Abstract: A gas turbine engine fan blade lock assembly includes a fan hub that has blade slots each configured to receive a root of a fan blade. The fan hub includes circumferentially spaced first slots. A lock ring is configured to move between unlocked and locked positions. The lock ring includes circumferentially spaced second slots aligned with the first slots in the locked position, and multiple discrete pins. Each pin is configured to be slidably received in paired first and second slots in the locked position to prevent rotational movement of the lock ring relative the fan hub.
Abstract translation: 燃气涡轮发动机风扇叶片锁定组件包括风扇毂，其具有各自被配置为接收风扇叶片的根部的叶片槽。 风扇毂包括周向间隔开的第一槽。 锁定环配置为在未锁定位置和锁定位置之间移动。 锁定环包括在锁定位置与第一槽对准的周向间隔开的第二槽和多个分立的销。 每个销被构造成在锁定位置可滑动地容纳在成对的第一和第二槽中，以防止锁环相对于风扇毂的旋转运动。

Abstract: A gas turbine engine fan section includes a fan hub configured to rotate about an axis. A nose cone includes a spinner operatively mounted to the fan hub. The spinner supports a first fastening element and the nose cone includes an annular cover arranged over the fastening element. The spinner and annular cover provide an aerodynamic exterior surface of the nose cone without exposed fasteners. A second fastening element cooperates with the first fastening element to secure the spinner relative to the fan hub. The first and second fastening elements are oriented transversely to the axis.
