas turbine comprises an inlet nose cone 15 formed of a composite material having a flange 100 extending radially inward from a first circumferentially extending location 80 for attachment to a rotor disk; an aft fairing 105 formed of a composite material having a first stiffness to mass ratio, the aft fairing 105 being integral with the inlet nose cone 15 and extending in cantilevered fashion rearward from the first circumferentially extending location; a circumferentially continuous outer ring 90 formed of a material having a second stiffness to mass ratio that is greater than the first stiffness to mass ratio of the aft fairing 105, the outer ring 99 having an interior surface attached to the exterior surface of the aft fairing and the exterior surface of the inlet nose cone.
