Abstract: A rotor disk assembly (100) may include a rotor disk (110) and a retention ring (120) coupled to the rotor disk (110). Generally, the retention ring (120) is tuned to adjust a modal frequency response of the rotor disk (110)/rotor disk assembly (100). In various embodiments, dimensions of the retention ring (120) vary circumferentially. In various embodiments, the retention ring (120) includes an axially extending flange (121) and a radially extending flange (123). A radial thickness of the axially extending flange (121) may vary circumferentially and/or an axial thickness of the radially extending flange (123) may vary circumferentially.

Abstract: The present disclosure provides devices related to aircraft engine fan assemblies (300) and blade lock retainers (210). In various embodiments, a blade lock retainer (210) is formed from sheet metal and comprises an annular ring portion (211), an outer retainer tab portion (212), and an inner tab portion (213). In various embodiments, the outer retainer tab portion (212) is disposed on an outer circumference of the annular ring portion (211), oriented substantially perpendicular to the annular ring portion (211), and extends in an aft direction from the annular ring portion (211). In various embodiments, the inner retainer tab portion (213) is disposed on an inner circumference of the annular ring portion (211) and radially aligned with the outer retainer tab portion (212), oriented substantially perpendicular to the annular ring portion (211), and extends in a forward direction from the annular ring portion (211).

Abstract: A fan section for a gas turbine engine includes a fan hub having blade slots for receiving a root of a fan blade. A lock ring is configured to move rotatably from an unlocked position to a locked position for securing the blade root in the blade slot. A nose cone is secured to the lock ring, and thereby secured to the fan section.
