Abstract: A rotor body rotates about an axis of rotation. A ledge provides a holding structure for holding blades. A plurality of blades are positioned beneath the ledge, load slot is sized to allow a mount portion of the blades to be moved radially inwardly of the ledge. The blades are moved circumferentially to have the mounted structure radially inwardly of the ledge. A lock slot is positioned on one circumferential side of the load slot. The lock slot is formed to receive a lock, and the lock is partially received within a portion of at least one of the blades, to lock the blades within the rotor, and a shield slot on a second circumferential side of the load slot. The shield slot is sized to be different from the lock slot such that a lock cannot be inadvertently positioned within the shield slot.

Abstract translation: 转子体围绕旋转轴线旋转。 壁架提供了用于保持叶片的保持结构。 多个叶片定位在壁架下方，负载槽的尺寸被设计成允许叶片的安装部分在壁架的径向内部移动。 叶片沿周向移动以使凸缘的径向向内具有安装结构。 锁槽位于装载槽的一个圆周侧。 锁槽形成为接收锁，并且锁部分地容纳在至少一个叶片的一部分内，以将叶片锁定在转子内，以​​及在装载槽的第二周向侧上的屏蔽槽。 屏蔽槽的尺寸与锁定槽的尺寸不同，使得锁不能无意中定位在屏蔽槽内。

Abstract: Hollow fan blades for gas turbine engines are disclosed. The hollow fan blades include a body having a convex side and a concave side wherein the convex side has a cavity formed therein. The cavity is covered by two covers including an inner cover that may be adhered to the body of the fan blade assembly and an outer cover that may be adhered to the inner cover and/or the body of the fan blade assembly. The covers may be made of titanium, more than two covers may be employed and more than one cavity may be employed.
